The current research has centered on the use of pharmacological and binding affinity methods to test 36 compounds as bioactive constituents’ inhibitors for COVID-19. Six out phytoconstituents (rutin, quercetin, catechin gallate, rhamnetin, campesterol stigmasterol) have demonstrated outstanding molecular docking drug-like properties HIV Lopinavir Indinavir. Interestingly, lowest energies (LBE) ...

background: salvia limbata is an aromatic herbaceous plant and grows widely in iran turkey and afghanistan. in the previous study, six flavones together with rosmarinic acid were isolated from the ethyl acetate and methanol extracts of s. limbata. in this report, we focused on the isolation and identification of the glycosylated sterols and the main accumulated amino acid of the species s. limb...

The extracts of the stem bark of Calophyllum soulattri gave a new pyranocoumarin, soulamarin (1), together with five other xanthones caloxanthone B (2), caloxanthone C (3), macluraxanthone (4), trapezifolixanthone (5) and brasixanthone B (6) one common triterpene, friedelin (7), and the steroidal triterpene stigmasterol (8). The structures of these compounds were established based on spectral e...

background and objectives:wild sage(salvia macrosiphon boiss.) known as “marvak” in persian is one of the polymorphic and abundant plants of lamiaceae. the plants whole seeds usually soaked or boiled in hot water are widely used for inflammatory ailments in folk medicine. documents have shown that there is scant information on the chemical constituents of this plant seeds. the current study was...

A phytochemical study was conducted on the leaves of Phyllanthus reticulatus obtained from a riverside in Taman Negara Kuala Koh, Kelantan. The separations of the chemical components were carried out using different chromatographic techniques and structures of compounds were elucidated by spectroscopic methods including nuclear magnetic resonance as well as mass spectrometry. Three compounds we...

background: the genus lomatopodium fisch. & c.a.mey., belongs to apiaceae family and contains one herbaceous species growing wildly in iran. there are only a few papers about the chemical constituents of these plants. here, we focused on the isolation and identification of the main flavonoid glycosides and sterols from the aerial parts of l. staurophyllum, which has not been previously reported...

We have studied metabolism of plant sterols and squalene administered intravenously in the form of lipid emulsion mimicking chylomicrons (CM). The CM-like lipid emulsion was prepared by dissolving squalene in commercially available Intralipid. The emulsion was given as an intravenous bolus injection of 30 ml containing 6.3 mg of cholesterol, 1.9 mg of campesterol, 5.7 mg of sitosterol, 1.6 mg o...

In this study, the sterol contents of almond kernel oils collected from naturally growing almond trees in Mersin province were determined. Generally, the sterol contents of almond oil samples varied depending on almond types. The major sterols in almond oils wereß-sitosterol, 5-avenasterol and campesterol, followed by 5,24-stigmastadienol, stigmasterol, sitostanol, and cholesterol. W...
