Evaluation of the Antibacterial and Antioxidant Properties of Chemical Constituents of the Roots of : An Integrated Approach of Experimental and Computational Study.

is a medicinal plant used for the treatment of malaria, toothache, and stomach problems. The root parts of the plant are also used for healing liver disorders. Silica gel chromatography separation of CHCl/MeOH (1:1) and MeOH extracts of roots of result in the isolation of three compounds, namely, bergenin (), -sitosterol (), and epigallocatechin 3-gallate (), reported herein for the first time from the plant.

antibacterial and antioxidant activity of flavonoids from the roots of : a combined experimental and computational study.

is a traditional medicinal plant used to treat hypertension, diarrhea and urinary disorders. Silica gel chromatographic separation of CHCl/MeOH (1:1) roots extract of afforded seven compounds namely; β-sitosterol (), stigmasterol (), 6a, 12a-dehydro-deguelin (), tephrosin (), maackiain (), obovatin () and 6-oxo, 6a, 12a-dehydro-deguelin (). GC-MS analysis of essential oils from the root of displayed a total of 17 compounds of which cis-nerolidol (41.

Antibacterial and Antioxidant Efficacies of Secondary Metabolites from the Roots of : A Combined and Study.

is a therapeutic plant traditionally used to treat rabies, snake bite, diarrhea, and wound healing. To address the bioactive compounds exhibiting these activities, we performed a comprehensive study on the roots of the plant. Thus, the present study aims to inspect the antioxidant and antibacterial efficacies of compounds isolated from the combined dichloromethane : methanol (1 : 1) and methanol extracts of along with the study of their interaction with selected protein targets.

antimicrobial and antioxidant activities, essential oil composition, and molecular modeling analysis of secondary metabolites from roots of .

is locally used to treat wound, stomachache, viral infection, cancer, sunstroke fever, abdominal colic, diarrhea, hemorrhage, anthrax, and hepatitis. The objective of this study was to identify the compounds and to evaluate the antimicrobial and antioxidant activity of the extracts and isolated compounds from . The H-NMR, C-NMR, and DEPT-135 were used to elucidate the structures of isolated compounds.

Miscanthus Giganteus: A commercially viable sustainable source of cellulose nanocrystals.

With a goal of identifying a new scalable source for cellulose nanocrystals (CNCs), we successfully isolated CNCs from a sustainable, non-invasive grass, Miscanthus x. Giganteus (MxG). Subjecting MxG stalks to base hydrolysis, bleaching and acid hydrolysis allowed access to cellulose nanocrystals (MxG-CNC) in high yields.

Humicola insolens cutinase-catalyzed lactone ring-opening polymerizations: kinetic and mechanistic studies.

This paper explores reaction kinetics and mechanism for immobilized Humicola insolenscutinase (HIC), an important new biocatalyst that efficiently catalyzes non-natural polyester synthetic reactions. HIC, immobilized on Lewatit, was used as catalyst for epsilon-caprolactone (CL) and omega-pentadecalactone (PDL) ring-opening polymerizations (ROPs). Plots of percent CL conversion vs time were obtained in the temperature range from 50 to 90 degrees C.

Application of bis(diphenylphosphino)ethane (DPPE) in Staudinger-type N-glycopyranosyl amide synthesis.

Bis(diphenylphosphino)ethane (DPPE) reacts with pyranosyl azides derived from D-glucose and D-glucuronic acid in the presence of acid chlorides to yield the corresponding glycosyl amides. Reaction rates are comparable to those with triphenylphosphine, however, the byproduct phosphine oxide is easily removed from reaction mixtures using column chromatography. The simple and clean workup allows for the formation of collections of related compounds by parallel synthesis, and the method is also applicable to scaled-up reactions.
