Studies on Changes in Carbohydrate Metabolism in Regular Bearing and “Off” Season Bearing Cultivars of Mango (Mangifera indica L.) During Flowering

Abstract: Studies were conducted at Indian Institute of Horticultural Research, Bangalore, India, to compare the role of carbohydrate and its metabolizing enzymes in “off” season bearing cultivar Royal Special and regular bearing cultivar Totapuri during the time of flowering. Totapuri is a regular bearing cultivar mainly used for processing and has high yielding potential. “Off” seasonal cropping in mango is the unique feature of mango cultivar Royal Special which contributes to “off” season mango production under South Indian conditions. During the bud swelling stage, the maximum reducing sugars contents were recorded while higher chlorophyll a and b values were recorded during bud break stage in ‘Royal Special’ as compared to ‘Totapuri’. Higher acid invertase activity was recorded during emergence of panicles, and increased amylase activity was observed during pre-swelling stage in ‘Royal Special’. Sucrose and its metabolizing enzymatic activities increased during flowering, indicating their decisive role in the...

In vitro antioxidant activity of Holarrhena antidysenterica Wall. methanolic leaf extract.

Abstract: Antioxidative potential of methanolic leaf extract of Holarrhena antidysenterica was evaluated using hydroxyl radical, superoxide anion scavenging and reducing power assays. The antioxidant activity of the methanol extract increased in a concentration-dependent manner. The extract showed significant reactive oxygen species (ROS) scavenging activity in all in vitro antioxidant assays and contained high level of total phenolic content.

Catalytic performance study of nano-cobalt: a catalyst for complement to the Heck coupling reaction

Abstract: Easy and convenient synthesis of crystalline cobalt-nanoparticles by a seed mediated growth method with cetyltrimethylammonium bromide used as surfactant, KI as an additive and ascorbic acid as reductant; this synthesized Co-nanoparticle are characterized by XRD and TEM analysis, and is used as a coupling catalyst for alkenes with aryl halides in the presence of a base. The yield of the catalyzed product and the method has many advantages such as affordable and ligand-free condition. Hence overall reaction is augmented to the Heck coupling reaction.
