红花八角茎叶中一个新的酚苷类化合物

A New Phenolic Glycoside from the Stems and Leaves of Illicium Dunnianum

  • 摘要:
    目的 对红花八角Illicium dunnianum Tutcher干燥地上部分的茎叶进行化学成分研究。
    方法 综合运用AB-8、硅胶、HW-40C、ODS、Sephadex LH-20和半制备HPLC等多种色谱学方法进行分离纯化,并根据化合物的理化性质和核磁共振波谱数据及ECD计算进行结构鉴定。
    结果 从红花八角茎叶70%乙醇提取物经HP-20大孔吸附树脂30%乙醇洗脱部位中共分离鉴定5个化合物,分别为茴香脑乙二醇-7-O-β-L-呋喃阿拉伯糖-(1→6)-β-D-葡萄糖苷(1)、苯甲醛-4-O-β-D-葡萄糖苷(2)、1-O-苯甲基-α-L-鼠李糖-(1→6)-β-D-葡萄糖苷(3)、1-O-苯甲酰基-β-D-葡萄糖苷(4)、Sachalinoside B(5)。
    结论 化合物1为新的酚苷类化合物,2~5为首次从该属植物中分离得到。

     

    Abstract:
    OBJECTIVE To study the constituents from the dried stems and leaves of Illicium dunnianum Tutcher.
    METHODS The compounds were isolated and purified by column chromatography of AB-8 macroporous resin, silica gel, HW-40C, ODS, Sephadex LH-20, and semi-preparative RP-HPLC. Their structures were elucidated by physicochemical properties, spectral analyses and ECD.
    RESULTS The 70% ethanol extract of Illicium dunnianum was subjected to AB-8 macroporous adsorption resin CC to yield 30% ethanol fraction. Five compounds were obtained and characterized as anisole glycol-7-O-β-L-funanarabifuranosyl-(1→6)-β-D-glucopyranoside (1), 4-O-β-D-glucopyranosyloxy-benzaldehyde (2), benzyl-O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside (3), β-D-glucopyranoside benzoate (4) and sachalinoside B (5), respectively.
    CONCLUSION Compound 1 is a new phenolic glycoside, 2-5 are identified from Illicium dunnianum for the first time.
