Smilax china (SC) is a medicinal plant that has been traditionally used for a number of pathological disorders. In current study, its various fractions were assessed for radical scavenging, phenolic, flavonoid content and enzyme inhibition. The methanolic extract (MSC) of SC was subjected to fractionation using different solvents including n-hexane, benzene, chloroform, ethyl acetate and n-butanol. Results revealed that ethyl acetate fraction showed maximum phenolic (101.81 ± 0.13 mg GAE/g) and

Whereas, maximum α-Glucosidase (87.56 ± 0.13%) and Acetylcholinesterase (AChE) inhibition (82.34 ± 0.64%) was exhibited by n-hexane and benzene fractions, respectively. Present study has revealed the promising radical scavenging, phenolic, flavonoid and enzyme inhibitory potential of various fractions of SC extract. Thus, the study is a step forward towards evidence-based phyto-medicine.
