Abstract:
Objective:To analyze the volatile components in Violae herba and its mixed product Corydalis bungeanae herba, and distinguish Violae herba from Corydalis bungeanae herba. Methods:The volatile constituents in Violae herba and Corydalis bungeanae herba were extracted by solid phase micro-extraction(SPME),and then analyzed by GC-MS. Results:A total of 62 constituents were detected out,and among them,42 compounds were identified, which mainly were olefins, ketones and aldehydes. Totally 43 peaks were isolated from Violae herba,and among them,28 components were identified, which accounted for 66.93% of the total volatile oil. Totally 22 peaks were isolated from Corydalis bungeanae herba,and among them,17 components were identified,which accounted for 97.02% of the total volatile oil. Conclusion:The volatile components in Violae herba and its mixed product are different in their peak types of total ion chromatograms and chemical compositions with only three same components in total. The highest content of the volatile components in Violae herba is 2-pentanoyl furan (18.01%), and that in Corydalis bungeanae herba is 1-caryophyllene (46. 06%). This test method is fast and stable,which can be used to distinguish Violae herba from Corydalis bungeanae herba.
