Triterpenes from the Stems of Adinandra poilanei Gagnep.
Adinandra species have been utilized in Vietnamese folk medicine for the treatment of cancer, stomach aches and snake bite. From the stems of A. poilanei collected in Lamdong province, six triterpenes were isolated. Their chemical structures were determined as betulinal (1), betulin (2), 3β,20-dihydroxylupane (3), 1-oxo-erythrodiol (4), pirolonic acid (5) and betulinic acid (6). Compounds 3-5 were discovered from Adinandra genus for the first time.
Keywords: Adinandra poilanei, Betulin, 3β,20-dihydroxylupan, 1-oxo-erythrodiol, Pirolonic acid.
