Invitro and invivo cultivation of Pergularia tomentosa for cardenolides
The HPLC analysis of the extracts of both cultivated plants samples and calli from tissue culture experiments demonstrated promising results, and all extracts showed the presence of the major ghalakinoside, in variable concentrations. Expand
Cardenolide glycosides from root of Streptocaulon juventas.
Six cardenolides were isolated from the anti-tumor active fraction of the 75% ethanol extract of Streptocaulon juventas (Asclepiadaceae), mainly found in southwest of China, and 18 compounds were evaluated for their cytotoxicity against human lung A549 adenocarcinoma cell lines. Expand
Cytotoxic Cardenolides from Streptocaulon griffithii
A new cardenolide, 3‐O‐(β‐glucopyranosyl)acovenosigenin A (1), was isolated from the roots of Streptocaulon griffithii and found to be strongly cytotoxic against other human tumor cell lines, including A549, MCF‐7, and Hela cells. Expand
Pergularia tomentosa in Vitro Culture and the Production of Cardenolides and Other Secondary Metabolites
Asclepiadaceae, known locally as “Ghalaka” (Ibn El Bitar 1809), is a plant indigenous to Saudi Arabia, Egypt, Abyssinia, North Africa, Iran, Afghanistan, West Pakistan, northern and central Sudan. Expand
