Michael Whitehouse (Prof) Griffith University Medical School Qld Australia. Pharmacognosy Communications,2013,3,4,86-96.DOI:NilPublished:December 2013Type:The Janus Corner ABSTRACT This occasional section within the journal surveys visions and achievements, often not on the main track of the developing biomedical sciences, but all relating to discoveries and developments of medicinals – both ancient and modern. What they have in common, in one way or another,is providing further background and glances around the edges of the core discipline of pharmacognosy, as it has been and continues to evolve within our times.Read more.., Download PDF

Pharmacognosy Communications,2013,3,3,02-11.DOI:10.5530/pc.2013.3.2Published:August 2013Type:Review Article ABSTRACT The family Apocynaceae consists of tropical trees, shrubs and vines. Characteristic features of the family are that almost all species produce milky sap. Leaves are simple, opposite or whorled; flowers are large, colourful and slightly fragrant with five contorted lobes; and fruits are in pairs. With the inclusion of species of Asclepiadaceae, the family has now enlarged from two to five sub-families.…

Pharmacognosy Communications,2013,3,3,12-15.DOI:10.5530/pc.2013.3.3Published:August 2013Type:Research Article ABSTRACT Three alkyl coumarates (hexadecyl coumarate, eicosyl coumarate and docosyl coumarate) and five alkyl ferulates (tetradecyl ferulate, pentadecyl ferulate, heptadecyl ferulate, octadecyl ferulate and nonadecyl ferulate) could be tentatively detected in the partially purified HPLC fraction of Ipomoea carnea subsp. fistulosa by high resolution electrospray ionization mass spectroscopy (HRESIMS). This is in addition to octadecyl p-coumarate whose detailed structure elucidation, antifungal activity and isomerization have already been reported. The compounds were compared with alkyl coumarates and alkyl ferulates reported from other…

Pharmacognosy Communications,2013,3,3,16-21.DOI:10.5530/pc.2013.3.4Published:August 2013Type:Research Article ABSTRACT Background: Seeds of Asteracantha longifolia Nees. (Acanthaceae) are an important ingredient in many traditional/herbal formulations used in the management of a wide range of reproductive disorders. They are reported to posses various therapeutically active phytochemical constituents like asteracanthine, lupeol, asterol, β-sitosterol etc. Materials and Methods: In this research work, seeds collected from various geographical regions were analyzed using two chromatographic techniques (HPTLC and HPLC). A comparative evaluation of β-sitosterol content in respective samples using these techniques has been…

Materials and Methods: The total phenolic and flavonoid content of CDEE was determined using standard curve of gallic acid and quercetin respectively. In vitro antioxidant activity was determined by 2,2-diphenyl-1-picryl hydrazyl (DPPH) and 2,2’-azino-bis (3-ethylbenzo-thiazoline-6-sμlfonic acid) diammonium salt (ABTS) radicals…

This has triggered search for anti-infective agents from natural products and alternative modes of antifungal therapy. Objective: The aim of this study was to evaluate in vitro antifungal activity of oil of Cymbopogon citratus and its major active compound citral alone and in combination with fluconazole against azole-resistant strains of Aspergillus spp and Trichophyton…
