The risk created by infectious microorganisms to humans attracted the development of common medicine. To find an alternative source, medicinal plants with diverse metabolites play an important role in curing the diseases and human disorders caused by microbial pathogens. Medicinal plants namely, Citrullus colocynthis, Hyoscyamus muticus, Ocimum basilicum, Amaranthus lividus, Salvia aegyptiaca a...

OBJECTIVE To investigate the neuropsychopharmacological effect of a polyherbal formulation (PHF) on the learning and memory processes in rats. MATERIALS AND METHODS PHF contains Withania somnifera (Ashwagandha), Nardostachys jatamansi (Jatamansi), Rauwolfia serpentina (Sarpagandha), Evolvulus alsinoides (Shankhpushpi), Asparagus racemosus (Shatavari), Emblica officinalis (Amalki), Mucuna prur...

Tropane alkaloids, especially hyoscyamine (HYO) and scopolamine (SCO), are widely used in medicine for their antispasmodic, anticholinergic, and sedative properties. This study was undertaken to investigate the root and shoot tropane alkaloids production from in vitro shoot tip (as explant) culture of Hyoscyamus niger under different plant growth regulators including auxins (IAA, 2, 4-D, IBA, N...

Numerical taxonomy and seed storage protein analysis of Hyoscyamus species of Iran was carried out with the aim to illustrate species inter-relationship and to check the sub-generic taxonomic treatment proposed for the genus. Cluster analysis of morphological and protein data grouped the species in three separate clusters which supports the relationships of H. niger with H. reticulatus and H. k...
