降香檀叶的非黄酮类成分研究

Non-flavonoid Constituents from the Leaves of Dalbergia odorifera

摘要:

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。

Abstract:

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 (3S)-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.
