霉茶化学成分研究(Ⅱ)

Studies on the Chemical Constituents of MEICHA(Ⅱ)

目的:研究霉茶的化学成分。方法:用色谱法和光谱分析法分离和鉴定其化学成分。结果:分离得到了7个化合物,分别为β-谷甾醇(Ⅰ)、齐墩果酸(Ⅱ)、槲皮素(Ⅲ)、花旗松素(Ⅳ)、儿茶素(Ⅴ)、槲皮素-3-O-α-L-鼠李糖苷(Ⅵ)、没食子酸(Ⅶ)。结论:7个化合物均为首次从该植物中得到。

Objective ： To study the chemical constituents of MEICHA. Methods ： Chromatography and spectroscopic analysis were employed to isolate and elucidate the chemical constituents in the plant. Results： Seven compounds were obtained and identified as/3- sitosterol（ Ⅰ ）, oleanolie acid（ Ⅱ ）, quercetin（ Ⅲ ）, Taxifolin（ Ⅳ ）, Cateehin（ Ⅴ ）, Quereeetin-3-O-α-L-rhamnoside（ Ⅵ ） and Gallic acid（ Ⅶ ）. Conclusion： Seven compounds are isolated from this plant for the first time.
