Analysis of Pyrolysates from Four Herba Epimedii from Different Growing Areas

Abstract

Abstract: The pyrolysates of Herba Epimedii from four different growing areas were investigated by Pyrolysis-Gas Chromatography. The results indicated that 68, 48, 51 and 56 compounds were identified from the pyrolysates Herba Epimedii grown in Yunnan, Jilin, Liaoning and Sichuan, respectively, which were mainly phenols, ketones, aldehydes, alkenes, terpenoids and heterocyclic compounds. The most predominant compound was phenol (5%－8%) followed by cyclopenten-1-one, benzofuran, phenol derivatives, etc. The composition of pyrolysates of Herba Epimedii from four different growing areas was basically consistent, while the contents all identified compounds varied with growing areas. Greatly different lcariin contents were determined by HPLC in Herba Epimedii from Yunnan, Sichuan, Liaoning and Jilin, which were 5.49%, 12.85%, 1.95% and 2.82%, respectively.

Key words: Herba Epimedii, pyrolysis
