Chemical Constituents of the Ethyl Acetate Extract from Diaphragma juglandis Fructus and Their Inhibitory Activity on Nitric Oxide Production In Vitro.
Diaphragma juglandis fructus contains various bioactive constituents. Fourteen compounds were isolated from Diaphragma juglandis fructus by preparative high performance liquid chromatography (pre-HPLC) and high-speed counter-current chromatography (HSCCC). Their structures were identified by nuclear magnetic resonance (NMR) and electrospray ionization mass spectrometry (ESI-MS). Compounds (+)-d...
متن کاملChemical constituents isolated from Polygala japonica leaves and their inhibitory effect on nitric oxide production in vitro.
A methanolic extract of dried leaves of Polygala japonica Houtt (Polygalaceae) significantly attenuated nitric oxide production in lipopolysaccharide-simulated BV2 microglia. Five anthraquinones chrysophanol (1), emodin (2), aloe-emodin (3), emodin 8-O-beta-D-glucopyranoside (4) and trihydroxy anthraquinone (5), and four flavonoids kaempferol (6), chrysoeriol (7), kaempferol 3-gentiobioside (8)...
متن کاملAntitumor and apoptotic activities of the chemical constituents from the ethyl acetate extract of Artemisia indica.
Cancer is one of the most eminent diseases of modern times and numerous natural products derived from medicinal plants have been identified as potential sources of antitumor drugs. A successful anticancer drug must target or inhibit tumor cells whilst causing minimal damage to healthy cells. The present study aimed to investigate the antitumor efficacy of ethyl acetate extract, and other isolat...
متن کاملstudy the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
15 صفحه اولChemical constituents of the ethyl acetate extract of Belamcanda chinensis (L.) DC roots and their antitumor activities.
An activity-directed fractionation and purification process was used to isolate antitumor compounds from the roots of Belamcanda chinensis (L.) DC. The ethyl acetate extract showed greater antitumor activities than the other extracts, consequently leading to the isolation of 18 compounds identified as β-sitosterol (1), dausterol (2), quercetin (3), kampferol (4), shikimic acid (5), gallic acid ...
