| Abstract: | Objective:To fix the optimum collecting peroid of Asarum roots according to the content and mainconstituents of the volatile oil. Methods: With the different samples of Asarum heterotropode var.mandshuricum subterranean part, the content of the total voatile oil was determined by the method definedin the Chinese Pharmacopoeia, and the constituents of the voatile oil were analysed by GC-MS-DC (method).Results: The voatile oil of the subterranean part samples aged differently and collected in different period ofthe above plant were determined, and the data of the content of the total volatile oil and the relative content ofnine main constituentS in the oil of these subterranean part sapmles were obtained. Conclusion: Roots andrhizomes of Asarvm heterotropoides var. mandshuricum which have grown for over four years can be used asdrugs. The optimum collecting time is april, may and september. |
