The phytochemical constituents, quantitative antioxidant, and total phenolic content of Hardwicikia binata Roxb. plant parts were investigated in the present study. Methanolic extracts of H. binata leaves and stems were obtained using the traditional extraction methods, soxhlet and maceration. Preliminary tests for phytochemicals, revealed the presence of flavonoid, steroids, tannin and terpenoids, tannins in the stem and, flavonoids and phenols in the methanolic extracts of the stem and leaves, respectively. Saponin was found in the leaves and stem parts, but no alkaloids were identified in e

Abstract:

The growing interest in fermented dairy products is due to their health-promoting properties. The use of milk kefir grains as a starter culture made it possible to obtain a product with a better nutritional and biological profile depending on the type of milk. Cow, buffalo, camel, donkey, goat, and sheep milk kefirs were prepared, and the changes in sugar, protein, and phenol content, fatty acid composition, including conjugated linoleic acids (CLAs), as well as antioxidant activity, determined by ABTS and FRAP assays, were evaluated and compared.

Abstract:

Two species of bamboo, Phyllostachys edulis and Phyllostachys aureosuleata (including 4 cultivars for each of the species) are known to have significant amounts of phenols and flavonoids, and exhibit a strong antioxidant activity. Experiments were conducted to examine the variation in the contents of total phenols and flavonoids, and antioxidant activities in the shoots and shells. The result showed that the hightest contents of total phenols and total flavonoids were P. aureisykeata cv. Spectabilis and P. edulis cv. Heterocycla, respectively.
