TLC determination of flavonoids from different cultivars of Allium cepa and Allium ascalonicum.
This study comprises the optimization and validation of a new TLC method for determination of flavonols in the bulbs of seven cultivars of onions and shallots. Separation was performed on RP-18 plates with the solvent mixture tetrahydrofuran/water/formic acid (40+60+6, V/V/V) as a mobile phase. The method was evaluated for precision, linearity, LOD, LOQ, accuracy and robustness. Chromatographic...
متن کاملAnticancer and anti-inflammatory activities of shallot (Allium ascalonicum) extract
INTRODUCTION Alliumplants are an important part of the diet of many populations and there is a long-held belief in their health-enhancing properties such as cancer prevention. In this study, the anticancer and anti-inflammatory activities of the aqueous extract of the Allium ascalonicum bulbs have been studied. MATERIAL AND METHODS The antiproliferative and anti-growth activity of the aqueous...
متن کاملTwo new phenylpropane glycosides from Allium tuberosum Rottler.
A phytochemical investigation of Allium tuberosum Rottler afforded two new phenylpropane glycosides, named tuberonoid A (1) and B (2), along with four known flavonoids, kaempferol 3-O-β-sophoroside (3), 3-O-β-D-(2-O-feruloyl)-glucosyl-7,4'-di-O-β-D-glucosylkaempferol (4), 3-O-β-sophorosyl-7-O-β-D-(2-O-feruloyl)glucosyl kaempferol (5), kaempferol 3,4'-di-O-β-D-glucoside (6). The identification a...
متن کاملAllimacrosides A-E, new steroidal glycosides from Allium macrostemon Bunge.
A new pregnane-type steroidal glycoside (1), two new spirostane-type steroidal glycosides (2, 3), and two new furostane-type steroidal glycosides (4, 5), named allimacrosides A-E, together with four known compounds (6-9) were isolated from a 80% MeOH extract of Allium macrostemon Bunge. The identification and structural elucidation of these compounds were based on their 1D- and 2D-NMR spectra, ...
متن کاملHeat stable antimicrobial activity of Allium ascalonicum against bacteria and fungi.
To study antimicrobial activity of shallot in comparison with that of garlic and onion against 23 strains of fungi and bacteria, water extracts of garlic, shallot and onion bulbs were prepared. Each extract was studied in different forms for their antimicrobial activity viz., fresh extract, dry extract and autoclaved extract. Minimal inhibitory concentration and minimal lethal concentrations of...
