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.

Sugarcane peel is an agrowaste product and contains considerable amount of wax. This has a good technoeconomic potential. In view of this, the present study aims at extraction and characterization of wax from sugarcane peel. The yield of crude wax was 0.95% on dry weight basis. During Fourier transform-infrared spectroscopy (FT-IR) prominent peaks obtained at 2921.73 and 2851.64 (–CH), 1463.44 (–CH2), 1376.96 (–CH3), 1108.4 and 1170.16 (–C–O) 3395.60 (–OH), 1710.25 (–CHO), and 1736.63 (–COOH) indicate presence of alkanes, ketones, alcohols, aldehydes, and carboxylic acids, respectively. Alcohol and hydrocarbon fractions were also found by thin layer chromatography (TLC). Melting point of crude wax was observed to be 62.1°C. Molecular weight of wax was estimated to be 1706 Dalton. Composition of crude wax found using gas chromatography-mass spectroscopy (GC-MS) was alkanes (28.83%), ester (66.26%), fatty acids (4.58%), aldehyde (0.11%), and alcohol (0.22%).

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.

Endogenous Steroids

The 5,7-dienes, 3β-hydroxy-5,7-pregnadien-20-one and 3β-hydroxy-5,7-androstadien-17-one were extracted from fetal horse gonads and purified by solvent partition, thin-layer chromatography and high performance liquid chromatography. The isolated steroids were identified by comparison with the synthetic steroids using ultraviolet and mass spectroscopy and by gas chromatography–mass spectroscopy. The identification of these compounds as endogenous steroids, together with the data on their biosynthesis reported previously, support the proposal that in the fetal horse gonad there is a 5,7-diene pathway biosynthesizing 3β-hydroxy-5,7-androstadien-17-one, which is the proposed precursor for equilin in the placenta.
