Phytochemical screening of Bixa orellana and preliminary antidiabetic, antibacterial, antifibrinolytic, anthelmintic, antioxidant, and cytotoxic activity against lung cancer (A549) cell lines

Abstract

Bixa orellana (B. Orellana) is a frequently utilized plant that has grown in significance in pharmaceutical applications. The leaves extract of B. orellana was used in the current study for preliminary phytochemical analysis in terms of both quantitative and qualitative, which indicates the presence of phenols, alkaloids, and flavonoids. Furthermore, the extract demonstrated antifungal activity at 30 mm zone of clearance against Candida albicans and antibacterial activity at 16 mm zone of clearance against Bacillus nakamuria by well diffusion method against different strains. The plant extract showed a MIC of 20 µg/mL and MBC of 157.11 µg/mL against E. coli by ELISA and broth dilution method, respectively. To evaluate the phytochemicals in the extract, further purification of the extract by TLC, column chromatography, and component analysis by GC–MS, which reported 18 components, and UV spectrum were performed. A number of therapeutic applications for the extract were observed, including antidiabetic activity (anti-glucosidase) of 98.34% inhibition at 100 µg/mL, anti-lipase of 100% inhibition at 100 µg/mL, and anti-amylase activity of 100% inhibition at 100 µg/mL, antioxidant activity (anti-DPPH activity) of 59.74% inhibition at 100 µg/mL, anthelmintic at 1 min by 1000 µg/mL, antifibrinolytic at 20 secs by 1000 µg/mL and cytotoxic activity against A549 lung cell lines, wherein, the cell viability was below 40 % at the highest dose (100 µg/mL), with an IC50 value of 39.9 µg/mL.
