Rubescine Chemical Properties,Uses,Production

Description

A complex glucoalkaloid, this base also occurs in Adina rubescens. It is obtained as an amorphous, pale yellow powder which cannot be crystallized. It is laevorotatory having [α]25D - 121° (c 0.9, MeOH) and the ultraviolet spectrum in MeOH exhibits absorption maxima at 226, 275, 283, 289 and 328 mμ.. The alkaloid is characterized as the pentaacetate, m.p. l58-l6l °C.
