The aim of this work was to evaluate the spectrophotometric methodology for determining the total flavonoid content (TFC) in herbal drug and derived products from Bauhinia monandra Kurz. Several analytical parameters from this method grounded on the complex formed between flavonoids and AlCl₃ were evaluated such as herbal amount (0.25 to 1.25 g); solvent composition (ethanol 40 to 80%, v/v); as...

BACKGROUND Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) is a surface sensitive mass spectrometry technique with potential strengths as a method for detecting enzymatic activity on solid materials. In particular, ToF-SIMS has been applied to detect the enzymatic degradation of woody lignocellulose. Proof-of-principle experiments previously demonstrated the detection of both lignin-d...

The present article describes the chemical characteristics such as pH of aqueous extract, fluorescence, aqueous and alcoholic extractives, lignans and TLC profile of aqueous extract of Bhuiavli (Phyllanthus niruri).

There are few data on fine root biomass and morphology change in relation to stand age. Based on chronosequences for beech (9-140 years old), oak (11-140 years) and alder (4-76 years old) we aimed to examine how stand age affects fine root biomass and morphology. Soil cores from depths of 0-15 cm and 16-30 cm were used for the study. In contrast to previously published studies that suggested th...

Abstract Taiwania ( cryptomerioides Hayata) has long been regarded as a living fossil from the Tertiary period of Mesozoic Era for its distinguished yellowish-red color with purplish-pink streaks presented in heartwood. With this elegant appearance that matches “red” good fortune Taiwanese culture, is supposed to be popular wood Taiwan where it native species of. Extractives contribute properti...

Aqueous (hydrophilic) and chloroform (Lipophilic) extracts of nine medicinal plants currently used in traditional medicine, in Egypt, to treat some gastrointestinal tract (GIT) disorders were tested for their gastro-protective effect against the incidence of peptic ulcer. Indomethacin-induced ulcer in a rat model was used for this testing. Mentha microphylla, Brassica oleracea Capitata (Cabbage...
