Abstract Background Herbal plants are potent in curing various ailments of ancient times as they have comparatively lesser side effects. The demands for natural drugs, mostly from plant sources, are increasing over the past few decades. Because of their potent antioxidant activity, Acacia species are used to treat a variety of diseases. One of the species Acacia ferruginea, an endangered medicinal plant, is widely used in the traditional medicine system, and it is considered that standardization would be beneficial. The present study investigates the physicochemical parameters, preliminary phytochemical screening, trace metals by SEM–EDS, and fluorescence properties of various extracts (non-polar to polar) of leaf and bark parts. Standard spectrophotometric methods (UV–Vis, FT-IR, fluorescence spectroscopy) are employed to analyze the functional groups, and the DPPH and total antioxidant methods are used to assess antioxidant potential. Results The ethyl acetate extract of leaves and ethanol extract of the bark are found to be the highest in yield, 16.32% and 2.54%. Results reveal that the total ash percentage and moisture content are of bark and the water-soluble ash of leaves is higher (10.3 ± 0.85, 7.6 ± 0.34, 3.22 ± 0.24%). The bark polar extract contained more macro-elements such as Na, K, Mg, Ca, S, and Cl. Phytochemical analysis reveals the polar extracts of leaves and bark show saponins, flavonoids, steroids, phenolic compounds, and non-polar extracts show mild positive. The total alkaloids, phenolics, and terpenoids (1.58 ± 0.08%; 0.56 ± 0.11; 0.75 ± 0.15) are found to be higher in A. ferruginea leaves. The FT-IR result shows the presence of alkanes, alkenes, aromatic compounds, aldehydes, phenolics and does not contain any toxic substances since there is no peak observed in the region between 2220 and 2260 cm−1. The in vitro antioxidant activity of the species demonstrated that both the leaf and bark parts have prominent antioxidant properties. Conclusions The results obtained from the preliminary standardization of A. ferruginea are very helpful in the determination of the quality and purity of the crude drug. The refurbished findings of A. ferruginea are promising, and further research is important to identify the bioactive compounds, thereby developing nutritional supplements and medications through therapeutic compound isolation.

Abstract. The stability of B12 vitamers is affected by interaction with other water-soluble vitamins, UV light, heat, and pH. This study compared the degradation losses in cyanocobalamin, hydroxocobalamin and methylcobalamin due to the physicochemical exposure before and after the addition of sorbitol. The degradation losses of cyanocobalamin in the presence of increasing concentrations of thiamin and niacin ranged between 6%-13% and added sorbitol significantly prevented the loss of cyanocobalamin (p<0.05). Hydroxocobalamin and methylcobalamin exhibited degradation losses ranging from 24%–26% and 48%–76%, respectively; added sorbitol significantly minimised the loss to 10% and 20%, respectively (p < 0.05). Methylcobalamin was the most susceptible to degradation when co-existing with ascorbic acid, followed by hydroxocobalamin and cyanocobalamin. The presence of ascorbic acid caused the greatest degradation loss in methylcobalamin (70%-76%), which was minimised to 16% with added sorbitol (p < 0.05). Heat exposure (100 °C, 60 minutes) caused a greater loss of cyanocobalamin (38%) than UV exposure (4%). However, degradation losses in hydroxocobalamin and methylcobalamin due to UV and heat exposures were comparable (>30%). At pH 3, methylcobalamin was the most unstable showing 79% degradation loss, which was down to 12% after sorbitol was added (p < 0.05). The losses of cyanocobalamin at pH 3 and pH 9 (~15%) were prevented by adding sorbitol. Addition of sorbitol to hydroxocobalamin at pH 3 and pH 9 reduced the loss by only 6%. The results showed that cyanocobalamin was the most stable, followed by hydroxocobalamin and methylcobalamin. Added sorbitol was sufficient to significantly enhance the stability of cobalamins against degradative agents and conditions.
