Screening and GC-MS profiling of ethanolic extract of .

Medicinal plants are boundless source of raw materials for the pharmaceutical. Identification of natural compounds from medicinal plant is helpful in the discovery of novel therapeutic agents. Tylophora pauciflora is a medicinal plant, which possess many biological activities such as antioxidant activity, anti-inflammatory activity and anti cancer activity.

Chemosensing of honeybee parasite, Varroa destructor: Transcriptomic analysis.

Chemosensing is a primary sense in nature, however little is known about its mechanism in Chelicerata. As a model organism we used the mite Varroa destructor, a key parasite of honeybees. Here we describe a transcriptomic analysis of two physiological stages for the Varroa foreleg, the site of primary olfactory organ.

Isolation, structural characterization and in silico drug-like properties prediction of a natural compound from the ethanolic extract of Cayratia trifolia (L.).

Background: Natural products have continually played an important role in drug discovery because it serves as active principles in drugs as well as templates for synthesis of new drugs. Cayratia trifolia (L.) is a medicinal plant, which has been reported to have antiviral, antibacterial, antiprotozoal, hypoglycemic, anticancer and diuretic activities.

Evaluation of in vitro enzymatic and non-enzymatic antioxidant properites of leaf extract from Alpinia Purpurata (Vieill.) K. Schum.

Objective: To evaluate the enzymatic and non-enzymatic antioxidants of leaf extract from Alpinia purpurata.

Methods: One gram of fresh leaf of Alpinia purpurata was grinded in 2 mL of 50% ethanol and centrifuged at 10,000×g at 4°C for 10 min. The supernatant obtained was used within 4 h for various enzymatic antioxidants assays like superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione S-transferase (GST), ascorbate oxidase, peroxidase, polyphenol oxidase (PPO) and non-enzymatic antioxidants such as vitamin C, total reduced glutathione (TRG) and lipid peroxidation (LPO).

Leaf extract of Alpinia purpurata (Vieill.) K. Schum screened for its phytochemical constituents and antibacterial and anticancer activities.

Objective: The study was formulated with the objective to assess phytochemical constituents, antibacterial activity and anticancer activity of Alpinia purpurata.

Methods: The leaves of A. purpurata were washed thoroughly by tap water, shade dried and powdered.
