Pergularia tomentosa L. (Daemia cordata Forssk, R. Br. ex Schult) Asclepiadaceae, known locally as “Ghalaka” (Ibn El Bitar 1809; Migahid 1989), is a plant indigenous to Saudi Arabia, Egypt, Abyssinia, North Africa, Iran, Afghanistan, West Pakistan, northern and central Sudan (Engler and Prantl 1891; Maire 1933; Migahid 1989). The plant is one of the abundant plants in Saudi Arabia, where it is found on rocky parts of deserts in various regions. 
Regeneration, Cardenolide and Flavonoid Production from In Vitro Cultures of Cynanchum acutum L. (Asclepiadaceae)
This represents the first report for regeneration from in vitro culture of C. acutum, as well as, the production of cardenolides and flavonoids from cultures to concentrations that are comparable to wild plants. Expand
Bioactivities and in silico study of Pergularia tomentosa L. phytochemicals as potent antimicrobial agents targeting type IIA topoisomerase, TyrRS, and Sap1 virulence proteins
Phytochemical quantification revealed that fruit and leaves extracts displayed great potential to become a potent antimicrobial agent and might be a promising source for therapeutic and nutritional functions and these phytocompounds could be further promoted as a candidate for drug discovery and development.

Cardenolides and ${\beta}$-Sitosterol Glucoside from Pergularia tomentosa L.
The aerial parts of Pergularia tomentosa L. afforded three cardenolides, desglucouzarin, coroglaucigenin and uzarigenin, in addition to β-sitosterol glucoside. The isolated compounds were identifiedExpand
Petunia hybrida : In Vitro Culture and the Production of Anthocyanins and Other Secondary Metabolites
Restriction fragment polymorphism analysis, using the chalcon isomerase A gene, indicates that the cultivar Violet 30 (V30), with which most of the described research is carried out, is most similar to the species P. axillaris and P. parodii. Expand
Pharmacognostical and Preliminary Phytochemical Investigation of the Fruit of Pergularia tomentosa L
The macro- and microscopical characters of the fruit of Pergularia tomentosa L., a plant with significant effect on the heart and blood pressure, are described. Expand
Alkaloid production by hairy root cultures in Atropa belladonna
The results show that the amount of the two alkaloids in the axenic cultures was the same as or even higher than those of normal plants grown in the field. Expand
Anthocyanin production of Glehnia littoralis callus cultures.
A stable callus line that produces anthocyanins was established from callus derived from a petiole of a Glehnia littoralis seedling and subcultured in the dark and the productivity has been sustained for 5 years. Expand
Effects of nutrients on anthocyanin production in cultured cells of Aralia cordata
Abstract Good results for anthocyanin production in dark-grown calli of Aralia cordata Thunb. were obtained on the addition of sucrose as the carbon source and NH4+ and NO3− at a molar ratio of 1:4Expand
Phytochemical and Biological Studies on Saudi Medicinal Plants Part 9. Antitumor Testing
Bioactivity in the form of 9KB or 9PS cytotoxicity, brine shrimp toxicity, toxicity to mice during 3PS testing, inhibition of crown gall tumors on potatoes, and for in vivo 3 PS antileukemic effects was detected in over 25 species which now are candidates for future bioactivity-directed fractionations.

Cardenolides in the regenerated plants obtained from Strophanthus divaricatus calli
Abstract The regenerated plants obtained from Strophanthus divaricatus calli contain 10 cardenolides, accumulating seven of them in the original plants. At
Anthocyanin synthesis in tissue cultures of Callistephus chinensis (China aster)
Callus cultures were derived from stems and leaves of 3 anthocyanin producing and 3 acyanic lines of Callistephus chinensis (Compositae). The tissue cultures of the cyanic lines were shown to produceExpand
