The fermented leaf of Ampelopsis grossedentata has been used as a beverage and folk medicine called "vine tea" in the southern region of China. In this paper, the optimum extraction conditions for the maximum recovery amounts of total flavonoids (TF), dihydromyricetin (DMY), myricitrin (MYG) and myricetin (MY) from natural Ampelopsis grossedentata leaves subjected to ultrasonic-assisted extract...

The use of many traditional medicinal plants is often hampered by the absence of a proper biochemical characterization, essential to identify the bioactive compounds present. The leaves from five species endemic to the Macaronesian islands with recognized ethnobotanical applications were analysed: Apollonias barbujana (Cav.) Bornm., Ocotea foetens (Ainton) Baill, Prunus azorica (Mouill.) Rivas-...

This study examines the effects of consensus and resulting organizational learning on new strategy implementation. In doing so, we consider two challenges inherent in implementing new strategy: breaking and reestablishing organizational and individual routines and managing uncertainties and unexpected problems. By sampling 113 groups within a large company, we found that group performance can b...

Research on neural correlates of consciousness has been conducted and carried out mostly from within two relatively autonomous paradigmatic traditions - studying the specific contents of conscious experience and their brain-process correlates and studying the level of consciousness. In the present paper we offer a theoretical integration suggesting that an emphasis has to be put on understandin...

A local herb, Kacip Fatimah, is famous amongst Malay women for its uses in parturition; however, its phytochemical contents have not been fully documented. Therefore, a study was performed to evaluate the phenolics, flavonoids, and total saponin contents, and antibacterial and antifungal properties of the leaf, stem and root of three varieties of Labisia pumila Benth. Total saponins were found ...

Raphanus sativus L., a small-sized red radish, is an important root vegetable crop found worldwide and is commonly used in salads. The objective of this study was to measure the total phenolic and flavonoid content as well as to evaluate the antioxidant activity of the ethanol extract of Raphanus sativus L. cv. Cherry Belle and Raphanus sativus L. cv. Valentine. The total phenolic content and t...

Background and objectives: Cancer cell resistance to common chemotherapy agents is on rise. Plants are considered valuable sources of herbal drugs for cancer therapy. The present study was conducted to investigate the in vitro antioxidant, anti-proliferative, and apoptosis-inducing properties of clove (Syzygium aromaticum L.) extract in human gastric carcinoma (AGS). Methods: Crude ethanol extr...

This study aimed to explore antiproliferative activity of aerial parts aqueous extract of Ampelocissus latifolia (Roxb.) Planch. (AAEAL). Antiproliferative activity of AAEAL was tested in root and/or shoot apical meristems of green gram and onion by analysing growth retardation and /or by scoring mitotic index, mitotic cell phase frequency. Phytochemical contents of AAEAL were detected and the ...

We assessed the polyphenolic contents and antioxidant potential of the aqueous, ethanol and methanol stem bark extracts of Jatropha curcas. The total phenol, flavonoids, flavonols and proanthocyanidin contents of the extracts were evaluated to determine their effect on the antioxidant property of this plant, using standard phytochemical methods. The antioxidant and free radical scavenging activ...
