In Vitro Antioxidant and Anti-rhizopus Activity of Methanolic Seed Extract of Camelina Sativa L.

Abstract

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.

Catalysed-microwave based Pretreatment of Lignocellulosic Biomass of Camelina Sativa L. for Bio-Fuel Production

“…In India, it is a newly introduced for its potential commercialisation as bio-fuel crop. DIBER-DRDO, Haldwani is the pioneer agency in India to introduce this crop as alternate bio-fuel crop and also standardize its agro-technology in different climacteric zone of India for harnessing its potential as high quality renewable bio-fuel 20,21 . The cellulosic biomass of Camelina is an important resource of bio-fuel production.…”
