Physicochemical characterization, bioactive compounds, in vitro antioxidant activity, sensory profile and consumer acceptability of fermented alcoholic beverage obtained from Caatinga passion fruit (Passiflora cincinnata Mast.)

The bioactive compounds, as well as the in vitro antioxidant activity of two Savoy cabbage cultivars, Dama and Leticia, grown in west of Spain under similar conditions were identified, quantified and compared. We found that cv. Dama presented in general betters results when compared with cv. Leticia. Cv. Dama presented higher concentrations of chlorophyll a (2.26 mg/100 g fresh weight), total phenolic content (102.71 mg of chlorogenic acid equivalent/100 g fresh weight) and total intact glucosinolates (195.22 µmol of sinigrin equivalent/100 g fresh weight). Thus, cv. Dama exhibited higher values of in vitro antioxidant activity.

“Anantmul” is an important and widely used medicinal plant. The study aimed to determine the physicochemical composition, bioactive compounds and antioxidant activity of Hemidesmus indicus (Asclepiadaceae). The roots of the plant were collected and sequentially extracted using petroleum ether, ethyl acetate, and methanol. The preliminary phytochemical screening of extracts was carried out and found to be a good source of bioactive compounds. Biological activities of flavonoid and phenolic compounds have been discovered in several latest studies. Further phytochemical isolation was carried out, and Lupeol was isolated. Phenols are shown to be multifunctional antioxidants which will perform as singlet oxygen quenchers. Lupeol was evaluated for in-vitro antioxidant activity. It showed a correlation with antioxidant activity by DPPH (IC50 = 0.52, P 6 0.05) and H2O2 (IC50 = 0.43, P 6 0.05). The results show promising perspectives for the exploitation and use of anantmul rhizome as a constituent of anti-aging as well as anticancer diet. Keywords: Anantmul, Lupeol, Antioxidant, DPPH

In Vitro Antioxidant Activity

Plants are known to contain phytochemicals of pharmacological relevance and as such have been utilized in the treatment and management of various diseases. Morinda lucida, a medium size tropical tree belonging to the rubiaceae family and widely distributed in Africa is one of these plants. It has been reportedly used in the traditional treatment and management of diseases. This study is aimed at identifying compounds with pharmacological relevance in the ethanol extract of Morinda lucida leaves, the antioxidant activity and lethal dose determination of the extract. The leaves of Morinda lucida was extracted with ethanol; phytochemical and bioactive compounds analysis, in vitro antioxidant activity and lethal dose (LD50) determinations were carried out. It was observed in the study that the extract contains alkaloids, quinines, quinones, flavonoids and tannins. The gas chromatography mass spectrometry (GC-MS) identified phenol 2, 4-bis (1,1-dimethylethyl) (2.82%), Stilbenes (12.32%), Phenoxazine (2.60%) and Benz(cd) indol-2(1H)-one, 1-methyl- (2.60%) amongst other compounds in the extract. The in vitro antioxidant activity evaluation of the extract revealed that it possesses a significant antioxidant activity which increased with increasing concentration. The LD50 determination revealed the extract was safe as there was no death recorded even at a dose as high as 5000 mg/kg. This study shows that Morinda lucida possesses enormous pharmacological potentials.
