Abstract: Three new triterpenoid aglycones named Philinopgenin A (1), B (2), and C (3) were isolated from the acid hydrolysate of the crude glycoside mixture prepared from the whole sea cucumber Pentacta quadrangulasis Lesson. The corresponding structures were determined as 16β-acetoxyholosta-8(9), 24(25)-diene-3β-ol (1), 20, 25-epoxy-lanosta-9(11)-ene-3β-ol 18(16)–lactone (2) and 16β-acetoxyholosta-9(11), 24(25)-diene-3β-ol (3), respectively, on the basis of spectral evidence.
Keywords: Pentacta quadrangulasis Lesson; Philinopgenin A; Philinopgenin B; Philinopgenin C; triterpenoid aglycone
