(Cycadaceae), is an endemic and critically endangered, tropical, dry deciduous, dioecious gymnosperm present in varied region of adjunct areas of Tirumala Hills, Seshachalam Biosphere Reserve, Southern Eastern Ghats, India. lessThan i greaterThan In vitro lessThan /i greaterThan antioxidant studies by employing different parameters such as DPPH, TAC, ABTS and superoxide radical scavenging activity have been tested with different extracts viz., methanolic, ethyl acetate and n-Hexane. Screening for biochemical availability was done for flavonoids and phenolics and were evaluated statistically which showed positive correlations among biochemical availability and antioxidant activities with all the extracts. This study suggests that all the extractives showed antioxidant potency and laid a scientific proof that lessThan i greaterThan C. beddomei lessThan /i greaterThan male cones are new potential source of natural antioxidants.
