摘要

目的：对瑶族药消瘤藤Pileostegia tomentella的化学成分进行研究，以期能对其化学成分进行初步的阐明，促进其深入开发与利用。方法：采用溶剂提取法、萃取法、硅胶柱色谱法、重结晶法等方法对消瘤藤95%乙醇提取物进行分离和纯化，采用红外光谱法、质谱法、核磁共振法等现代波谱学方法对分离得到的化合物进行结构分析测试并鉴定。结果：从消瘤藤的95%乙醇提取物中分离得到9个化合物，通过波谱学方法鉴定为二十四烷酸（1），蒲公英赛醇（2），β-谷甾醇（3），3β-乙酰氧基-乌苏酸（4），豆甾烷-3，6-二酮（5），7-羟基-8-甲氧基香豆素（6），茵芋苷（7），7-羟基香豆素（8），3，4-二羟基苯甲酸（9）。其中7-羟基-8-甲氧基香豆素（6），茵芋苷（7），7-羟基香豆素（8）3个化合物为香豆素类成分。结论：化合物 1~9 均为首次在该植物中分离得到，该植物中富含多种香豆素类成分。该研究一定程度上对消瘤藤的化学物质基础进行了揭示，也能促进其定性定量质控手段的建立。

Abstract

Objective: To study the chemical constituents of Yao medicine Pileostegia tomentella

and promote its further development and utilization. Method: Solvent extraction method

silica column chromatography and recrystallization method were used to isolate and purify the chemical constituents of 95% ethanol extract from this plant. The structures of the obtained compounds were identified by infrared spectroscopy

mass spectrometry

nuclear magnetic resonance spectroscopy and other modern spectroscopic methods. Result: From the data of spectral analysis

nine compounds were obtained and identified as: n-tetracosanoic acid (1)

taraxerol (2)

β-sitosterol (3)

3β-acetoxy ursolic acid (4)

stigmastane-3

6-dione (5)

7-hydroxy-8-methoxycoumarin (6)

skimmin (7)

7-hydroxycoumarin (8)

and protocatechoic acid (9).Among them

compounds (6)

(7) and (8) were coumarins. Conclusion: Compounds 1-9 were isolated from this plant for the first time. It showed that coumarins were widely contained in this plant.
