Bio-oil, with high oxygen-containing character, which was prepared from flash pyrolysis of rice stalk powders, was upgraded by the method of catalytic esterification with methanol. The esterified oil was distilled stepwise from 60 °C to 105 °C, and the fractions were analyzed with Fourier transform infrared spectroscopy (FTIR) and gas chromatography/mass spectroscopy (GC/MS) for the distribution of species. It was found that 58% of the components were detected in the fraction of 60 °C-80 °C, with 1,1-dimethoxypropan-2-one was the most abundant species. The residue, in which the boiling point of species were higher than 105 °C were resolved in acetone, and also analyzed with GC/MS. The results showed that phenols are the most abundant species, and following the ketones and hydrocarbons.

The present study was aimed to investigate the biologically active compounds present in the seed and leaf extracts of Millettia peguensis. Screening was done through preliminary qualitative analysis of phytochemicals and Gas Chromatography-Mass Spectroscopy (GC-MS) method. The study revealed the presence of alkaloids, carbohydrates, flavonoids, glycosides, gum and mucilage, phenolics, quinones, steroids and terpenoids in both aqueous and ethanol extracts of leaves and seeds. The GC-MS analysis of ethanol extracts of seeds and leaves have yielded 29 and 23 phytoconstituents, respectively. These observations were further validated by Fourier transform infrared spectroscopy (FT-IR) of the leaves and seeds powder. FT-IR has provided detailed information of the various functional groups associated with the compounds present in the samples. A single compound was isolated through Column Chromatography and Thin Layer Chromatography whose characterization was done through mass spectroscopy and IR spectroscopy.
