The methanol extract of the seeds of Turraea parvifolia has yielded seven novel triterpenoid derivatives: 12α-acetoxyazadironolide, turraparvin A (12α-acetoxy-7α,23-dihydroxy-24,25,26,27-tetranor-3-oxoapotirucalla-1,14,20(22)-trien-21,23-olide), turraparvin B (12α-acetoxy-7α,21-dihydroxy-24,25,26,27-tetranor-3-oxoapotirucalla-1,14,20(22)-trien-23,21-olide), turraparvin C (7α,12α-diacetoxy-21-hydroxy-24,25,26,27-tetranor-3-oxoapotirucalla-1,14,20(22)-trien-23,21-olide), 11- epi-21-hydroxytoonacilide, 11- epi-23-hydroxytoonacilide and turraparvin D (12α-acetoxy-7α-hydroxy-24,25,26,27-tetranor-3-oxoapotirucalla-1,14,20(22)-trien-21,23-lactam). The methanol extract of the seed of Turraea parvifolia has yielded 12α-acetoxyazadironolide, 11- epi-21-hydroxytoonacilide, 11- epi-23-hydroxytoonacilide and turraparvins A, B, C and D ( 1).
