Caralluma edulis is a leafless succulent herb native to India and Pakistan,where it is used as emergency food and as potential herbal *** was investigated for its bioactive chemicals and further medicinal *** objective of the current study was to accomplish the chemical and biological characterization of *** profiling was done through estimation of total bioactive contents and UHPLMS *** screening was achieved through six different antioxidant and enzyme inhibition *** of its phenolic and flavonoid contents revealed that ethyl acetate fraction(Ce-E)contains 14.15 mg GAE/g extract and 26.13 mg RE/g extract of phenolics and flavonoids,respectively,followed by the methanolic(Ce-M)and the water(Ce-W)soluble *** free radical inhibitory assays,Ce-E fraction also exhibited highest activity(DPPH:19.72 mg TE/g extract,ABTS:48.66 mg TE/g extract)followed by Ce-M,whereas,in CUPRAC and FRAP assays,all the extracts,except water fraction,exhibited nearly equal potential in the range of 53.85–57.96 and 25.42–32.12 mg TE/g extract,*** metal chelating antioxidant assay,only Ce-M and Ce-W fractions displayed considerable activities(25.88 and 23.55 mg EDTAE/g extract respectively),whereas,Ce-H exhibited the highest activity in phosphomolybdenum assay(1.03 mmolTE/g extract),against BChE(6.43 mg GALAE/g extract),α-glucosidase andα-amylase(6.98 and 0.47 mmol ACAE/g,respectively)and tyrosinase(64.46 mg KAE/g extract)***-M and Ce-E also exhibited significant activity against tyrosinase(59.85 and 58.40 mg KAE/g extract,respectively).Crude methanolic extract(Ce-M)was analyzed to unveil its secondary metabolic picture;the uhplcms analysis discloses 105 compounds as phenolic acids,flavonoids,steroids and their glycosides,which makes the *** extract a strong candidate for nutraceutical and functional food *** of the metabolites were docked against all the tested enzymes to predict mode of
