Kaempferol, a flavonoid, contains plethora of therapeutic properties and has demonstrated its efficacy against cancer. This study aims to unravel the molecular targets that are being modulated by kaempferol on HeLa cells. Various assays were performed, namely: MTT assay, flow cytometry analyze DNA content quantitate apoptosis. Quantitative PCR protein profiling performed evaluate manifestation ...

−− The interactions between Bovine Serum Albumin (BSA) and three flavonols, galangin, kaempferol and quercetin were studied by means of fluorescence spectroscopy. The fluorescence intensity of BSA exhibits remarkable decrease along with appreciable blue-shift of its maximum emission wavelength upon addition of the three compounds, respectively. The respective binding constant Kα and number of b...

The ethyl acetate, chloroform extracts, and the two ‰avonoids kaempferol 1 and kaempferol-3-O-glucoside 2 isolated from whole plants of Thesium chinense Turcz were investigated for their antiin‰ammatory and analgesic activities. For the antiin‰ammatory activity, carrageenan-induced hind paw edema and xylene-induced mouse ear edema models, and for the analgesic activity, the acetic acid-induced ...

The flavonoids, kaempferol derivatives: 3-O-alpha-arabinofuranoside, 3-O-beta-glucopyranoside, 3-O-alpha-rhamnopyranoside, 3-O-alpha-rhamnopyranosyl (1 --> 6)-O-beta-glucopyranoside and quercetin derivatives: 3-O-alpha-arabinofuranoside, 3-O-beta-glucopyranoside, 3-O-alpha-rhamnopyranosyl (1 --> 6)-O-beta-glucopyranoside, were isolated from the flowers of Aesculus hippocastanum and identified. ...

A new flavone, named crotoncaudatin (1), was isolated from the stems of Croton caudatus Geisel. var. tomentosus Hook., together with nine known analogues: 3,5,6,7,8,3',4'-heptamethoxyflavone (2), tangeretin (3), nobiletin (4), 5,6,7,4'-tetramethoxy-flavone (5), sinensetin (6), kaempferol (7), tiliroside (8), kaempferol-3-O-rutinoside (9) and rutin (10). The structures of the above compounds wer...

Pathogenesis of chronic inflammatory diseases is associated with excessive elastase release through neutrophil degranulation. In the present study, inhibition of human neutrophil degranulation by four flavonoids (myricetin, quercetin, kaempferol, galangin) was evaluated by using released elastase as a biomarker. Inhibitory potency was observed in the following order: quercetin > myricetin > kae...

The follow-up of phytochemical and pharmacological studies of Sida rhombifolia L. (Malvaceae) aims to strengthen the chemosystematics and pharmacology of Sida genera and support the ethnopharmacological use of this species as hypotensive herb. The present work reports phytoconstituents isolated and identified from aerial parts of S. rhombifolia by using chromatographic and spectroscopic methods...

Kaempferol-3-O-gentiobioside, the major flavonoid glycoside in Indonesian Cassia alata was quantified in various parts of the plant. The mature leaf was found to contain the highest content of this metabolite. A decrease of the flavonoid content in the juvenile leaf during the period of October through December was also observed. The contents ranged from 2.0 to 5.0% and 1.0 to 4.0% in mature an...

Bioactive-directed fractionation of n-butanol extract from fresh fruits of Randia siamensis led to isolate of 4 new pseudoginsenoside compounds: pseudoginsenosides-RT2, -RT3, RT4 and -RT5, together with 7 known compounds: tyramine, pseudoginsenosides-RT1 methyl ester, pseudoginsenosides-RT1, pseudoginsenoside-RP1, kaempferol-3-O-β-D-xylose(1-2)-βgalactose, kaempferol-3-O-β-D-galactose, and 5-O...

The bioactive N-butanol fraction of the ethanol extract of the leaves of Cissus ibuensis was fractionated over silica Gel column to give Quercetin 3-O-rutinoside (I) and mixtures of Flavonoids (A2). A2 was fractionated using reverse phase HPLC to give Kaempferol 3-O-α-rhamnopyranosyl (1→6)-β-D-galactopyranoside (II), Kaempferol 3-O-rutinoside(III) and Kaempferol3-O-α-rhamnopyranosyl (1→6)-α-rha...
