Leaves of species the genus Juglans L. Juglandaceae family are promising types officinal medicinal plant materials, which preparations have an antimicrobial, restorative effect. In our opinion, contribution to antimicrobial activity, along with naphthoquinones, is also made by flavonoids contained in leaves various Therefore, there a need determine chemical composition using modern methods anal...

Despite public health risk mitigation measures and regulation efforts by many countries, regions, sectors, viral outbreaks remind the world of our vulnerability to biological hazards importance actions. The saltwater-tolerant plants in Salicornia genus belonging Amaranthaceae family are widely recognized researched as producers clinically applicable phytochemicals. contain flavonoids, flavonoid...

This paper describes the isolation of four phytoconstituents from the leaves of Bauhinia microstachya, a Brazilian medicinal plant used in folk medicine for the treatment of several ailments. Based on spectroscopic evidence, these compounds were identified as methyl gallate (1), kaempferol 3-O-rhamnosyl (2), quercitrin (3) and myricitrin (4). The crude methanolic extract and two compounds (3 an...

Two new flavonol glycosides, myricetin 4'-O-alpha-L-rhamnopyranoside (1) and quercetin 3'-O-alpha-L-rhamnopyranoside (2), together with a novel biflavonol compound, speciin (3), as well as eleven phenolic metabolites, namely myricitrin (4), europetin 3-O-alpha-L-(1)C(4)-rhamnopyranoside (5), quercitrin (6), hyperin (7), rhamnetin 3-O-beta-galacto-pyranoside (8), caffeic acid (9), caffeic acid m...

A Flavonoid glycoside compound, isolated and identified from E. polyantha as myricitrin, was analyzed a ligand for its molecular binding activity against SARS-CoV-2 protein (receptor domain on Spike/RBD, main protease/nsp5, EndoRNAse, RNA-dependent-RNA-polymerase/RdRp), receptor, ACE2, computationally assessed via docking method. This study aims to determine the potential of myricitrin in Indon...

Colorectal carcinoma is a leading cause of human mortality due to its high metastatic ability. Because the activation of matrix metalloproteinases (MMP) is a key factor in the metastatic process, agents with the ability to inhibit MMP activity have potential in the treatment of colorectal carcinoma. In the present study, among 36 flavonoids examined, myricetin was found to be the most potent in...

A new phenylbutanone glucoside, dorycnioside, was isolated from the methanol extract of the aerial parts of Dorycnium pentaphyllum subsp. herbaceum Vill. (Rouy) and identified as 4-(4'-O-beta-D-glucopyranosyl-3',5'-dimethoxyphenyl)-2-butanone (1). In addition, two known phenylbutanone glucosides, five flavonoids, one cyanogenic glucoside, one cyclitol and one hydroquinone glucoside were also is...
