Objective: To prepare olive chewable tablets and investigate its antioxidant capacity. Method: With flavor

appearance

taste and hardness as composite index

orthogonal test was adopted to optimized formulation technology of olive chewable tablets by taking dosage of lactose

magnesium stearate

mannitol and PVP-k30 as factors.The content of polyphenols from olive chewable tablets was determined by HPLC

chromatographic conditions were:C18 column(4.6 mm×250 mm

5 μm)

mobile phase of acetonitrile-0.085% phosphoric acid(8:92)

detection wavelength 280 nm

flow rate 1 mL·min-1.Antioxidant capacity of olive chewable tablets was evaluated by investigating its scavenging DPPH free radicals. Result: Optimal formulation technology was as following:33% raw material medicine

10% lactose

35% mannitol

10% PVP-K30

1% magnesium stearate

each tablet (0.38 g) containing gallic acid of 1.64 mg

ability of olive chewable tablets to scavenging DDPH free radicals was better than Vitamin C. Conclusion: These prepared olive chewable tablets had antioxidant health function with good taste

it could provide some certain ideas on protection and development of geoherbs in the South China.
