Valeriana wallichii (Family Valerianaceae), popularly named as Indian valerian, exists as three chemotypes. Aim of the study was to evaluate the effect of V. wallichii chemotype (patchouli alcohol) extract (DCME) and essential oil (VPAEO) on experimental models of nociception and to elucidate its possible mechanism of action. Analgesic effect was evaluated using acetic acid induced writhing and...

A new iridoid glucoside dimer (1) and a non-glycosidic iridoid (2) was isolated together with the known compounds, asperuloside (3), paederoside (4), daphylloside (5), citroside A (6) and benzyl 6-O-alpha-L-rhamnopyranosyl-beta-D-glucopyranoside (7), from the leaves of Lasianthus wallichii. The structures of the new compounds were elucidated by spectroscopic and chemical evidence.

The process of delayed wound-healing and unhealed wounds can cause serious problems to the patients. In this context it is revealed that scientists are looking for herbal treatment wounds, as remedy known having less or minimum undesired effects. Schima wallichii a lesser traditional medicinal plant used by certain section people in Assam, India healing agent; however, record on scientific vali...

Allium wallichii (A. wallichii) Kunth is considered one of the underutilised, threatened, and unexplored medicinal plant species having several beneficial health-promoting actions. Moreover, being so popularised in both ethnobotanical traditional systems, still, less studied terms proper pharmacognostic standardisation. The main objective current work to establish standard pharmacognostic, phys...

The title compound, C(14)H(11)NO(3), was isolated from the roots of Clausena wallichii. The carbazole ring system is approx-imately planar (r.m.s. deviation = 0.039 Å) and the dihedral angle between the two benzene rings is 4.63 (7)°. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked into a zigzag network extending parallel to the ac plan...

Bioassay-guided fractionation of a chloroform extract of Valeriana wallichii (V. wallichii) rhizomes lead to the isolation and identification of caffeic acid bornyl ester (1) as the active component against Leishmania major (L. major) promastigotes (IC50 = 48.8 µM). To investigate the structure-activity relationship (SAR), a library of compounds based on 1 was synthesized and tested in vitro ag...

Integration of WorldView-2 satellite image with small footprint airborne LiDAR data for estimation of tree carbon at species level has been investigated in tropical forests of Nepal. This research aims to quantify and map carbon stock for dominant tree species in Chitwan district of central Nepal. Object based image analysis and supervised nearest neighbor classification methods were deployed f...
