ABSTRACT
Two new labdane diterpenes, 6alpha-malonyloxy-ethyl ester manoyl oxide and bis-6alpha-dioxymanoylmalonate, together with the known 6alpha-hydroxymanoyl oxide, 6alpha-malonyloxymaloyl oxide and betulinic acid were isolated from leaves of Stemodia trifoliata. Their structures were elucidated by spectroscopic studies (IR and HR-ESI-MS), including an extensive NMR (COSY, HSQC, HMBC and NOESY) analysis.
