秃叶黄皮树果实中的三萜化学成分

目的：研究秃叶黄皮树（Phellodendron chinense var．glabriusculum Schneid）果实中的化学成分。方法：对秃叶黄皮树果实95％乙醇提取物的乙酸乙酯部分进行色谱分离，根据光谱数据和理化性质确定各化合物的结构。结果：分离得到8个已知化合物，分别为piscidinol A（1），phellochin（2），niloticin（3），dihydroniloticin（4），21，23-epoxy-21α，24，25-trihydroxytirucalla-7-en-3-one（5），2a，25-dimethylmelianodiol-（21R，23R）-epoxy-24-hydroxy-21a，25-methoxy]tirucalla-7-en-3-one（6），boujotinoloneA（7），3-ketooleanane（8）。结论：化合物5～8为首次从秃叶黄皮树分离得到。

Triterpenes from the Fruits of Phellodendron chinense Schneid var. glabriusculum Schneid

AIM： To investigate the chemical constituents from the fruits of Phellodendron chinense Schneid var. glabriusculum Schneid. METHODS： The constituents of ethyl acetate-soluble portions in the 95% ethanol extract were isolated and purified by various chromatographic methods. Their structures were identified by their physicochemical characteristics and spectral data. RESULTS： Eight known compounds were isolated and identified as piscidinol A（1）, phellochin（2）, niloticin （3）, dihydroniloticin （4）, 21, 23-epoxy-21α, 24, 25-trihydroxytirucalla-7-en-3-one （5）, 2a, 25-dimethylmelianodiol-（21R, 23R）-epoxy-24-hydroxy-21a, 25-methoxy]tirucalla-7-en-3-one （6）, boujotinolone A （7）, 3-ketooleanane（8）. CONCLUSION： Compounds 5-8 are isolated from Phellodendron chinense Schneid vat. glabriusculum Schneid. for the first time.
