摘要

Antioxidant activities of aqueous ethanol extracts of five wild vegetables (Penthorum chinense Pursh, Gynura divoricala, Gynura bicolo (Roxb.) DC, Talinum paniculatum (Jacq.) Gaertn, and callipteris esculenta(Retz)J.Sm) were determined using antioxidant activity, reducing capacity and DPPH radical scavenging activity methods. Extracts of Penthorum chinense Pursh were strong in the DPPH radical scavenging activity and reducing capacity, and extract of Gynura divoricala (L.) D.C has good antioxidant activity. The antioxidant capacity of ethnol extract from five wild vegetables were different in ethnol extract, had a liner relationship with the phenolics content. Satisfying test results were obtained, which lead to considering the use of these vegetables as health-promoting ingredients.Introduction Wild vegetables often have better antioxidation, the ordinary wild eaten vegetables in hainan like five wild {Penthorum chinense Pursh, Gynura divoricala D.C, Gynura bicolo (Roxb.) DC, Talinum paniculatum (Jacq.)Gaertn, and callipteris esculenta (Retz) J.Sni) were chosen to determine antioxidant activity (AC), reducing capacity (RP) and DPPH radical scavenging activity, by exploring the relavance between the antioxidant capacity and phenolics content to give a basic theory of the study and application of the functional food and new pharmaceutical material. Furthermore, the UV-VIS spectrum of several extracts would contribute to further knowledge relating to the screening of antioxidant compounds into these plant materials.
