The Structure of New Valepotriates from Tissue Cultures of Valeriana wallichii.
Colchicin-treated tissue cultures of VALERIANA WALLICHII produced besides the known valepotriates homovaltrate, isovaltrate, valtrate, acevaltrate and didrovaltrate several unknown substances of diene-valepotriate structure. Nine genuine valepotriates and two degradation products were isolated and their structure elucidated by means of their (13)C-NMR spectra.
