The present study describes the optimization of a simple and reliable method for the determination of four first line antitubercular drugs in human plasma. The studied analytes were isoniazid (H), rifampicin (R), pyrazinamide (Z) and ethambutol (E) in fixed dose combination recommended to patients under the Revised National Tuberculosis Control Programme (RNTCP, India). The analytes were extracted from the human plasma (150 μL) using the single step liquid-liquid extraction approach and were analyzed by liquid chromatography (LC) coupled to tandem mass spectrometry (MS/MS).

A rapid and sensitive method for the extraction and determination of four major polyphenolic components in Euphoria longana Lam. seeds is presented for the first time based on matrix solid-phase dispersion extraction followed by ultra high performance liquid chromatography with hybrid triple quadrupole linear ion trap mass spectrometry. Matrix solid-phase dispersion method was designed for the extraction of Euphoria longana seed constituents and compared with microwave-assisted extraction and ultrasonic-assisted extraction methods.

Objective: To isolate and characterize the alcohol-producing yeasts from Woodfordia fruticosa flowers, which are used for the induction and maintenance of fermentation in the making of Ayurvedic formulations.

Materials And Methods: Initially twenty four yeasts strains were isolated on MGYP agar plate. Among them, four strains were selected for further studies on the basis of their alcohol generation capacity using jaggery media (50% w/v).
