Alkaloids Isolated from Somatic Hybrid Cell Cultures of the Species CombinationRauwolfia serpentinaxrhazya stricta

Abstract The phytochemical analyses of a somatic hybrid cell suspension culture of the genus and species combination Rauwolfia serpentina x Rhazya stricta revealed a number of monoterpenoid indole alkaloids. The alkaloids were identified as tubotaiwine, an isomeric mixture of vallesiachotamine, stemmadenine and vomilenine and were all produced in small amounts < 2mg/litre cell suspension. The hybrid cells showed a greater diversity of alkaloid biosynthesis when compared with the parental cultures.
