Seed germination, phenology, and antiedematogenic activity of Peperomia pellucida (L.) H. B. K. (1/10)
BACKGROUND: Peperomia pellucida is popularly known as coracaozinho in the Brazilian northeast and is used in the treatment of abscesses, furuncles, and conjunctivitis. Our work aimed to determine the term of the development stages and the species cycle in the four seasons of the year (complete development, beginning of bloom, complete bloom, and seed set), verifying the plant's therapeutic profile during the four distinct development phases in order to detect differences in its potency. Pharmacological tests were performed to observe the anti-inflammatory activity. RESULTS: Phenological observations were accessed for a 12 month-period, from the Brazilian summer of 1999/2000 to fall 2000. On average the plantules' emergence occurred 15 days after seeding. All plantules grew in a similar manner up to 25 days after transplantation in all seasons. Starting on the 25th day, we observed faster growth during spring, with plants reaching a height of about 60 cm after 100 days of transplantation, unlike other seasons, in which plants reached heights of 40, 40, and 35 cm during winter, summer, and fall, respectively. The P. pellucida aqueous extract showed significant anti-inflammatory activity during phenophases 1 and 2 of winter and spring. Depending on the plant's phenophase there was variation in the potency of edema inhibition. CONCLUSION: P. pellucida has a phenological cycle of approximately 100 days. It is recommended that the P. pellucida aqueous extract is used as an antiedematogenic only during phenophases 1 and 2 of winter and spring.

Peperomia pellucida leaf extract was characterized for its anticancer, antimicrobial, antioxidant activities, and chemical compositions. Anticancer activity of P. pellucida leaf extract was determined through Colorimetric MTT (tetrazolium) assay against human breast adenocarcinoma (MCF-7) cell line and the antimicrobial property of the plant extract was revealed by using two-fold broth micro-dilution method against 10 bacterial isolates. Antioxidant activity of the plant extract was then characterized using alpha, alpha-diphenyl-beta-picrylhydrazyl (DPPH) radical scavenging method and the chemical compositions were screened and identified using gas chromatography-mass spectrometry (GC-MS). The results of present study indicated that P. pellucida leaf extract possessed anticancer activities with half maximal inhibitory concentration (IC(50)) of 10.4 +/- 0.06 microg/ml. The minimum inhibitory concentration (MIC) values were ranged from 31.25 to 125 mg/l in which the plant extract was found to inhibit the growth of Edwardsiella tarda, Escherichia coli, Flavobacterium sp., Pseudomonas aeruginosa and Vibrio cholerae at 31.25 mg/l; Klebsiella sp., Aeromonas hydrophila and Vibrio alginolyticus at 62.5 mg/l; and it was able to control the growth of Salmonella sp. and Vibrio parahaemolyticus at 125 mg/l. At the concentration of 0.625 ppt, the plant extract was found to inhibit 30% of DPPH, free radical. Phytol (37.88%) was the major compound in the plant extract followed by 2-Naphthalenol, decahydro- (26.20%), Hexadecanoic acid, methyl ester (18.31%) and 9,12-Octadecadienoic acid (Z,Z)-, methyl ester (17.61%). Findings from this study indicated that methanol extract of P. pellucida leaf possessed vast potential as medicinal drug especially in breast cancer treatment.

(+info)I'm sorry for any confusion, but "Peperomia" is not a medical term. It is a genus of plants in the family Piperaceae, commonly known as radiator plants or baby rubber plants. These plants are popular as houseplants due to their attractive foliage and ease of care. If you have any questions about a specific medical concern or condition, I would be happy to try to help with that instead.
Cyperaceae is a family of monocotyledonous plants that are commonly known as sedges. This family includes around 5,500 species that are distributed worldwide, with the greatest diversity found in tropical and subtropical regions. The plants in this family are typically characterized by their triangular stems and narrow, grass-like leaves.
The inflorescences of Cyperaceae species are often composed of tightly packed spikelets, which contain tiny flowers that are usually reduced to only the essential reproductive parts. Many sedges also have distinctive, hardened bracts that surround the base of the inflorescence and can be used to help identify the plant to species level.
Cyperaceae species are important components of many ecosystems, including wetlands, grasslands, and forests. Some species are grown as ornamental plants, while others have economic importance as sources of food, fiber, and medicine. For example, papyrus sedge (Cyperus papyrus) was used in ancient Egypt to make paper, and yellow nutsedge (Cyperus esculentus) produces edible tubers that are consumed in some parts of the world.
It's worth noting that Cyperaceae species can be difficult to identify due to their small flowers and similar morphology, so a proper identification often requires careful examination of multiple plant features.
Piperaceae is not a medical term but a taxonomic category in botany, referring to the Pepper family of flowering plants. However, I can provide some general information about it.
Piperaceae is a family of flowering plants that includes around 3,600 species distributed across 55 genera. The family is particularly diverse in tropical regions, and many of its members are economically important as spices, ornamentals, and medicinal plants.
One of the most well-known members of Piperaceae is Piper nigrum, which produces black pepper, one of the most commonly used spices worldwide. Another member of the family is Piper methysticum, also known as kava, a plant native to the Pacific Islands that has been traditionally used for medicinal and ceremonial purposes.
While Piperaceae is not a medical term itself, some of its members have medicinal properties and are used in various traditional medicine systems. For example, black pepper has been used in Ayurvedic medicine for its anti-inflammatory and digestive properties, while kava has been used to treat anxiety and insomnia. However, it's important to note that the scientific evidence supporting these uses is limited, and more research is needed to confirm their safety and efficacy.
