降香檀叶的非黄酮类成分研究

Non-flavonoid Constituents from the Leaves of Dalbergia odorifera

为阐明降香檀(Dalbergia odorifera T. Chen)叶的化学成分,采用色谱分离方法,从叶的醇提和水煮液中得到8个非黄酮类化合物。经理化性质和波谱分析,分别鉴定为(3S)-6,7-二羟基-6,7-二氢芳樟醇(1)、淫羊藿次苷B1 (2)、淫羊藿次苷B6 (3)、淫羊藿次苷F2 (4)、苯甲醇β-巣菜糖苷(5)、苯乙醇β-巣菜糖苷(6)、2,3-丁二醇2-O-β-D-葡萄糖苷(7)和腺嘌呤(8)。化合物1为单萜、2和3为大柱香波龙烷糖苷、4～6为芳基糖苷、7为烷基糖苷、8为嘌呤,均为首次从该植物中报道。

To clarify the chemical constituents in the leaves of Dalbergia odorifera T. Chen(Leguminosae), eight non-flavonoid compounds were isolated from the ethanol extract and decoction of the leaves by means of chromatographic separation techniques. Based on spectral data, their structures were identified as(3 S)-6,7-dihydroxy-6,7-dihydrolinalool(1), icariside B1(2), icariside B6(3), icariside F2(4), benzyl alcohol β-vicianoside(5), phenethyl alcohol β-vicianoside(6), butane-2,3-diol 2-O-β-D-glucoside(7), and adenine(8). Compound 1 is a monoterpene, compounds 2 and 3 are megastigmane glucosides, compounds 4– 6 are aryl glycosides, compound 7 is an alkyl glucoside, and compound 8 is a purine. All the compounds were reported from this species for the first time.
