ABSTRACT
OBJECTIVE: To investigate the chemical constituents in the roots of Allium tuberosum. METHODS: Colum chromatography with different materials such as silica gel was used to isolate and purify the chemical constituents. Their structures were identified by spectroscopic analysis. RESULTS: Nine compounds were isolated from the roots of Allium tuberosum and their structures were identified as 4,8-dihydroxyacetophenone-8-O-ferulate(1), 4,8-dihydroxyacetophenone(2), 3,4,5-trimethoxybenzoic acid(3), 3,4,5-trimethoxycinnamic acid(4), buddlenol D(5), E-1,6,11-triene-4,5,9-trithiadodeca-9,9-dioxide(6), tianshic acid(7), daucosterol(8), and linoleic acid(9). CONCLUSION: Compound 1 is a new compound and compounds 2-5 are obtained from Allium tuberosumfor the first time.
