title: Triterpene constituents from the leaves of Melicope indica.
abstract: Phytochemical investigation of a petroleum ether extract of Melicope indica afforded two unusual pentacyclic triterpenes viz. neohop-13(18)-en-3alpha-ol (1) and fern-8(9)-en-3beta-ol (2) and the ubiquitous steroids, stigmasterol and sitosterol. The structures of 1 and 2 were independently elucidated on the basis of 2D NMR data and confirmed by comparison with those of related compounds. While compound 1 is a new natural product, this is the first report of occurrence of fern-8(9)-en-3beta-ol (2) from the genus Melicope.
