Evaluating Korean rice genotypes and landraces for octacosanol contents and antioxidant activity.

Increase in the average life span and interest in correlation between food and human health have led to researches to find and utilise the functional materials in rice. Octacosanol in rice grain is well known for its potential benefit. This study was conducted to evaluate the Korean rice (Oryza sativa L.

Physico-chemical properties and cytotoxic potential of Cordyceps sinensis metabolites.

This study was conducted to estimate the antioxidant activities, biochemical properties and biological activities of one of the entomopathogenic fungi, Cordyceps sinensis. Analysis of fungal metabolites indicated that the most abundant free sugar was glucose; the highest component of organic acids was citric acid from 10-day culture medium and the glutamate was the predominant amino acid observed from 3-day culture medium. Maximum total polyphenols and flavonoids were detected in the 15-day culture medium.
