摘要
The naturally occurring C17 compound dihomosesquiterpene (1), along with two known compounds (2, 3), was isolated from the ethanolic extract of Curcuma aromatica rhizomes. Compound 1 was identified as a new compound using 1D and 2D NMR (H-1, C-13, DEPT, H-1-H-1-COSY, HMQC, HMBC, and NOESY) spectroscopic techniques and called termioic acid A ((1S, 4S, 5R, 6S, 8E, 10Z)-1,13-dihydroxy-4-epoxy-8(12),9(10)-diene-termi-11-oic acid). With the help of HPLC, the content of compound 1 in the extract was also determined.
