Seasonal variations of the phytochemicals contents in needles of T. wallichiana var. mairei due to the effects of growth meteorological parameters were investigated in this study. The needles of T. wallichiana var. mairei were collected from different months and the contents of taxoids (paclitaxel, 10-deacetylbaccatin III (10-DAB), baccatin III, cephalomannine, 10-deacetyltaxol (10-DAT)), flavo...

Plants synthesize certain phytoconstituents for their protection, which, because they are not of primary need, are known as secondary metabolites. These secondary metabolites of plants, have often been found to have medicinal uses for human beings. One such gymnosperm having secondary metabolites of medicinal potential for humans is Taxus wallichiana (Himalayan yew). Besides being the source of...

BACKGROUND The present research was carried out to investigate pharmacological properties of Buxus papillosa C.K. Schneid. (Buxaceae). METHODS Buxus papillosa extracts of leaves (BpL), stem (BpS), roots (BpR) and BpL fractions: hexane (BpL-H), aqueous (BpL-A) also plant constituent, cyclomicrobuxine effect were studied in jejunum, atria, aorta and tracheal preparations from rabbit and guine-p...

Strychnos wallichiana (Loganiaceae) is a critically endangered medicinal plant, commonly used in several native medical practices. The majority of members of the Strychnos genus shares a similar chemical composition and contains common indole alkaloids. Purification of strychnine and brucine from a few species of Strychnos have already been reported; however, we have purified and quantified the...

Monoecy allows high plasticity in gender expression because the production of separate female and male flowers increases the ability to respond to specific environmental circumstances. We studied variation in sexual expression and its correlates in the monoecious shrub Buxus balearica, for two years, in six populations in the Balearic Islands and four in the Iberian Peninsula. Phenotypic gender...

! e analysis of the architecture of Buxus vahlii Baill. (Buxaceae) in western Puerto Rico is presented. Two populations growing in diff erent environmental conditions were studied: one is a coastal forest in the municipality of Rincón and the other is a mountain forest with karstic formations in the municipality of Isabela. ! e growth pattern in Buxus vahlii follows Champagnat’s model. Four sta...

Abstract Boxwood blight is caused by Calonectria henricotiae (Che) and C. pseudonaviculata (Cps). Unrecognized symptoms on Buxus cuttings used for propagation could potentially serve as a source of inoculum result in pathogen spread. In this study, boxwood (Buxus spp.) cultivars ‘Justin Brouwers', ‘Nana', ‘Green Beauty', Velvet' were assessed root production after exposure to 45 C (113 F) or 47...

Erratum In the original publication [1] the species name Kutki (Neopicrorhiza scrophulariiflora) is wrongly mentioned as CITES listed species. The correct version of the sentence in the second paragraph of “Threats and conservation challenges” can be found here: Illegal trade of NTFPs from the landscape often includes some of the CITES Appendix listed species such as Sunakhari (Orchids) and Lau...
