There plant species of medicinal and vegatational fire break importance such as Berberis tinctoria, Elaegnus kologa and Rhodomyrtus tomentosa were identified in Nilgiri Biosphere Reserve and their eco-physiological behaviors were analysed. The study revealed that generally all the there species were having shorter period of seed dormacy, poor viability of seeds and higher mortality of saplings....

UNLABELLED In this research, the effects of low-density polyethylene (LDPE) packages containing micrometer-sized silver particles (LDPE-Ag) on microbial and sensory factors of dried barberry were investigated in comparison with the pure LDPE packages. LDPE-Ag packages with 1% and 2% concentrations of silver particles statistically caused a decrease in the microbial growth of barberry, especiall...

The stems of Berberis aristata DC. (Berberidaceae) are used in the South Asian traditional medicine as a key ingredient in formulations for eye care, skin diseases, jaundice, rheumatism and also in diabetes. B. lycium Royle and B. asiatica Roxb. are traded as equivalents of B. aristata. Conventional macro-morphology and microscopic examination does not aid in critically distinguishing the three...

A rapid, easy, and simple spectrophotometric method was developed for the estimation of total alkaloids precipitated by Dragendorff's reagent (DR) in plant materials. It is based on the formation of yellow bismuth complex in nitric acid medium with thiourea. The yellow-colored complex formed obeys Lambert-Beer's law in the concentration range of 0.06-50 microg/mL with lambdamax at 435 nm. Using...

A bioassay-guided fractionation and chemical investigation of the trunk of Berberis koreana resulted in the isolation and characterization of two new triterpenoids, 23-trans-p-coumaroyloxy-2alpha,3alpha-dihydroxyolean-12-en-28-oic acid (1), and 23-cis-p-coumaroyloxy-2alpha,3alpha-dihydroxyolean-12-en-28-oic acid (2), along with seven known triterpenoids (3-9). The structures of the new compound...
