As a rare endangered medical plant that newly cultivated,little experimental information is available for growth and metabolites of Tetrastigma hemsleyanum in response to nitrogen( N). The effects of different levels of N on growth of T. hemsleyanum and the content of phytochemicals(
OBJECTIVE
To study the optimum extraction technology of total flavonoids and total triterpenoids from Tetrastigma planicaule and their antioxidant activity.
METHODS
Optimized the extraction of total flavonoids and total triterpenoids using an L9 (3(4)) orthogonal array design, and the antioxidant
In this study, a novel polysaccharide TDGP-3 from Tetrastigma hemsleyanum Diels et Gilg was extracted by enzymolysis-ultrasonic assisted extraction (EUAE) method and its antioxidant and hypolipidemic activities were evaluated. With a molecular weight of 3.31 × 105 Da, TDGP-3 was composed
The phenolic profiles of Tetrastigma hemsleyanum leaf extracts by different solvents (80% methanol, ethyl acetate and hexane) and their antioxidant and antiproliferative activities were investigated. Thirteen phenolic compounds (3-caffeoylquinic acid, 5-caffeoylquinic acid, 1-caffeoylquinic acid,
Radix Tetrastigma (RT), a herbal medicine and functional food in China, showed strong antiproliferative activities in vitro. However, the effects and the underlying mechanism of phenolic-rich extract of RT in H22 tumor-bearing mice are still unknown. Thus, the phenolic profiles and
OBJECTIVE
To detect the in vitro total phenolics, flavonoids contents and antioxidant activity of essential oil, various organic extracts from the leaves of tropical medicinal plant Tetrastigma from Sabah.
METHODS
The dry powder leaves of Tetrastigma were extracted with different organic solvent
Ethyl Carbamate (EC), as a carcinogen widely found in fermented foods, was verified that its cytotoxicity was associated with oxidative stress. Polysaccharides from natural sources due to their antioxidative capacity have attracted great attention in the past time. In this study, purified
The effects of rare earth elements (REEs) not only on cell growth and flavonoid accumulation of Tetrastigma hemsleyanum suspension cells but also on the isoenzyme patterns and activities of related enzymes were studied in this paper. There were no significant differences in enhancement of flavonoid
Tetrastigma hemsleyanum is traditionally used as a folk medicine and functional food in China. Its extracts have been confirmed to have many bioactivities. However, the effect of extracting temperature on its bioactivity has not been reported. In this research, the total flavonoids content
Acrylamide (ACR), as a raw material of polyacrylamide that used in water purification, was verified to possess various toxicity. Tetrastigma hemsleyanum (TH) is a medicinal plant widely used to anti-inflammation and anti-tumor in Chinese folks. However, more researches focused on the biological
Tetrastigma hemsleyanum Diels & Gilg, a well-known traditional Chinese medicine, possesses antitumor and anti-inflammatory activity, etc. However, the anti-diabetic effect has not been determined. In our present study, a water-soluble polysaccharide, named THP with molecular weight of 93 307 Da, was
Since time immemorial, human beings have used various parts of plants in either prevention or treatment of ailments. Plants are rich sources of secondary metabolites such as alkaloids, steroids, terpenoids, flavonoids, and phenolic compounds with a high structural diversity. Many plants/herbs with
Ethnopharmacological relevance: Tetrastigma hemsleyanum Diels et Gilg (T.hemsleyanum), a rare herbal plant distributed in subtropical areas of mainland China, has become a focus of scientific attention in recent years because of its high
