Effect of dried fruits of Solanum nigrum LINN against CCl4-induced hepatic damage in rats. (1/19)
Ethanol extract of Solanum nigrum LINN was investigated for its hepatoprotective activity against CCl4-induced hepatic damage in rats. The ethanol extract showed remarkable hepatoprotective activity. The activity was evaluated using biochemical parameters such as serum aspartate amino transferase (AST), alanine amino transferase (ALT), alkaline phosphatase (ALP) and total bilirubin. The histopathological changes of liver sample in treated animals were compared with respect to control. (+info)Begomovirus genetic diversity in the native plant reservoir Solanum nigrum: Evidence for the presence of a new virus species of recombinant nature. (2/19)
We examined the native plant host Solanum nigrum as reservoir of genetic diversity of begomoviruses that cause the tomato yellow leaf curl disease (TYLCD) emerging in southern Spain. Presence of isolates of all the species and strains found associated with TYLCD in this area was demonstrated. Mixed infections were common, which is a prerequisite for recombination to occur. In fact, presence of a novel recombinant begomovirus was demonstrated. Analysis of an infectious clone showed that it resulted from a genetic exchange between isolates of the ES strain of Tomato yellow leaf curl Sardinia virus and of the type strain of Tomato yellow leaf curl virus. The novel biological properties suggested that it is a step forward in the ecological adaptation to the invaded area. This recombinant represents an isolate of a new begomovirus species for which the name Tomato yellow leaf curl Axarquia virus is proposed. Spread into commercial tomatoes is shown. (+info)Systemin in Solanum nigrum. The tomato-homologous polypeptide does not mediate direct defense responses. (3/19)
We extend Ryan's seminal work on the 18-amino acid polypeptide systemin in tomato's (Solanum lycopersicum) systemic wound response to the closely related solanaceous species Solanum nigrum. We compared wild-type plants to plants transformed with an inverted repeat prosystemin construct (IRSys) to silence the expression of the endogenous S. nigrum prosystemin gene. In wild-type plants elicited with wounding + oral secretions from Manduca sexta larvae, trypsin-proteinase inhibitors (TPIs) accumulated even though prosystemin transcripts were down-regulated. Neither reducing the endogenous systemin levels by RNAi nor complementing the plants with systemin by exogenously supplying the polypeptide through excised stems significantly increased TPI activity, indicating that systemin and TPIs are not correlated in S. nigrum. The performance of two herbivore species from two feeding guilds, M. sexta larvae and Myzus persicae nicotianae, did not differ between wild-type and IRSys plants, demonstrating that varying endogenous systemin levels do not alter the direct defenses of S. nigrum. Field experiments with wild-type and IRSys plants and the flea beetle Epitrix pubescens supported these glasshouse data. That levels of oral secretion-elicited jasmonic acid did not differ between wild-type and IRSys plants suggests that systemin is unlikely to mediate jasmonate signaling in S. nigrum as it does in tomato. We conclude that the tomato-homologous polypeptide does not mediate direct defense responses in S. nigrum. (+info)Antinociceptive, anti-inflammatory and antipyretic effects of Solanum nigrum chloroform extract in animal models. (4/19)
AIM: The present study was carried out to evaluate the antinociceptive, anti-inflammatory and antipyretic effects of chloroform extract of Solanum nigrum leaves using various animal models. METHODS: The extract was prepared by soaking (1:20; w/v) the air-dried powdered leaves (20 g) in chloroform for 72 hrs followed by evaporation (40 degrees C) under reduced pressure to dryness (1.26 g) and then dissolved (1:50; w/v) in dimethylsulfoxide (DMSO). The supernatant, considered as the stock solution with dose of 200 mg/kg, was diluted using DMSO to 20 and 100 mg/kg, and all doses were administered (s.c.; 10 ml/kg) in mice/rats 30 min prior to tests. RESULTS: The extract exhibited significant (p<0.05) antinociceptive activity when assessed using the abdominal constriction, hot plate and formalin tests. The extract also produced significant (p<0.05) anti-inflammatory and antipyretic activities when assessed using the carrageenan-induced paw edema and brewer's yeast-induced pyrexia tests. Overall, the activities occurred in a dose-independent manner. CONCLUSION: The present study demonstrated that the lipid-soluble extract of S. nigrum leaves possessed antinociceptive, anti-inflammatory and anti-pyretic properties and confirmed the traditional claims. (+info)Salinity stress enhances production of solasodine in Solanum nigrum L. (5/19)
