Research ArticleOpen accessPhrase in the titleIsolation and Characterization of Chemical Constituents, Cytotoxicity, Antibacterial and Antioxidant Activity of the Compounds from Leptadenia hastata Roots Extract ByIsaac John Umaru, Hauwa A. UmaruThe aim of this work was to extract, isolate and characterise the chemical constituent from Leptadenia hastata roots. Fresh roots were washed and dried and was subjected to sequential maceration in polar and non-polar solvents. And introduced into rotary evaporator to concentrate the extract. Isolated compound was subjected to Thin Layer Chromatography and spectral analysis such as column and UV-Visible … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 4 · 24 Dec 2019 · 7,959 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleAnticancer Activity of Isolated Chemical Constituents from Miliusa smithiaeChonthicha Naphong, Wilart Pompimon, Punchavee SombutsiriMiliusa plants belonging to the family Annonaceae are found in Thailand and have been used as Thai traditional medicines. There have been a few previously reports on the chemical constituents of plants in this genus, describing the presence of aporphine alkaloids, terpenoids, flavonoids, phenylpropanoids, styrylpyrones, bis-styryls and homogentisic acid derivatives. Miliusa smithiae, a new species for Thailand and world, has … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,259 accessesView PDFCite
Research ArticleOpen accessIn the abstractComputational Validation of Selected Compounds from the GC-MS Profile of Abies numidica Essential Oil and their Antibacterial EffectsAbdelouahab Dehimat, Boudjellal Fayssal, Salem Dounya et al.This work examined the chemical composition of the Algerian endemic tree Abies numidica (Pinaceae) and investigated the antibacterial potential of three major constituents of its essential oil-Santene, Linalyl acetate, and 2,6-Octadiene-2,6-dimethyl-as reported in previously published GC-MS data. Computational antibacterial screening was carried out by docking the selected compounds onto the bacterial proteins 5Z9N (Staphylococcus aureus) and 3AQC (Micrococcus luteus).
