Selection and micropropagation of high artemisinin producing clones of Artemisia annua L.
Results from unorganized callus cultures initiated from the leaves of the corresponding clones did not indicate the formation of artemisinin or related sesquiterpenes in these cultures. Expand
Antimicrobial and Cytotoxic Activity of the Extracts of Khat Callus Cultures
In the course of the work with khat tissue cultures, the production of dark colored pigments was observed as a typical characteristic of the callus culture, and the present investigation deals with the isolation, identification, and biological effects of such pigments. Expand
Quinone-methide triterpenes from tissue cultures of Catha edulis
Biotransformation of digitoxigenin by cell suspension cultures of Pergularia tomentosa and Ammi visnaga
In Vitro Propagation of Catha edulis

In vitro propagation of khat is described to provide reliable and uniform plant material for further studies on secondary plant products and to investigate its pharmacological properties. Expand
Enhancement of Somatic Embryogenesis and Production of Developmentally Arrested Embryos in Nigella sativa L.
Somatic embryogenesis of Nigella sativa was investigated with the objective of inducing and isolating somatic embryos for biosynthetic studies and developed into leafy structures on basal medium devoid of growth regula- tors. Expand
Studies on (−)-cathinone formation in micropropagated plants and tissue cultures of Catha edulis (Khat)
Callus growth was best obtained in the light on media containing 3.0 mg/1 IBA or NAA and the inclusion of 1.0 g/1 of PVP in the medium was found necessary to reduce the effects of pigments and to enhance callus growth. Expand
Catha edulis (Khat): In Vitro Culture and the Production of Cathinone and Other Secondary Metabolites
Khat, Catha edulis (Vahl) Forssk. ex Endl. (Celasteraceae), is an evergreen shrub or tall tree that may reach up to 25 m in height if not pruned (Fig. 1). Extensive pruning makes it a small shrub, as… 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
