Analyses of essential oil from Ferula sinkiangensis K.M.Shen / 中成药

ABSTRACT

AIM:To establish a qualitative fingerprint analysis with capillary GC. METHODS:HP-INNOWAX column(30 m?0.53 mm,1.0 ?m),column temperature90 ℃(15 min)4 ℃/min180 ℃(5 min)2 ℃/min200 ℃(3 min)10 ℃/min220 ℃(5 min),FID detector temperature230 ℃. RESULTS:Compared with reference peak of Sec-butyl-cis/trans-1-propentyl disulfide,17 common peaks on fingerprints of the oil from ferula sinkiangensis K.M.Shen were indicated by the method with satisfied stability,precision and repeatability. CONCLUSION:There are good similarities among 10 batches of essential oil from Ferula sinkiangensis K.M.Shen,and this method is reliable,simple and provides a reference standard for the quality control of Ferula sinkiangensis K.M.Shen.
