Introduction. Sorghum is available cereal seeds of African origin belonging to the Poaceae family. However, its metabolites and proximate composition have not studied well, which led to the under-utilization of this cereal. This research aimed to investigate the classes of phytochemical and proximate compositions of sorghum extract in order to assess its nutraceutical potential for food chemistry and dietary formulations. Study objects and methods. We studied the sorghum seed oil extract obtained with the help of a Soxhlet extractor. Sorghum was purchased in Ota, Nigeria. The bioactive compounds were identified by standard methods of phytochemical screening, the nutritional content was investigated with proximate analysis, and the secondary metabolites in the sorghum extract were determined using gas chromatography – mass spectrometry (GC-MS). Result and discussion. The phytochemical screening showed the presence of steroids, saponins, terpenoids, alkaloids, cardiac glycosides, and quinones in the sorghum extract. The oil yield obtained was 11.00 ± 0.18%. The proximate analysis revealed 5.94% moisture content, 3.05% ash, 0.20% crude fiber, 11.00% fat, 5.54% protein, and 74.27% carbohydrates. The selected physicochemical parameters measured in the sorghum extract included cloud point (0.40°C), specific gravity at 25°C (0.81), and refractive index (1.46). The GC-MS analysis revealed the presence of 9,12-octadecadienoic acid (Z,Z)-, stigmasterol, 8-dodecen-1-ol, acetate, (Z)-, vitamin E, linoleic acid ethyl ester, and 9,12-octadecadienoic acid, methyl ester, which accounted for about 85% in the sorghum composition. Other constituents, presented at lower amounts, included 12-heptadecyn-1-ol, 1H-Imidazole-5-ethanamine, 1-methyl-, and cyclononene. Conclusion. The findings of this study revealed high nutritive potential of sorghum, which make it a rich source of energy for humans and animals.

Background: Polyherbal plant extracts which usually comprise of two or more plant parts often contain a wide array of key phytoactive constituents relevant in attaining greater therapeutic efficacy. The active constituents derived from individual plants are insufficient to provide attractive pharmacological action when compared to a combination of multiple herbs. Objective: To conduct phytochemical screening of polyherbal aqueous leaf extracts                            (PALE) and analysis of compounds present in it by gas chromatography-mass spectrometry (GC-MS). Materials and Methods: The polyherbal extract was prepared from the combined aqueous extracts of leaves of Alchornea cordifolia, Sorghum bicolor and Pennisetum glaucum using ratio 1:1:1 w/v. Phytochemical screening was done via standard analytical methods. The identification and characterization of compounds by GC-MS analysis was performed on gas chromatography system coupled with mass spectrometry. Results: The phytochemical analysis of PALE revealed the presence of phenols, saponins, flavonoids, alkaloids and tannins in varying quantities. GC-MS analysis of the extract depicts the presence of key bioactive compounds. Thirty-two bioactive compounds were identified with various retention time and % peaks. The major compounds identified in terms of % peak area are n-Hexadecanoic acid (6.72), Hexadecanoic acid, ethyl ester (7.28), 9,12-Octadecadienoic acid (16.54) and 9-Octadecenoic acid ethyl ester (12.92). Disulfide, dimethyl (0.04), 2-Methoxy-4-vinylphenol (0.28), 1-Dodecanol (0.85), 10-Phenyldecanoic acid (0.12), 1-Hexadecanol (0.75), Methoxyacetic acid, pentadecyl ester (0.27), 9-Octadecenoic acid (Z)-, phenylmethyl ester (0.16), Hexadecanoic acid, 2-hydroxy-1-(hydroxymethyl) (1.09), were among the minor compounds identified in the extract. From the study, 9,12-Octadecadienoic acid indicated the highest peak with a retention time of 20.556 minutes and % peak area of 16.54%. Conclusion: The presence of the revealed bioactive constituents in PALE may suggest its nutraceutical, pharmacological and therapeutic relevance. Therefore, in view of the medicinal importance associated with the observed bioactive constituents, further studies on the toxicity level of  the extract is advised subsequently.

This paper reports on the chemical compounds in arabica coffee beans with a high Specialty Coffee Association (SCA) cupping score, especially those in specialty coffee beans. We investigated the relationship between the chemical compounds and cupping scores by considering 16 types of Coffea arabica (arabica coffee) beans from Guatemala (SCA cupping score of 76.5–89.0 points). Non-targeted gas chromatography-mass spectrometry-based chemometric profiling indicated that specialty beans with a high cupping score contained considerable amounts of methyl-esterified compounds (MECs), including 3-methylbutanoic acid methyl ester (3-MBM), and other fatty acid methyl esters. The effect of MECs on flavor quality was verified by spiking the coffee brew with 3-MBM, which was the top-ranked component, as obtained through a regression model associated with cupping scores. Notably, 3-MBM was responsible for the fresh-fruity aroma and cleanness of the coffee brew. Although cleanness is a significant factor for specialty beans, the identification of compounds that contribute to cleanness has not been reported in previous research. The chemometric profiling approach coupled with spiking test validation will improve the identification and characterization of 3-MBM commonly found in arabica specialty beans. Therefore, 3-MBM, either alone or together with MECs, can be used as a marker in coffee production.

Danshen ( Salvia miltiorrhiza Bunge) is one of the most used medicinal plants in the Oriental medicine and has been well studied for application in modern medicine. In our continuing study on chemical constituents of danshen cultivated in Vietnam, using chromatography separation resulted in the isolation of six phenolic compounds including a benzophenone, iriflophenone 2- O- α-L-rhamnopyranoside (1), and five phenolic acids including rosmarinic acid (2), rosmarinic acid methyl ester (3), rosmarinic acid ethyl ester (4), salvianolic acid A methyl ester (5) and salvianolic acid A ethyl ester (6) from the butanol portion of the danshen crude extract. Beside the typically main phenolic acid components, to our knowledge, iriflophenone 2- O- α-L-rhamnopyranoside (1) was first isolated from salvia sp. On biological testing, compound 1 showed strong antiproliferative activity on HL-60 leukemia cells with the IC50 of 8.9 μM; compounds 1 and 3–6 inhibited markedly nitric oxide production in lipopolysaccharide-treated RAW 264.7 cells.
