[Studies on the chemical constituents of Zanthoxylum dimorphophyllum Hemsl. var spinifolium Rhed. et Wils]
1College of Pharmacy, Second Military University, Shanghai 200433, China.
Aim:
To study the chemical components from the dried roots of Zanthoxylum dimorphophyllum Hemsl. var spinifolium Rhed. et Wils.
Methods:
Modern chromatography was used to isolate chemical components and the compounds isolated from Zanthoxylum dimorphophyllum Hems1. var spinifolium Rhed. et Wils were identified by various spectral methods.
Results:
Five compounds were isolated and identified as 6-(2',3'-dihydroxy-3'-methybutyl)-7-acetoxy-2H-1-benzopyran-2-one (I), 6-(2',3'-dihydroxy-3'-methybutyl)-7-(beta-D-glucopyranosyloxy)- 2H-1-benzopyran-2-one (II), hexacosanoci acid (III), aurepten (IV), 6-[6'-O-(-deoxy-alpha-L-mannopyranosyl)-beta-D-benzopyran-4-one (V).
Conclusion:
All of the above compounds were isolated from the plant for the first time, among them, I is a new compound.
