Abstract: The parishin contents in three variants of Gastrodia elata from southwest of China were determined.The results indicated that the contens of parishin were different among the different variants of G.elata from southwest of China.The contents of parishin A and parishin C of G.elata f. elata from Guangyuan in Sichuan province were 8.770 mg/g and 3.827 mg/g,respectively.G.elata f.glauca from Beichuan in Sichuan province had the highest contents of parishin B and parishin E with the value of 11.461 mg/g and 21.010 mg/g,which were extremely significantly higher than that of the other materials.The contents of parishin B and parishin E of three variants of G.elata fom Sichuan province were significantly higher than that of Yunnan and Guizhou province.However,the contents of parishin A and parishin C among three variants of G.elata from Yunnan,Guizhou and Sichuan province had no significant difference.Comprehensively,the parishin contents among variants of G.elata.from southwest of China were different.Of them,the parishin contents in G.elatafrom Sichuan province were the highest,but the parishin contents had no obvious relation to the variants.In total,the content of parishin of G.elata f. glauca from Beichuan in Sichuan province was the highest.
