Induction of alkaloid diversity in hybrid plant cell cultures
1999
The treatment of Rauwolfia serpentina x Rhazya stricta somatic hybrid cell suspension culture with 100 μM of methyl jasmonate led to a general increase in indole alkaloid content and to qualitative changes in the alkaloid pattern. The content of Six alkaloids were investigated with respect to their content in both the cell biomass and nutrition medium. Intracellular 17-O-acetyl-norajmaline content on the 5th day after treatment had increased about 40-fold compared with the control culture. The respective concentrations of the other alkaloids increased by a factor of two to five. In total 26 indole alkaloids were identified in extracts of the methyl jasmonate-treated culture by TLC, UV, MS a…
Somatic Hybridization in the Family Apocynaceae (Catharanthus, Rauwolfia, Rhazya, and Vinca Species)
1994
The Apocynaceae family includes about 2000 species belonging to approximately 200 genera (Takhtadjan 1981). The majority of species originate in the tropics, only a few of them are common to Europe (Vinca minor, V. herhaceae, V. major, genus Trachomitum).
Alkaloids Isolated from Somatic Hybrid Cell Cultures of the Species CombinationRauwolfia serpentinaxrhazya stricta
1995
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.
