Chemical investigation of the non-alkaloidal constituents of the leaves and stem bark of Kibatalia gitingensis (Elm.) woods. (Fam. Apocynaceae) Thelma A. Rivera. 89 leaves Available to the general public. Thesis (Master of Science in Pharmaceutical Chemistry)--University of the Philippines, 1981 The air dried leaves and stem bark of Kibatalia gitingensis (Elm.) Woods. yielded 0.18% and 0.41% respectively, on the dry basis, of identical mixtures of triterpenoids. The major triterpenoid was identified as α-amyrin acetate, m.p. 224-226(degrees C) and the minor triterpenoid as α-amyrin, m.p. 180-185(degrees C). These triterpenoid isolates were analyzed by TLC, color reactions, and spectroscopic methods. Further confirmation on their identifications was done by comparison with reference samples.
