Screening of Philippine plants for steroidal sapogenins


Anzaldo FE, Maranon J, Ancheta SF


Different parts of 83 local materials belonging to the families Leguminosae. Apocynaceae, Dioscoeaceae, Amaryllidaceae, Liliceae, Malvaceae, and Euphorbiaceae were extracted with 80 ethyl alcohol, 139 extracts were obtained and all were subjected to hemolysis test; 45 alcoholic extracts gave positive results. Positive samples were isolated for their crude sapogenin acetates. Adsorption chromatography using activated alumina as the adsorbing agent removed substances or resins which would react with the H2SO4 remaining in the sample. At the same time, it separated the monohydroxy from the dihydroxy sapogenins which made identification of steroidal sapogenins easier. Nineteen out of 48 that were isolated gave steroidal sapogenin spectral curves in the region of 200-400 in u. Some of these barks of Nerium indicum (adelfa), Jatropha curcas (tubang-bakod), Macaranga tanarius (binonga), and the tubers of Dioscorea hispida (nami). Plant samples investigated in the families Liliaceae, Amaryllidaceae, and Malvaceae were found to contain no steroidal sapogenins. (Author)
