Bioassay-guided isolation studies on the extracts of yellow flowers of Tagetes patula L. against the Heterodera zeae were carried out to identify phytochemicals lethal to this economically important cyst nematode. In vitro investigation of a polar extract and fractions showing activity led to the isolation of phenolic compounds (flavonoids and phenolic(More)
CONTEXT Tagetes patula Linn. (Asteraceae) (French Marigold) flowers are used by local practitioners for cancer treatment; however, it lacks scientific justification. OBJECTIVE Identification of bioactive compounds in T. patula flower for cytotoxic and growth inhibition in human cancer cell lines along with its antioxidant properties using chemical and(More)
CONTEXT Tagetes patula L. is one of the French marigold group of the Asteraceae family. It is recognized in folklore for its medicinal and pesticidal properties. OBJECTIVE In search of more effective, but non-toxic compounds with antioxidative potential led to the bioassay guided isolation studies on the extracts of T. patula. MATERIALS AND METHODS The(More)
Automatic Number Plate Recognition (ANPR) can be identified as a technology which has been developed mainly based on Image Processing methodologies. It is being widely used in identifying vehicles in applications such as red-light enforcement, over speeding, bus lane control, motorway road tolling, border control and access/parking control. However axioms(More)
Rheumatoid arthritis (RA) poses a serious health problem as a chronic autoimmune joint disease with significant mortality and morbidity. Proinflammatory cytokines TNF-α and IL-1β, reactive oxygen species (ROS), and activated CD4(+) T-cells play key roles in the progression of arthritis. The aim of the study is to evaluate the in vitro and in vivo(More)
Patuletin isolated from Tagetespatula was used as a capping and reducing agent to synthesize in one pot gold nanoparticles capped with patuletin. Conjugation of gold with patuletin was confirmed by FT-IR and UV-visible spectroscopy and amount of patuletin conjugated to gold nanoparticles was found to be 63.2% by weight. Particle sizes were measured by(More)
ETHANOPHARMACOLOGICAL RELEVANCE Opuntia dillenii Haw (Nagphana) traditionally used against inflammation. The present study addressed the anti-inflammatory activity of O. dillenii derived methanol extract, fractions and pure compounds and their underlying mechanism of action. MATERIALS AND METHODS O. dillenii cladode methanol extract was subjected to(More)
