Antioxidant activities and phenolic compounds of date plum persimmon (Diospyros lotus L.) fruits

Genetic variation among date plum (Diospyros lotus) genotypes in Turkey.

Turkey is one of the most important genetic resources of the date plum, Diospyros lotus, especially in the northeastern part of the country. Authenticating the identity of germplasm resources of D. lotus would be of great value for breeding. We examined the genetic variability of 11 D. lotus genotypes sampled from Coruh Valley in Turkey. One hundred and twenty-eight DNA markers were generated b...

Phenolic Compounds and In Vitro Antibacterial and Antioxidant Activities of Three Tropic Fruits: Persimmon, Guava, and Sweetsop

In our previous study, we have found that persimmon, guava, and sweetsop owned considerably high antioxidant activity and contained high total phenolic contents as well. In order to further supply information on the antibacterial and antioxidant activity of these three tropic fruits, they were extracted by 80% methanol. We then examined the extractions about their phenolic compounds and also st...

Comparative Studies of Antioxidant Activities and Nutritional Constituents of Persimmon Juice (Diospyros kaki L. cv. Gapjubaekmok)

The objectives of this research were to evaluate antioxidant activities and nutritional components, including phenolic acid, catechin, organic acid, sugar, and amino acid, of persimmon juice from persimmons grown in different regions around Korea. Persimmon (Diospyros kaki) exhibits potent antioxidant effects in DPPH, ABTS, reducing power, and FRAP methods of analysis. The levels of nutritional...

antioxidant activities and total phenolic contents of four apiacean fruits

Phenolic compounds and antioxidant activities of Liriope muscari.

Five phenolic compounds, namely N-trans-coumaroyltyramine (1), N-trans-feruloyltyramine (2), N-trans-feruloyloctopamine (3), 5,7-dihydroxy-8-methoxyflavone (4) and (3S)3,5,4'-trihydroxy-7-methoxy-6-methylhomoisoflavanone (5), were isolated from the fibrous roots of Liriope muscari (Liliaceae). Compounds 2-5 were isolated for the first time from the Liriope genus. Their in vitro antioxidant acti...
