“…However, phenolic compounds like sinapic, phytic acids and derivatives of flavonols (qucercetin) have been considered as potent antioxidant with antimicrobial, anti-inflammatory and anticancer properties by many workers 14,25,26 . It is speculated that the mechanism of flavonoid antimicrobial activity is due to their ability to inhibition of microbial adhesion and inactivation of cell envelope transport proteins 14 . Similarly, flavonoids also disrupt the fluidity of the microbial membranes 27 .…”

The antifungal efficacy of seed extracts (propanol, ethanol, methanol and sterile deionised water) of Camelina sativa cv. Calena (EC643910) against Rhizopus stolonifer was investigated by agar disc diffusion method. Among all extracts, methanolic seed extract (Disc 3) showed significant activity against R. stolonifer. However, no activity was observed against rest of the extracts (Disc 1, 2 and 4). The inhibition zones were ~35 mm for methanolic extract and ~41 mm for standard drug, respectively. The total phenol content was observed 13.5 µmol, 23.3 µmol, 42.9 µmol and 3.4 µmol gDW -1 in propanolic, ethanolic, methanolic and sterile deionised water extracts of Camelina, respectively. Likewise, the ascorbate peroxidase (APX) activity was observed highest in methanolic extract that was ~10.2, ~2.4 and ~5.7-folds higher as compared to propanolic, ethanolic and sterile deionised water extracts, respectively. Similarly, guaiacol peroxidase (GPX) activity was also observed highest in methanolic extract as compared to other extracts, which is ~7.3, ~1.9 and ~6.6-folds higher as compared to propanolic, ethanolic and sterile deionised water extracts, respectively. The findings of the study clearly speculate that the possibility of using methanolic seed extract of Camelina as a potential control measure against R. stolonifer, which may be used for the development of future herbal drug formulations.

Ninety-six species and hybrids of the genus Phaseolus and related genera, Dysolobium, Macroptilium, Strophostyles, and Vigna are surveyed for their leaf flavonoid (flavone/flavonol) aglycone and glucuronide distribution patterns. The aim is to determine whether the distribution patterns of certain flavonoid aglycones and/or glucuronides are restricted in each genus and hence, could be used to delineate the genus. The results show that flavonol aglycones (kaempferol and quercetin) are more frequent in the entire group than the flavones (luteolin and apigenin). Kaempferol is more prevalent than quercetin in the genus Macroptilium, while Strophostyles accumulates mainly quercetin. There is generally no restricted pattern for a particular type of flavonoid aglycone in Phaseolus and Vigna genera. Results also show the presence of flavonoid glucuronides in six out of 18 species of Phaseolus surveyed, but are absent in all the species of Vigna, Macroptilium, and Strophostyles. The situation in Dysolobium is inconclusive. A flavonoid band moved toward the anode during electrophoresis (a positive test for the presence of glucuronide) but glucuronic acid was not detected during subsequent analysis. In the genus Phaseolus, all the species and cultivars that accumulate flavones such as P. coccineus, P. ricciardianus and P. parviflorus accumulate flavone glucuronides, while P. vulgaris, P. tuberosus and P. zebra accumulate flavonol glucuronides.
