VALEPOTRIATES IN TISSUE AND SUSPENSION CULTURES OF DIFFERENT VALERIANACEAE |
| Authors: | R. Schrall, H. Becker |
| Abstract:
Tissue cultures of nine different species of Valerianaceen plants have been initiated and maintained for at least one year: Valeriana officinalis L., V. wallichii DC., V. alliariifolia VAHL, V. sambucifolia MIK., Fedia cornucopiae (L.) GAERTN., Centranthus ruber (L.) DC., Valerianella dentata (L.) POLL., Valerianella coronata (L.) DC. and Valerianella locusta (L.) LATER. The tissue cultures have been derived from surface-sterilized stems or from aseptically grown seeds. The cultures were compared qualitatively and semiquantitatively for their valepotriate spectrum. The relative amount of valepotriates varied from species to species. Whereas in V. officinalis none of the five major valepotriates (valtrate, isovaltrate, didrovaltrate, acevaltrate, IVHD-valtrate) could be detected, all other cultures contained at least one of these substances. Fedia had a fairly high content of valtrate and didrovaltrate, in V. wallichii valtrate and acevaltrate were dominant. The highest content of acevaltrate could be found in Valerianella coronata. | |
