BACKGROUND The role of natural products as a source for remedies has been recognized since the beginning of mankind. Nevertheless, a minority of folkloricly used medicinal plants have been evaluated for their pharmacological activities. OBJECTIVE The purpose of this study is to evaluate 33 selected

Natural product drug discovery programs often rely on the use of silica (Si) gel, reversed-phase media, or size-exclusion resins (e.g., RP-C18, Sephadex LH-20) for compound purification. The synthetic polymer-based sorbent Diaion HP20SS (cross-linked polystyrene matrix) is used as an alternative to

The O-methylation of various secondary metabolites is mainly catalyzed by S-adenosyl-l-methionine (SAM)-dependent O-methyltransferase (OMT) proteins that are encoded by the O-methyltransferase gene family. Citrus fruits are a rich source of O-methylated flavonoids that have a broad spectrum of

The in vitro cytotoxic activity on human cancer cell lines of sixteen commercial EOs such as Aloysia triphylla , Boswellia carterii , Boswellia serrata , Cinnamomum zeylanicum , Cistus ladanifer , Citrus × aurantium , Citrus limon , Citrus sinensis , Cymbopogon citratus , Foeniculum vulgare ,

Many natural products from plants have been identified to exert anticancer activity. It might be expected to be a challenge to look at the Saudi plants in order to discover new sources for new molecules which may have anticancer activity. The methanolic extracts of forty species of plants
