Withanolide A is an important secondary metabolite in Withania somnifera, which is having a high medicinal value and possesses potent anti-tumor and antioxidant properties. Distribution of withanolide A in various organs of Withania somnifera was investigated by High Performance Liquid Chromatography (HPLC) method. The quantitative distribution of withanolide A was different in various organs t...

This study aimed to test the hypothesis that the aerial survival of the northern snakehead is involved not only with suprabranchial chamber respiration but also with physiological regulations. The aerial survival time and oxygen consumption rate (VO2) were determined in snakeheads with either normal or injured suprabranchial organs. Some hematological and biochemical parameters were assessed du...

A new monoterpene glycoside (1) isolated from the aerial part of Sibirae angustata RCHD. (Rosaceae) was found to be 1-O-beta-D-glucopyranosyl-geraniol-5,10-olide and named as sibiskoside. Acute toxicity study revealed that oral administration of 1 (2.5 g/kg body weight) to mice resulted in no death and no evidence of abnormalities in internal organs. Its oral administration to the mice reared w...

The study on aerial plant organs (leaves and stems) motions is reviewed. The history of observations and studies is put in the perspective of the ideas surrounding them, leading to a presentation of the current classification of these motions. After showing the shortcomings of such a classification, we present, following an idea of Darwin's, the various movements in a renewed and observation-ba...

Fifty three alkaloids were identified in the organs (roots, stems, leaves, flowers, and seeds) of Datura innoxia by GC/MS. Seventeen of them are reported for the first time for this species and one nor-derivative, 3-phenylacetoxynortropane (28), for the genus Datura. Furthermore, four new tropane esters were tentatively identified as 3-acetoxy-6,7-epoxytropane (acetylscopine) (10), 3-acetoxy-6-...

The application of agrochemical sprays to the aerial parts of crop plants is an important agricultural practice world-wide. While variable effectiveness is often seen in response to foliar treatments, there is abundant evidence showing the beneficial effect of foliar fertilizers in terms of improving the metabolism, quality, and yields of crops. This mini-review is focused on the major bottlene...

Anatomical structure of the common in forests and meadows Georgian subalpine zone plant - Aconitum nasutum Fisch. ex Reichenb underground aerial vegetative organs, rich diterpene alkaloids, was studied. A set diagnostic features has been established using accepted microtechnical methods. The conductive system axial organs A. nasutum, root, twig leaf stalk, a separated collateral structure. Casp...
