Dammarane glycosides from aerial parts of Neoalsomitra integrifoliola

From the aerial parts of Neoalsomitra integrifoliola, a new 20,24-epoxydammarane triterpene and 11 new glycosides were isolated along with a known cucurbitacin glycoside, seven known cucurbitacins and neoalsoside A. The latter compound has previously been isolated from the rhizomes of this plant. The structures of the new compounds have been established by spectroscopic and chemical means.
