Convolinine, a new alkaloid from convolvulus subhirsutus of uzbekistan flora

摘要

Several alkaloids of known structure and the new base convolinine were isolated from total alkaloids from the aerial part of Convolvulis subhirsutus growing in Uzbekistan. It has been established that convolinine is an N-hydroxyethyl derivative of convolvine and has the structure (±)-3α-(3,4-dimethoxybenzoyl)-Nhydroxyethylnortropane based on spectral data and an x-ray crystal structure.
