Abstract:
Objective: To compare the volatile compounds extracted from Rhodiola renulata respectively by HS-SPME and SD. Methods:The volatile constituents from Rhodiola crenulata were extracted respectively by HS-SPME and SD, and then the contents and the names were confirmed by GC-MS. Results:Totally 39 compounds were identified from Rhodiola crenulata by HS-SPME while 16 ones were identified by SD. Among them, 4 common compounds were detected. Conclusion: There are some differences between the two methods. Compared with SD, HS-SPME is obviously better because more volatile constituents can be extracted from the herb, furthermore, HS-SPME has notable advantages of higher retrieval matching and sensitivity.
