livistona benthamii/抗氧化剂

Three new flavanes and eight known flavonoids were isolated from the fruits of Livistona chinensis. The structure of the new flavanes were established as 2S,3S-3,5,7,3',5'-pentahydroxyflavane (1), 2R,3R-3,5,6,7,8,4'-hexahydroxyflavane (2) and 2R,3R-3,5,6,7,8,3',5'-heptahydroxyflavane (3),

A new flavone glycoside tricin 7-O-β-glucopyranoside-2″-sulphate sodium salt along with 14 known flavonoid compounds were isolated and identified from the aqueous methanol extract of Livistona australis leaves. Their structures were established on the basis of extensive NMR (¹H, ¹³C, HSQC and H-H

This study investigated the antioxidative and obsteoblast differentiation promoting activity of the phenolics isolated from the 70% ethanol extract of the roots of Livistona chinensis. Two new phenolics, (2R,3R)-3,5,6,7,3',4'-hexahydroxyflavane (1), and phenanthrene-2,4,9-triol (2), together with

In this study, a high performance liquid chromatography-photo diode array detection-electrospray ionization tandem mass spectrometry (HPLC-DAD/ESI-MS) with pre-column DPPH assay is developed for screening the antioxidant components in the fruits of Livistona chinensis R. Br. Accordingly, six

Vitamin E, a potent antioxidant either present in the form of tocopherols and/or tocotrienols depending on the plant species, tissue and developmental stage, plays a major role in protecting lipids from oxidation in seeds. Unlike tocopherols, which have a more universal distribution, the occurrence

Cytological and physiological changes during cryopreservation were investigated in Livistona chinensis embryos excised 42 weeks after flowering. Both dehydration and freezing caused numerous cellular ultrastructural alterations. Dehydration seriously impaired plasma membrane integrity, while

Purpose: Discovering new antimyocardial ischemia drug candidates that are highly efficient, have low toxicity, and originate from natural products is a popular trend for new cardiovascular drug development at present. The ethanol extract of Livistona chinensis leaves showed a favorable

The hot water extract of the dry fruit of Chinese fan palm Livistona chinensis R Br. (LC) has been used in folklore medicine in Southern China for treating various tumors. Our in vitro study showed that the ethanolic extract (LCET) and the hot water extract (LCWE) of LC inhibited HL60 cell growth,

This study investigated the antioxidant and cytotoxic activity of the phenolics isolated from the fruits of Livistona chinensis. Four new compounds, 1-{ω-isoferul[6- (4-hydroxybutyl)pentadecanoic acid]}-glycerol (1), E-[6'-(5″-hydroxypentyl)tricosyl]-4-hydroxy-3-methoxycinnamate (2),
