Isolation and Characterization of Alkaloidsfrom Ancistrocladus Heyneanus Leaves: A Phytochemical Study
Abstract: Leaves of Ancistrocladus heyneanus were collected from the forest of the Matheran hills of Maharashtra. From these leaves, alkaloids were extracted using dichloromethane, and two new monomeric Naphthyl-iso-quinoline alkaloids, Youndamine A and Ancistrocline were isolated using TLC and HPLC. HPLC/MS and NMR further identified the patient. The present study involves the collection and chemical investigation of the leaves of Ancistrocladus heyneanus, a plant species found in the forested regions of …

Bioalcohol Production: A Detailed Review
Abstract: Bioethanol stands as a pivotal player in the realm of renewable energy, deriving from organic materials abundant in sugars or their precursors. Its economic viability hinges largely on the affordability of substrates, which directly influences the overall cost of production. Microbial fermentation of carbohydrates, encompassing both pentose and hexose sugars, yields alcohols alongside valuable by-products, rendering bioethanol a versatile resource, particularly in the context of fuel production. The optimization of …

Significance of the Malondialdehyde (MDA) Bioassay Methods in Lipid Peroxidation
Abstract: Along with all the metabolic reactions, the cell cytoplasm is engaged in the process of production of the free radicals and reactive oxygen species (ROS). The overproduction of reactive oxygen species in cell cytoplasm leads into the condition of the oxidative stress. This situation may also be the results of the combination of excessive formation of radicals derived from oxygen or nitrogen or both. Cellular components may be attacked in …

Commercial Scale Quantification of Lignin
Abstract: Lignin, an aromatic biopolymer, in the terrestrial lignocellulosic biomass constitutes the single largest and sustainable source of biofuels and biochemicals. The recalcitrant nature of lignin is a hindrance to its chemical or biochemical conversion. Moreover, its insolubility in water too is a major challenge in its quantification which is a necessary step prior to and after its conversion. Though there are celebrated quantification methods like the classical Klason lignin method …

A Simplified High-Performance Liquid Chromatographic Method For Determination of Vitamin D3 in Human Serum
Abstract: Diabetes is a metabolic disorder caused by defective insulin secretion, insulin action or both. The two major factors for the development of diabetes are pancreatic beta cell dysfunction and insulin resistance. In type 2 diabetes mellitus, production and release of insulin is unobstructed but due to factors like ageing or obesity, the produced insulin cannot compensate for the increased demand. Measurement of the serum level of 25-hydroxyvitamin D3 is the …
