中文摘要: |
爬树龙(Rhaphidophora decursiva)地上部分用甲醇提取,利用硅胶柱层析、Sephadex
LH-20 柱层析和高效液相层析进行化学成分分离纯化,从中分离得到11 个化合物. 根据现代波谱
技术和理化性质对化合物结构进行鉴定,鉴定结构为:sesartemin(1)、(1R,2S,5R)-2-(3’-methoxy-
4’,5’-methylendioxyphenyl)-3,7-dioxa-6-oxobicyclo[3.3.0]octane(2)、6,7- 二甲氧基-4- 羟
基-1-萘甲酸(3)、原儿茶酸甲酯(4)、丁香酸(5)、1,2,4-三甲氧基苯(6)、原儿茶酸(7)、没食子酸
(8)、没食子酸甲酯(9)、胡萝卜苷(10)和β-谷甾醇(11). 其中化合物1-9 为首次从该属中分离得
到, 10、11为首次从该植物中分离得到. |
英文摘要: |
Eleven compounds are obtained by silica gel chromatography, Sephadex LH-20 chromatography and HPLC
from the aerial parts of Rhaphidophora decursiva in Yunnan Province. The chemical structures of these compounds are identified by modern spectroscopic analysis combined with their physico-chemical data. These compounds are identified to be
sesartemin (1), (1R,2S,5R)-2-(3’-methoxy-4’, 5’-methylendioxyphenyl)-3,7-dioxa-6-oxobicyclo[3.3.0]octane (2), 6,
7-dimethoxy-4-hydroxy-1-naphthoic acid (3), protocatechuic acid methyl ester (4), syringic acid (5), 1,2,4-trimethoxybenzene (6), protocatechuic acid (7), gallic acid (8), methyl gallate (9), daucosterol (10) and β-sitosterol (11). Among them, 1-9
are obtained from the genus Rhaphidophora for the first time, and 10 and 11 are isolated from R. decursiva for the first time. |
