REASONS FOR PERFORMING STUDY It is hypothesised that European atypical myopathy (AM) has a similar basis as seasonal pasture myopathy in North America, which is now known to be caused by ingestion of hypoglycin A contained in seeds from the tree Acer negundo. Serum from horses with seasonal pasture myopathy contained the conjugated toxic metabolite of hypoglycin A, methylenecyclopropyl acetic a...

Some insects use host and mate cues, including odor, color, and shape, to locate and recognize their preferred hosts and mates. Previous research has shown that the Asian longicorn beetle, Anoplophora glabripennis (Motschulsky), uses olfactory cues to locate host plants and differentiate them from non-host plants. However, whether A. glabripennis adults use visual cues or a combination of visua...

Nutrient resorption from senescing leaves is a key mechanism of nutrient conservation for plants. The nutrient resorption efficiency is highly dependent on leaf nutrient status, species identity and soil nutrient availability. Nitrogen is a limiting nutrient in most ecosystems, it is widely reported that nitrogen resorption efficiency (NRE) was highly dependent on the soil nitrogen availability...

The mechanism of Methylene Blue adsorption on acid activated carbon Vitex Negundo Stem (AAVNS) has been studied through batch experiments. Generally, dyes are organic compounds used as coloring products in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the industry. In this study, Vite...

Xanthine oxidase inhibitory activity has been reported from different plants such as Cinnamomum cassia, Chrysanthemum indicum, Lycopus europaeus, Polygonum cuspidatum, Acacia confuse, Coccinia grandis, Datura metel, Strychnos nux-vomica, Vitex negundo, Coccinia grandis, Vitex negundo, Fraxinus angustifolia, Pistacia lentiscus, Hyptis obtusiflora, H. lantanaefolia, Artemisia vulgaris, Caesalpini...

Nutrient management has increasingly become important in producing quality medicinal plant materials. Vitex negundo is an perennial widely distributed tropical Asia and Africa. This study aimed to examine the effects of nitrogen (N) phosphorus (P) fertilization on biomass, polyphenol contents, essential oil yield composition field cultivated V. negundo. Two experiments were conducted; one was p...

Understanding the responses of riparian trees to water availability is critical for predicting the effects of changes in precipitation on riparian ecosystems. Dioecious Acer negundo L. (box elder) is a common riparian tree that is highly sensitive to water stress. Earlier studies indicated that the genders of A. negundo respond differently to water availability, with males being more conservati...

The present study investigated the effect of the various fractions of hydromethanolic extract of the leaves of Vitex negundo (Verbenaceae) against ethanol-induced cerebral oxidative stress in rats. Cerebral oxidative stress was induced by the administration of 20% ethanol (5 ml/100 gbw) for a period of 28 days. The petroleum ether (PEF), chloroform (CF), ethylacetate (EAF) and residual (RF) fra...
