    摘要: 94 年度執行國科會計畫印度紫檀之抗癌活性成分之研究乙題,本實驗室已分離出近
    二十五個化合物, 其中包括六個三萜類化合物- lupeol 、betulinic acid 、betulin 、
    betulin-3-caffeate、friedelin 及3β-friedelinol;一個醣類化合物-sucrose;6 個固醇類化合物-
    β-sitosterol、stigmasterol、β-sitosteryl-3-O-β-D-glucoside、β-sigmasteryl-3-O-β-D- glucoside、
    β-sitosterone 及stigmasterone;1 個沒食子酸類衍生物- 3,4,5-trihydroxy-benzaldhyde;以及
    十一個異黃酮類化合物- maackiain 、pterocarpine 、homopterocarpin 、angolensin 、
    3-hydroxy-1-(2-hydroxy-4-methoxyphenyl)-2-(4-methoxyphenyl)propan-1-one 、medicarpin 、
    secundiflorol I、liquiritigenin、4’-methoxyl-7-hydroxyl-2,3-dihydroisoflavone、PI-S24-4 以及
    PI-S33-2。其中pterocarpine 異黃酮類化合物為文獻所記載之紫檀主要活性成分,而
    3-hydroxy-1-(2-hydroxy-4-methoxyphenyl)-2-(4-methoxy-phenyl)propan-1-one、Afromosin 以
    及PI-S33-2 為首次自天然資源中分離出之化合物。此外,除pterocarpine 與angolensin 外,
    maackiain (1),medicarpin (7),liquiritigenin (9) 顯示具有類雌激素之作用。其他相關之活
    Based on the screening data of the extracts from Formosan plants and folk medicine by
    National Research Program, Pterocarpus indicus Willd. was found to be active toward cancer
    disease. The preliminary bioassay indicated that the methanol extract of the bark of P. indicus
    exhibited 52% inhibitory activity against ovarian cancer cells, Hela cells, at the concentration of
    50 μg/mL. In this year, a series of natural-occurring compounds, including 11 isoflavonoid
    compounds, 6 triterpenoids, and 6 steroids, were isolated and purified from the bark extract of
    this plant by column chromatography and high performance liquid chromatography (HPLC). The
    structures of all isolates were elucidated and characterized by spectral methods. Among them,
    compound 1 was isolated from the natural sources for the first time. Except for pterocarpine and
    angolensin, others were isolated from this plant fro the first time. In addition, maackiain (1),
    medicarpin (7), liquiritigenin (9) showed estrogen-like activity by the pER8-GFP reporter assay.
    Other bioactivities of these isolates are under investigation.
