油桐叶和根化学成分的研究

Chemical Constituents of leaves and roots of Vernicia Fordii

为了研究油桐(Vernicia FOrdii)的叶、根的化学成分,运用柱层析及高效液相色谱法的分离方法,并利用物理、化学及波谱方法,首次从油桐的叶、根中分离鉴定了6个化合物,它们是β-谷甾醇(Ⅰ)、槲皮素-3-O-α-L-吡喃鼠李糖苷(Ⅱ)、杨梅素-3-O-α-L-吡喃鼠李糖苷(Ⅲ)、羽扇豆醇(Ⅳ)、白桦酸(Ⅴ)和齐墩果酸(Ⅵ).

To study the chemical constituents of the leaves and roots of Vernicia Fordii, six compounds were isolated from the 95% ethanol extract of the leaves and roots of Ⅴ. Fordii for the first time. On the basis of spectral data or by comparison with authentic samples, they were identified as flsitosterol（Ⅰ）, quercetin - 3 - O-β-D- rhamaopyranoside （Ⅱ） , myricetin-3-O-α-L-rhamaopyranoside （ Ⅲ）, lupeol （Ⅳ）, betulic acid（Ⅴ ） and oleanolic acid（Ⅵ）.
