Abstract
Hoya lacunosa leaves contain some main C-glycosylflavonoids, which were identified as: 6-C- arabinosyl 8-C-glucosylapigenin (isoschaftoside), 6-C-glucosyl 8-C-arabinosylapigenin (schaftosi- de) and 6,8-di-C-arabinosylapigenin. In the latex triterpenols were found, often both free and in ester form, of which β-amyrin, α-amyrin, lupeol, 24-methylenecycloartanol, obtusifoliol and cycloeucalenol were identified in the free alcohol fraction. The esters, forming the major part of the total lipid fraction, were solely acetates of some of the above mentioned alcohols.Keywords
