Comparative study of differentiation levels and valepotriate content of in vitro cultures and regenerated and wild plants of Valeriana edulis ssp procera

Abstract

Valepotriate content levels in samples of in vitro cultures of Valeriana edulis ssp. procera were compared with those of roots and rhizomes of wild plants in the reproductive stage. Rhizomes and roots of regenerated and wild plants showed a similar valepotriate content. The data obtained support the hypothesis that valepotriate production in V. edulis spp. procera is closely related to rhizome and root differentiation. The large-scale propagation of this endangered plant may offer an attractive alternative for its production for medicinal purposes.
