This paper deals with the pharmacognosy of Hyptis suaveolens leaf including its morphological, anatomical, chemical constituents and powder analysis. Contrary to earlier reports, the leaves are amphistomatic. Stomata are diacytic, a few being isotricytic and ansiotricytic. Four types of trichomes have been noted. The venation is semicraspidodromous. Midrib consists of one large moon shaped and ...

As a defense mechanism of the leaves of Rhus javanica (Anacardiaceae) against the aphid Melaphis chinensis (Aphididae) attack, tannic acid is rapidly accumulated and forms galls along the midrib of the leaves resulting in a unique natural medicine Gallae Rhois. Tannic acid was found to inhibit the oxidation of L-3,4-dihydroxyphenylalanine (L-DOPA) catalyzed by tyrosinase (EC 1.14.18.1) with an ...

The hydrophobic cell wall polymer lignin is deposited in specialized cells to make them impermeable to water and prevent cell collapse as negative pressure or gravitational force is exerted. The variation in lignin subunit composition that exists among different species, and among different tissues within the same species suggests that lignin subunit composition varies depending on its precise ...

Rumen characteristics and digestive kinetics of brown midrib corn silage were evaluated with five late-lactation (221 DIM +/- 20 d) multiparous cows fitted with ruminal and duodenal cannula. Dietary treatments were applied by using a single reversal design with two 21-d periods where either brown midrib (BM3) or isogenic (ISO) corn silage were included in a total mixed ration formulated to be 4...

leaf anatomy of 27 species of potentilla l. (rosaceae), representing 9 sections and four related genera, especially tylosperma botsch., schistophyllidium (juz. ex fed.) ikonn., drymocallis fourr. ex rydb., and sibbaldia l. from iran were studied using light microscopy. the most outstanding characters of blade and midrib were measured. the result revealed a number of taxonomically important char...
