Valeriana jatamansi is a high value perennial herb that grows at an altitude of 1000–3000 MASL in the Indian Himalayan Region and used Ayurvedic, Unani Chinese systems medicine. The plant extracts essential oil (EO) obtained from its roots are pharmaceutical, aromatic flavouring industries. On account global annual demand lack organized cultivation this herb, it mostly collected wild causing de...

The composition of the essential oil extracted from Valeriana hardwickii Wall. roots growing wild in Talle Valley of Arunachal Pradesh, Eastern Himalaya was analyzed by capillary GC and GC/MS. Thirty-one compounds representing 89.6% of the total oil were identified. The oil was found to be rich in sesquiterpenes from which oxygenated sesquiterpenes (25.7%). Methyl linoleate (21.1%) and Valerace...

Rat pheochromocytoma PC12 cells undergo neuronal differentiation in response to nerve growth factor. We show here that exposure of PC12 cells to Nardostachys chinensis glycoside induces the outgrowth of neurites, increases the activity of AChE, triggers cell cycle arrest in G1 and enhances the expression of growth associated protein 43 (GAP-43). Both the outgrowth of neurites and the increase i...

Three new iridoids, jatamanvaltrates R-S (1-2) and jatamanin Q (3), as well as three new sesquiterpenoids, valeriananoids D-E (4, 5) and clovane-2β-isovaleroxy-9α-ol (6), together with nine known compounds were isolated from the roots of Valeriana jatamansi Jones. Compound 2 was the first reported iridoid with fatty acid esters in the Valerianaceae family. The structures of new compounds were e...

A study was undertaken to develop a convenient, low cost, and an efficient technique for rapid propagation from aerial node of Valenaria jatamansi Jones directly in artificial soil formulations. The performance mediated emergence also evaluated higher altitude (HA) as well lower (LA) monitor the above below ground growth parameters year addition active marker component analysis. combination sup...