Various in vitro grown tissues (non-regenerative callus, regenerative callus and microshoot derived leaves) of Solanum nigrum L. were cultured under salinity stress (0-150 mM NaCl) for enhanced production of solasodine, a steroidal alkaloid and an alternative to diosgenin, which is used as a precursor for the commercial production of steroidal drugs. The role of plant growth regulators and various concentrations of NaCl during in vitro production of solasodine was studied. The in vitro yield was compared with the yield from leaves of field grown plant. Solasodine content was maximum (2.39 mg/g dry wt.) in regenerative callus when grown on medium added with 150 mM NaCl; followed by in vitro raised leaf of microshoot. Quantitative estimation of solasodine was carried out using a new HPTLC method, which is validated for its recovery and precession. The proposed HPTLC method showed a good linear relationship (r(2)=0.994) in 50-2000 ng/spot concentration ranges. The data demonstrate that the solasodine production in cultures was growth dependent.

(+info)Anti-seizure activity of the aqueous leaf extract of Solanum nigrum linn (solanaceae) in experimental animals. (7/19)
BACKGROUND: Solanum nigrum is claimed in traditional medical practice, to be useful in the treatment of epilepsy in some parts of Nigeria. OBJECTIVES: To study the anti-convulsant property of the aqueous extract of the leaves of S. nigrum in chicks, mice and rats. METHOD: Aqueous extracts were administered intraperitoneally, at a pre-treatment time of 30 minutes, at graded doses and animals were challenged with different types of proconvulsants. RESULTS: The aqueous leaf extract produced a significantly (P<0.05) dose dependent protection against electrically-induced seizure in chicks and rats, pentylenetetrazole-induced seizure in mice and rats and picrotoxin-induced seizure in mice and rats. The anti-seizure property of the extract was potentiated by amphetamine. CONCLUSION: The result obtained in this study suggests that the leaves of this plant may possess anti-convulsant property in chicks, mice and rats.

(+info)"Solanum nigrum" is the scientific name for a plant species that is commonly known as black nightshade. It belongs to the family Solanaceae, which also includes other well-known plants such as tomatoes, potatoes, and eggplants.
Black nightshade is an annual or short-lived perennial herb that can grow up to 1 meter tall. The plant has simple, alternate leaves that are usually dark green in color and have a slightly hairy texture. The flowers of the black nightshade are small and white with yellow centers, and they produce round, shiny black berries that contain numerous seeds.
While some parts of the black nightshade plant, including the berries, are edible and can be used in cooking, it is important to note that all parts of the plant contain solanine, a toxic alkaloid that can cause symptoms such as nausea, vomiting, diarrhea, and dizziness if ingested in large quantities. Therefore, it is generally recommended to avoid consuming any part of the black nightshade plant unless it has been properly prepared by a knowledgeable source.
In medical contexts, "Solanum nigrum" may be mentioned in relation to its potential medicinal properties or as a cause of toxicity if ingested in large quantities. However, it is not typically used as a medical treatment or therapy.
'Piper nigrum' is not a medical term, but it is a botanical name. It refers to the black pepper plant, which is native to South India and Southeast Asia. The fruit of the plant, known as peppercorns, is used as a spice and has various medicinal properties.
Black pepper contains piperine, an alkaloid that gives it its pungent flavor and may have several health benefits, such as improving digestion, reducing inflammation, and enhancing bioavailability of nutrients in other foods when consumed together. However, more research is needed to confirm these potential benefits and establish appropriate dosages for medical use.
