A New Dihomosesquiterpene, Termioic Acid A, from Curcuma aromatica

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 ( 1 H, 13 C, DEPT, 1 H– 1 H-COSY, HMQC, HMBC, and NOESY) sp...

Description
Summary: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 ( 1 H, 13 C, DEPT, 1 H– 1 H-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.
