The parasitic angiosperm Cuscuta reflexa has a highly unusual carotenoid composition in that it does not contain neoxanthin, an otherwise ubiquitous component of the major light-harvesting complex protein (LHCIIb) in all other higher plant species studied to date. Combined HPLC and mass spectrometric analysis has enabled us to detect in tissues of C. reflexa two new types of xanthophylls: lutei...

This study demonstrates 5α-reductase inhibitory activity of certain herbs useful in the management of androgenic disorders. Ganoderma lucidum (Curtis) P. Karst (GL), Urtica dioica Linn. (UD), Caesalpinia bonducella Fleming. (CB), Tribulus terrestris Linn. (TT), Pedalium murex Linn. (PM), Sphaeranthus indicus Linn. (SI), Cuscuta reflexa Roxb. (CR), Citrullus colocynthis Schrad. (CC), Benincasa h...

A new phenolic compound, named 3-geranyl-2,5-dihydroxy-benzaldehyde (1), together with seven known chalone derivatives (2–8) has been isolated from the seeds of Celosia cristata L. Their chemical structures have been elucidated by spectroscopic analysis. All these compounds (1–8) were isolated from C. cristata for the

Inspired by the multicopper active site of laccase, which efficiently catalyzes the oxygen reduction reaction (ORR), herein we report a novel bio-inspired ORR catalyst composed of a multinuclear copper complex that was immobilized on the surface of reduced graphene oxide (rGO) via the covalently grafted triazole-dipyridine (TADPy) dinucleating ligand. This rGO-TADPyCu catalyst exhibited high OR...

In the present study, Polycarpaea corymbosa whole plant was extracted with ethanol and evaluated for anti-inflammatory activity in rats using a carrageenan induced paw edema. Ethanol extract exhibits potent anti-inflammatory activity at 500mg/kg at 3hr after administration. The study was compared with standard drug indomethacin (10mg/kg). Observed pharmacological activity in the present study p...
