海南山苦茶叶的化学成分研究Ⅰ

Studies on chemical constituents in leaves of Mallotus furetianus Ⅰ

目的:研究海南山苦茶叶的化学成分。方法:运用溶剂法和色谱法进行成分的分离和纯化,通过理化性质和光谱数据的解析,鉴定化合物的结构。结果:首次从海南山苦茶叶中分离出8个化合物,分别鉴定为3-羟基-4,5(R)-二甲基-2(5H)-呋喃酮(Ⅰ),没食子酸(Ⅱ),(6S,9R)-6-羟基-3-酮-α-紫罗兰醇-9-O-β-D-葡萄糖苷(Ⅲ),(Z)-3-己烯醇-β-D-葡萄糖苷(Ⅳ),3,4,8,9,10-五羟基-二苯并[b,d]吡喃-6-酮(Ⅴ),木栓醇(Ⅵ),β-谷甾醇(Ⅶ),木栓酮(Ⅷ)。结论:以上化合物均为首次从该植物中获得。

Objective： To investigate the chemical compounds in leaves of Mallotus furetianus. Method：The chemical components were isolated by solvent extraction and chromatography. The structures were identified on the basis of physico-chemical constant and spectral data. Result： Eight compounds were isolated and identified as 3-Hydroxy-4, 5 （ R）-dimethyl-2（SH）-furanone （ Ⅰ ）, gallic acid （ Ⅱ）, （6S, 9 R ）-roseoside （ Ⅲ ）, （ Z ）-3-Hexenyl-β- D-glucopyranoside （ Ⅳ ）, 3, 4, 8, 9, 10-Pentahydroxy-dibenzo [ b, d ] pyran-6-one （ Ⅴ ）, friedelinol （Ⅵ）, β-sitosterol （Ⅶ）, friedelin （Ⅷ）. Conclusion： Compounds Ⅰ-Ⅶ were obtained for the first time from this plant.
