13. Comparisons of the active components in four unripe raspberry extracts and their activites
Abstract Dried unripe raspberry of Rubus chingii, were prepared as the following four extracts: unpurified raspberry extract (URE), purified raspberry extract (PRE), URE after high temperature-high pressure (UPE-H, HTHP), and PRE after HTHP (PRE-H). The total polyphenolic contents (TPCs) and total flavonoid contents (TFCs) of the four extracts, as assessed b

17. Leaves from the Tree Poincianella pluviosa as a Renewable Source of Antiplasmodial Compounds against Chloroquine-Resistant Plasmodium falciparum
Poincianella pluviosa is a tree whose stem bark is reputed to have antidiarrheal, wound healing, antitumoral and antimalarial properties. Considering that the leaves of the tree are a more abundant and renewable source than the stem bark, we chose to study the antimalarial potential of this organ part. The aqueous leaf extract exhibited a rich phenolic profi

18. Antiproliferative effect of urolithin A, the ellagic acid-derived colonic metabolite, on hepatocellular carcinoma HepG2.2.15 cells by targeting Lin28a/let-7a axis
An abnormality in the Lin28/let-7a axis is relevant to the progression of hepatitis B virus (HBV)-positive hepatocellular carcinoma (HCC), which could be a novel therapeutic target for this malignant tumor. The present study aimed to investigate the antiproliferative and anti-invasive effects of urolithin A in a stable full-length HBV gene integrated cell li

19. Preventive Effects of Ellagic Acid on Nucleus Tractus Solitarius Electrical Activity and Oxidative Stress Altered by Cerebral Global Ischemia/Reperfusion in Rat
ABSTRACT Cerebral ischemia commonly occurs when the blood flow to the entire brain or some part of the brain is disrupted. Global cerebral ischemia attenuates the nucleus tractus solitaries (NTS) EEG rhythm, increases the free radicals production and brain inflammation. Ellagic acid (EA) has antioxidative and anti-inflammatory effects against neural damages.

21. The role of condensed tannins in ruminant animal production: advances, limitations and future directions
ABSTRACT Tannins represent one of the most abundant polyphenolic compounds in plants. Tannins exist as a multitude of chemically unique entities in nature. The most commonly occurring tannins are typically divided into two major classes based on chemical structure: hydrolysable (HT) or condensed tannins (CT). Hydrolysable tannins are esters of gallic or ella

24. A cytotoxic C-glycosylated derivative of apigenin from the leaves of Ocimum basilicum var. thyrsiflorum
ABSTRACT The standardized 80% ethanolic extract of the leaves of Ocimum basilicum var. thyrsiflorum (L.) Benth., Lamiaceae, growing in KSA, exhibited a significant antioxidant activity compared to the ethyl acetate and butanol extracts, which was correlated to its higher phenolic and flavonoid contents. Chromatographic separation of the 80% ethanol extract r
