Analysis of Volatile Components in Smilax Glabra Robx. and Its Adulterant / 中国药师

ABSTRACT

Objective: To analyze and compare the volatile components in Smilax glabra Robx. and its adulterant Smilax china L. . Methods: The volatile components in Smilax glabra Robx. and Smilax china L. were analyzed by head space solid phase micro-extraction (HS-SPME) combined with gas chromatography-mass spectrometry ( GC-MS). The relative percentage of each component was calculated by area normalization method. Results: Totally 24 components were detected out from Smilax glabra Robx. , and among them, 20 components were identified, which accounted for 97. 04% of the volatile components. Totally 21 components were detected out from Smilax china L. , and among them, 15 components were identified, which accounted for 77. 76% of the volatile components. Conclusion: The composition and content of volatile components in Smilax glabra Robx. and its adulterant Smilax china L. are differ-ent. The method can provide scientific basis for the identification of Smilax glabra Robx. and its adulterants.
