title: Cucurbitane, hexanorcucurbitane and octanorcucurbitane glycosides from fruits of Trichosanthes tricuspidata.
abstract: From the fruits of Trichosanthes tricuspidata, 14 cucurbitane glycosides (khekadaengosides A-J, M-N, cucurbitacin J 2-O-beta-glucopyranoside and cucurbitacin K 2-O-beta-glucopyranoside), a hexanorcucurbitane glucoside (khekadaengoside K) and octanorcucurbitane (khekadaengoside L) were isolated along with two known cucurbitane glucosides (cucurbitacin 2-O-beta-glucopyranoside and 25-O-acetyl-cucurbitacin 2-O-beta-glucopyranoside). Structural elucidations were based on chemical and spectroscopic analyses.
