Background The Biarum species (Kardeh) has been consumed as a traditional functional food and medicine for decades. The current study investigates the phytochemistry, in-vitro and in-vivo bioactivities of methanol extracts of B. bovei. Methods The Gas-chromatography mass spectrophotometer (GS/GS-MS) was used to analyze the phytochemical profile of the methanol extracts of B. bovei leaves and corms. The B. bovei extracts (BBE) were also investigated for in-vitro antioxidant, anticancer, and in-vivo acute toxicity (2000 mg/kg) activities. Results The chemical profiling of BBE revealed mainly fatty acids, phytosterol, alcohols, and hydrocarbon compounds. Namely, Linoleic acid, eliadic acid, palmitic acid, 22,23-dihydro-stigmasterol, and campesterol. The antioxidant activity of BBE ranged between 0.24-3.85 μg TE/mL based on different assays. The extracts also exhibited significant anticancer activity against DU-145 (prostate cancer cells), MCF-7 (human breast adenocarcinoma), and HeLa (human cervical cancer) cell lines with IC 50 values ranging between 22.73-44.24 μg/mL. Rats fed on 2000 mg/kg dosage of BBE showed absence of any toxicological sign or serum biochemical changes. Conclusion The detected phytochemicals and bioactivities of BBE scientifically backup the folkloric usage as an important source of nutraceuticals and alternative medicine for oxidative stress-related diseases and carcinogenesis inhibition.

In this study, antioxidative activities of aqueous extract of Biarum bovei (BBE) in stabilizing of canola oil during storage at 20°C was evaluated. For this purpose, the total phenolic (TP), flavonoids (TFC), and tocopherol content (TTC) of the extract were determined and β-carotene bleaching system was used to assess the antioxidant efficacy of BBE. The amount of TP, TFC, and TTC in BBE indicated high antioxidant activity. So, different concentrations (0, 200, 800, and 1400 ppm) of BBE and butylatedhydroxyanisole (BHA; 100 ppm), were added to canola oil for 60 days at 20°C. Peroxide value (PV), carbonyl value (CV), Total polar compounds (TPC), acid value (AV), iodine values (IV), and conjugated dienes (CD) were employed to evaluate the BBE effect on canola oil stabilizing. Results indicated that 1,400 ppm of BBE exhibited stronger antioxidant activity in canola oil than BHA.
