Evaluation of in vitro enzymatic and non-enzymatic antioxidant properites of leaf extract from Alpinia Purpurata (Vieill.) K. Schum.
摘要
To evaluate the enzymatic and non-enzymatic antioxidants of leaf extract from Alpinia purpurata. One gram of fresh leaf of Alpinia purpurata was grinded in 2 mL of 50% ethanol and centrifuged at 10
000×g at 4°C for 10 min. The supernatant obtained was used within 4 h for various enzymatic antioxidants assays like superoxide dismutase (SOD)
catalase (CAT)
glutathione peroxidase (GPx)
glutathione S-transferase (GST)
ascorbate oxidase
peroxidase
polyphenol oxidase (PPO) and non-enzymatic antioxidants such as vitamin C
total reduced glutathione (TRG) and lipid peroxidation (LPO). The leaf extract of Alpinia purpurata possess antioxidants like vitamin C 472.92±6.80 μg/mg protein
GST 372.11±5.70 μmol of 1-chloro 2
4 dinitrobenzene (CDNB)-reduced glutathione (GSH) conjugate formed/min/mg protein
GPx 281.69±6.43 μg of glutathione oxidized/min/mg protein
peroxidases 173.12±9.40 μmol/g tissue
TRG 75.27±3.55 μg/mg protein
SOD 58.03±2.11 U/mg protein
CAT 46.70±2.35 μmol of H2O2 consumed/min/mg protein in high amount whereas ascorbate oxidase 17.41±2.46 U/g tissue
LPO 2.71±0.14 nmol/L of malondialdehyde formed/min/mg protein and PPO 1.14±0.11 μmol/g tissue in moderate amount. Alpinia purpurata has the potential to scavenge the free radicals and protect against oxidative stress causing diseases. In future
Alpinia purpurata may serve as a good pharmacotherapeutic agent.
