Odorasides A and B, new sphingolipid glucosides from Klienia odora

Two new sphingolipid glucosides, odoraside A (1) and odoraside B (2), have been isolated from chloroform-soluble fraction of the total methanolic extract of Klienia odora, together with five known compounds, β-sitosterol (3), oleanolic acid (4), betulone (5), 2,3-dihydroxy-12-oleanen-28-oic acid (6), and β-sitosterol 3-O-β-d-glucopyranoside (7). Their structures were assigned from 1H and 13C NMR spectra, DEPT and by 2D COSY, NOESY, HMQC, and...
