*In plants, epigenetic variations based on DNA methylation are often heritable and could influence the course of evolution. Before this hypothesis can be assessed, fundamental questions about epigenetic variation remain to be addressed in a real-world context, including its magnitude, structuring within and among natural populations, and autonomy in relation to the genetic context. *Extent and ...

The paper deals with the detailed pharmacognosy of the whole plant of Orilaitamarai (Hybanthus enneasperms) sold in the local market under the name Purusharatna, Ratanpursuha. The studies include macro, microscopical, histochemical and diagnostic characters of the root, stem and leaf. The physical constants, fluorescence characteristics and chromatographic studies of the whole plant are also pr...

In order to continue our previous studies on some Viola species from Romania, we have analysed for the first time some active principles from aerial parts of V. declinata Waldst. et Kit. We have performed gravimetric methods for saponins and mucilages, and spectrophotometric determinations and HPLC analysis of carotenoids. We established the content in saponins (4.40%), mucilages (10.26%), and ...
