A new galloylglucoside from Cleyera ochnacea DC. (1/10)
A new galloylglucoside, 3-hydroxy-5-methylphenol 1-O-beta-D-(6'-galloyl)glucopyranoside (1) was isolated from Cleyera ochnacea DC. (Theaceae). Its structure was elucidated on the basis of chemical and spectral analysis. Compound 1 showed inhibitory activity against rat cerebellar nitric oxide synthase (NOS).

(2/10)
Cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) are involved in various pathophysiological processes such as inflammation and carcinogenesis. In a search for inhibitors of COX-2 and iNOS production we found that extracts of Stewartia koreana strongly inhibited NO and PGE2 production in LPS-treated macrophage RAW 264.7 cells. We have now shown that the mRNA and protein levels of iNOS and COX-2 are reduced by the Stewartia koreana extract (SKE). SKE inhibited expression of an NF-kappaB reporter gene in response to LPS, and gel mobility shift assays revealed that SKE reduced NF-kappaB DNA-binding activity. The extract also inhibited LPS-induced phosphorylation of IkappaB-alpha and nuclear translocation of p65. Administration of the extract reduced the symptoms of arthritis in a collagen-induced arthritic mouse model. These results indicate that Stewartia extracts contain potentially useful agents for preventing and treating inflammatory diseases.

(+info)A glycosidic spinasterol from Koreana stewartia promotes procollagen production and inhibits matrix metalloproteinase-1 expression in UVB-irradiated human dermal fibroblasts. (5/10)
Methanol extract of Koreana stewartia leaves (SKE) stimulated collagen production in ultraviolet-B (UVB)-irradiated human fibroblast cells. An active compound was isolated from SKE by successive partitioning and chromatography, and the chemical structure was determined to be 3-O-beta-D-glucopyranosylspinasterol (spinasterol-Glc) by spectroscopic characterization. Spinasterol-Glc increased collagen production in the supernatant of UVB-irradiated dermal fibroblast cell cultures in a dose-dependent manner. The effects of spinasteol-Glc on expression of procollagen and matrix metalloproteinase-1 (MMP-1) were further evaluated. We found that the compound stimulated collagen production in UVB-treated fibroblasts than in vehicle-treated control cells by about 3-fold. In addition, we also demonstrate that the compound increased the mRNA and protein levels of procollagen in UVB-treated fibroblast cells, while it inhibited expression of MMP-1. These results indicate that spinasterol-Glc protects fibroblast cells from the adverse effects of UV radiation via stimulation of procollagen synthesis as well as inhibition of MMP-1 expression. Spinasterol-Glc may be useful in the future development of therapeutic and cosmetic applications.

(+info)Three new orcinol-conjugated hydrolysable tannins from the leaves of Cleyera japonica. (8/10)
Three new orcinol (3-hydroxy-5-methylphenol)-conjugated hydrolysable tannins, together with two known compounds were isolated from the leaves of Cleyera japonica (CJ), and have been tentatively named cleyeratannin A (1), cleyeratannin B (2) and cleyeratannin C (3). The chemical structures of these compounds were elucidated using 1 dimensional (1D)/2D NMR and high resolution FAB-MS, and the absolute configuration was confirmed by circular dichroism (CD). To evaluate their anti-oxidative activities, 1,1-diphenyl-2-picrylhydrazyl (DPPH)/free radical scavenging activity and nitroblue tetrazolium (NBT)/superoxide anion scavenging activity were determined. (+info)"Camellia" is a botanical term that refers to a genus of evergreen shrubs and trees in the family Theaceae. There are over 250 species of Camellias, which are native to Asia, primarily China and Japan. Many Camellia species are cultivated for their attractive flowers, and some are used for their oil-rich seeds.
The most well-known species is Camellia sinensis, which is the source of tea leaves used to make black, green, and oolong teas. The caffeine content in these teas comes from xanthines found in the leaves of this plant.
Camellias are not typically associated with medical definitions or uses, but some research suggests that compounds found in Camellia sinensis may have potential health benefits, such as reducing the risk of cardiovascular disease and cancer. However, more research is needed to confirm these findings and establish safe and effective dosages.
"Theaceae" is not a medical term, but a taxonomic category in botany. It refers to a family of flowering plants that includes the tea plant (Camellia sinensis), as well as other related genera. Theaceae is part of the order Ericales and contains around 20 genera and about 600 species.
The medicinal relevance of Theaceae comes primarily from the tea plant, which has been used for centuries in traditional medicine to treat a variety of ailments, including digestive disorders, headaches, and fatigue. Green and black teas made from the leaves of Camellia sinensis contain bioactive compounds such as catechins, theaflavins, and thearubigins, which have been shown to have antioxidant, anti-inflammatory, and potential health benefits. However, it's important to note that while some studies suggest possible health advantages of tea consumption, more research is needed to fully understand its effects and potential therapeutic applications.
'Camellia sinensis' is the scientific name for the plant that is used to produce tea. It is an evergreen shrub native to East Asia, particularly China and India, and has been cultivated for thousands of years for its leaves, which are used to make various types of tea, including black, green, oolong, and white teas.
The leaves of 'Camellia sinensis' contain a number of bioactive compounds, including caffeine, theophylline, and theobromine, as well as polyphenols such as flavonoids and catechins, which are believed to have various health benefits. The processing method used on the leaves determines the type of tea produced and its color, flavor, and chemical composition.
