对药食两用植物南烛的化学成分进行了研究。利用大孔吸附树脂、反相硅胶柱色谱和制备型HPLC等色谱技术从南烛枝叶中分离得到11个糖苷类化合物,运用质谱、核磁等波谱技术鉴定其结构分别为10-O-反式对羟基桂皮酰-6α-羟基-二氢水晶兰苷(10-O-trans-p-coumaroyl-6α-hydroxyl-dihydromonotropein,1),10-O-顺式对羟基桂皮酰-6α-羟基-二氢水晶兰苷(10-O-cis-p-coumaroyl-6α-hydroxyl-dihydromonotropein,2),乌饭树苷(vaccinoside,3),10-O-顺式对羟基桂皮酰-水晶兰苷(10-Ocis-p-coumaroyl monotropein,4),异落叶松脂素-9-O-木糖苷(isolariciresinol-9-O-β-D-xyloside,5),鸢尾苷(tectoridin,6),vicenin-3(7),槲皮素-3-O-鼠李糖苷(quercetin-3-O-α-L-rhamnoside,8),槲皮素-3-O-阿拉伯糖苷(quercetin-3-O-α-L-arabinopyranoside,9),槲皮素-3-O-半乳糖苷(quercetin-3-O-β-D-galactopyranoside,10),槲皮素-3-O-葡萄糖醛酸苷(quercetin-3-O-β-D-glucuronide,11)。其中化合物1和2为新化合物,4,6,7为首次从该属植物中分离得到的已知化合物。
The chemical constituents of medicinal and herbaceous plants were studied. Eleven glycosides were isolated from the leaves of southern candelabrum using macroporous adsorption resin, reversed-phase silica gel column chromatography and preparative HPLC. Their structures were identified as 10-O-trans Hydroxy-cinnamoyl-6α-hydroxy-dihydromonotropein (1) 10-O-cis-p-coumaroyl-6α-hydroxyl-dihydromonotropein (2), vaccinoside (3), 10- Ocis-p-coumaroyl monotropein, 4), isolariciresinol-9-O-β-D-xyloside (5), tectoridin (6), vicenin-3 Quercetin-3-O-α-L-rhamnoside (8), quercetin-3-O- arabinopyranoside, 9), quercetin-3-O-β-D-galactopyranoside (10), quercetin-3-O -β-D-glucuronide, 11). Among them, compounds 1 and 2 are new compounds, while 4, 6 and 7 are known compounds isolated from this genus for the first time.
