Antimicrobial activity of extracts from the cell cultures of some Turkish medicinal plants

Antibacterial and antifungal effects of alcoholic extracts of 41 medicinal plants growing in Turkey

“…Most of the plants used for medicinal purposes have been identified, and their uses are well documented and described by different authors (Nadkarni 1876;Dastur 1985;Saradamma 1990), but the efficacy of many of these plants is yet to be verified. Natural plant extracts have also been tested in laboratories against bacteria and fungi (Sökmen et al 1999).…”

Antiherpetic activity of some endemic Hypericum species in Turkey

“…These differences for the anti-HSV activities between Hypericum species may be due to the compounds of the species responsible for the activity of antiviral, in particular whether hypericin do not contain pseodohypericin, the amount of these compounds and the time of collection of plant samples. Hypericin and pseudohypericin being responsible for the activity of antiviral compounds can be absent in some Hypericum species (for example, in Hypericum connatum) (Sökmen, 2001), if these compounds are present, the highest rate in the species including the period of flowering time can vary for collection time of the plants (Schmitt et al, 2001;Southwell and Campbell, 1991;Southwell and Bourke, 2001). In this research, although the presence of hypericin and pseudohypericin were not determined from plant samples, plant materials collected during the flowering period reported the highest proportion of containing these compounds.…”

Pharmacological profile of the aerial parts of Rubus ulmifolius Schott

“…This explains that the flavonoids rich extract may have cytotoxic constituents as well. This study justifies that the plant may be a potential source for isolation of anticancer bioactive molecules as there are reports that correlate simple bench‐top bioassays and human tumour cell cytotoxicities as potential antitumor agents [48, 49]. This needs for isolation of bioactive molecules as plants are good sources of anticancer drugs.…”
