This work reports the determination of the total contents of flavonoids and phenolic acids of two extracts of the bamboo shoots and on this basis, studied the free-radical scavenging function of the ethanol and hydro alcoholic extracts by the DPPH, total antioxidant capacity, Hydrogen peroxide, superoxide and Lipid peroxide method and anti-inflammatory activity by the protein denaturation and HRBC membrane stabilization method. The experimental results show that there are large amounts of flavonoids and phenolic acids in the bamboo shoots. Through the research of antioxidant and anti-inflammatory activity it shows that the extracts of the bamboo shoots have strong free-radical scavenging power. By doing the relevant analysis for the contents and antioxidant and antiinflammatory potential of the bamboo shoot extracts, we know that there is strong correlation between the contents of phenols and flavonoids in the bamboo shoots. It is concluded that the hydro alcoholic extract of bamboo shoot have strong antioxidant and anti-inflammatory activity, thus provide scientific data for their further development and exploitation.
