Methyl 3,4,5-trihydroxybenzoate (methyl gallate) was synthesized from 3,4,5-trihydroxybenzoic acid (gallic acid) by reaction with methanol in presence of sulphuric acid. gallate then reacted hydrazine monohydrate to give 3,4,5-trihydroxybenzohydrazide (galloyl hydrazide). The structure methyl and galloyl hydrazide characterized Fourier transforms infrared (FTIR) spectroscopy, mass spectrometry ...

The phytochemical study of flowering shoots of Caragana bungei Ledeb., Fabaceae, collected in Tuva Republic (Russian Federation) resulted in the isolation of sixteen compounds identified as β-sitosterol, β-sitosterol-3-Oglucoside, umbelliferone, kaempferol, quercetin, isorhamnetin-3-O-glucoside, isoquercitrin, rutin, narcissin, nicotiflorin, caffeic acid, 3-O-caffeoylquinic acid, 5-O-caffeoylqu...

the mineral contents of centaura leave and seeds were determined by inductively coupled plasma-atomic emission spectroscopy (icp-aes). macro element concentrations (p, k, ca, mg and s) of samples were found at high levels. k was established at high level in both leave and seed samples of centaurea. while k contents of leaves changes between 7254.10 mg/kg (centaurea lycaonica) and 26396.36 mg/kg...

Gallic acid is the starting material for hydrolysable tannin synthesis, but the mechanism of its formation in higher plants has not been known. To elucidate the pathway of gallic acid synthesis in the leaves of mountain birch (Betula pubescens ssp. czerepanovii), we studied the effects of glyphosate (N-[phosphonomethyl]-glycine) on the levels of individual hydrolysable tannins. Glyphosate is kn...

Hydrolysable polyphenols are present in Myriophyllum spicatum L. at high concentrations of up to 25% of dry matter and are also excreted. Bacteria associated with the submerged macrophyte M. spicatum isolated from the surrounding water column and epiphytic biofilm were tested for their ability to degrade polyphenols. Several bacterial isolates were capable of growing with tannic acid as the sol...

BACKGROUND Punica granatum (pomegranate), an edible fruit originating in the Middle East, has been used as a traditional medicine for treatment of pain and inflammatory conditions such as peptic ulcer. The numerous risks associated with nonsteroidal anti-inflammatory drugs (NSAIDs) for treatment of pain and inflammation give rise to using medicinal herbs as alternative therapies. This study aim...

Green tea is considered as a dietary source of antioxidant nutrients, which acts upon human health. Green tea leaves contain three main components in the form of simple hydroxy benzoic acids such as gallic acid, propyl gallate and xanthic bases (caffeine), have been reported to prevent or delay a number of degenerative diseases and act mainly upon the central nervous system and stimulating wake...

This study attempted to elucidate the neurotransmitter systems involved in the neurophysiological properties of ethanolic extract, fractions and pure isolates of Spondias mombin leaves in mice (n = 6) after intraperitoneal (i.p.) route of administration.The crude ethanolic extract of Spondian mombin leaves was fractionated using the partitioning method to obtain the ethylacetate, butanolic and ...
