Methanol 70% extract of Bauhinia racemosa aerial parts was tested for antimicrobial activity against different bacterial and fungal strains and for antioxidant activity and also total content of polyphenols with phytochemical analysis of the extract was determined. The results have showed that the extract has a significant antimicrobial activity, it inhibited the growth of Bacillus subtilis and...

Amygdalus persica L., belongs to Rosaceae family, and its flowers are used as medicine food. n-Butanol extract of A. were isolated purified with various column chromatographies, the fourteen compounds, chlorogenic acid butyl ester (1), rutin (2), protocatechuic (3), caffeic (4), 5-O-coumarroylquinic methyl (5), kaempferol-3-O-neohesperidoside (6), quercetin-3-O-β-D-glucoside (7), 3,5-dicaffeoyl...

givotia rottleriformis has been used in the indigenous systems of medicine for the treatment of inflammatory diseases like rheumatism and psoriasis. in order to evaluate this information, antipsoriatic activity of three flavonoids isolated from the ethanol extract of the bark of givotia rottleriformis were investigated using in-vitro and in-vivo model, namely rutin (i), luteolin-7-o-β-d-glucuro...

Pfaffia glomerata contains high levels of β-ecdysone, which has shown a range of beneficial pharmacological effects. The present study demonstrated that inflorescences of P. glomerata contain other important bioactive compounds in addition to β-ecdysone. The identification of compounds from inflorescences using liquid chromatography coupled with electrospray ionization tandem mass spectrometry ...

An investigation of the geopropolis collected by Melipona subnitida (jandaíra) stingless bee led to the isolation and characterization of two phenylpropanoids, 6-O-p-coumaroyl-D-galactopyranose (1) and 6-O-cinnamoyl-1-O-p-coumaroyl- β -D-glucopyranose (2), and seven flavonoids, 7-O-methyl-naringenin (3), 7-O-methyl aromadendrin (4), 7,4'-di-O-methyl aromadendrin (5), 4'-O-methyl kaempferol (6),...

Securigera varia (Fabaceae) is a common herbaceous perennial plant widely growing in Europe and Asia and purposely established for erosion control, roadside planting, and soil rehabilitation. The aim of this study was to determine the radical scavenging activity of a crude methanol extract of S. varia aerial parts by using the free radical DPPH (1,1-diphenyl-2-picrylhydrazyl) and to rapidly ide...

Solanum melongena is a member of genus that widely cultivated as fruit vegetable in Vietnam. According to Vietnamese traditional medicine, the fruits and whole plants are used treat toothache, turgescence, pruritus, haemorrhoids. As part our project study chemical composition bioactivity Vietnam, five flavonoid glycosides including kaempferol-3-O-β-D-glucopyranoside (1), isovitexin (2), kaempfe...

Two new acylated flavonol glycosides named kaempferol-3-O-(2-O-sinapoyl)-β-D-galactopyranosyl-(1 → 2)-β-D-glucopyranoside-7-O-α-L-rhamnopyranoside (1) and quercetin-3-O-(6-O-benzoyl)-β-D-glucopyranosyl-(1 → 3)-β-D-galactopyranoside-7-O-α-L-rhamnopyranoside (2), were isolated together with six known compounds from the seeds of L. sativum. Their structures were elucidated on the basis of spectros...

Rhagadiolus stellatus Gaertn., a Mediterranean member of the Cichorieae tribe of the Asteraceae family used as a food plant, was analyzed for its spectrum of phenolic compounds. Kaempferol 3-O-β-glucoside 1, kaempferol 3-O-β-rutinoside (nicotiflorin) 2, quercetin 3-O-β-glucoside 3, and luteolin 4 were isolated from the n-butanol layer of a methanolic extract of whole plants of Rh. stellatus of ...