"Solanum" is a genus of flowering plants that includes many species, some of which are economically important as food crops and others which are toxic. The term "Solanum" itself does not have a specific medical definition, but several species within this genus are relevant to medicine and human health. Here are some examples:
1. Solanum lycopersicum (tomato): While tomatoes are primarily known as a food crop, they also contain various compounds with potential medicinal properties. For instance, they are rich in antioxidants like lycopene, which has been studied for its potential benefits in preventing cancer and cardiovascular diseases.
2. Solanum tuberosum (potato): Potatoes are a staple food crop, but their leaves and green parts contain solanine, a toxic alkaloid that can cause gastrointestinal disturbances, neurological symptoms, and even death in severe cases.
3. Solanum melongena (eggplant): Eggplants have been studied for their potential health benefits due to their high antioxidant content, including nasunin, which has been shown to protect against lipid peroxidation and DNA damage.
4. Solanum nigrum (black nightshade): This species contains solanine and other toxic alkaloids, but some parts of the plant have been used in traditional medicine for their anti-inflammatory, analgesic, and antipyretic properties. However, its use as a medicinal herb is not well-established, and it can be toxic if improperly prepared or consumed in large quantities.
5. Solanum dulcamara (bittersweet nightshade): This species has been used in traditional medicine for various purposes, including treating skin conditions, respiratory ailments, and gastrointestinal complaints. However, its use as a medicinal herb is not well-supported by scientific evidence, and it can be toxic if ingested in large quantities.
In summary, "Solanum" refers to a genus of flowering plants that includes several species with relevance to medicine and human health. While some species are important food crops, others contain toxic compounds that can cause harm if improperly consumed or prepared. Additionally, the medicinal use of some Solanum species is not well-established and may carry risks.
Solanaceous alkaloids are a type of natural toxin found in plants belonging to the Solanaceae family, also known as the nightshade family. These alkaloids contain nitrogen and are produced by the plant as a defense mechanism against herbivores and other threats. Some common solanaceous alkaloids include nicotine, atropine, scopolamine, and solanine.
Nicotine is found in tobacco plants (Nicotiana tabacum) and is highly addictive. Atropine and scopolamine are found in belladonna (Atropa belladonna), also known as deadly nightshade, and are used in medical settings for their anticholinergic effects, but can be toxic or even fatal if ingested in large quantities. Solanine is found in potatoes, tomatoes, and eggplants, and can cause gastrointestinal symptoms such as nausea, vomiting, and diarrhea if consumed in large amounts.
It's worth noting that the levels of solanaceous alkaloids in commonly consumed plants like potatoes and tomatoes are generally low and not considered harmful to most people. However, some individuals may be more sensitive to these compounds and may experience adverse effects even at low levels.
"Ribes" is a botanical term that refers to a genus of shrubs in the family Grossulariaceae, which includes plants commonly known as gooseberries and currants. These plants are native to the temperate regions of the Northern Hemisphere and are widely cultivated for their edible fruits.
However, I believe you may be looking for a medical term related to "ribes." There is no specific medical term or condition directly related to "ribes" in the context of human health or disease. If you have any further questions or need clarification on a different medical term, please let me know!
A plant extract is a preparation containing chemical constituents that have been extracted from a plant using a solvent. The resulting extract may contain a single compound or a mixture of several compounds, depending on the extraction process and the specific plant material used. These extracts are often used in various industries including pharmaceuticals, nutraceuticals, cosmetics, and food and beverage, due to their potential therapeutic or beneficial properties. The composition of plant extracts can vary widely, and it is important to ensure their quality, safety, and efficacy before use in any application.
Phytotherapy is the use of extracts of natural origin, especially plants or plant parts, for therapeutic purposes. It is also known as herbal medicine and is a traditional practice in many cultures. The active compounds in these plant extracts are believed to have various medicinal properties, such as anti-inflammatory, analgesic, or sedative effects. Practitioners of phytotherapy may use the whole plant, dried parts, or concentrated extracts to prepare teas, capsules, tinctures, or ointments for therapeutic use. It is important to note that the effectiveness and safety of phytotherapy are not always supported by scientific evidence, and it should be used with caution and preferably under the guidance of a healthcare professional.
