Abstract

The aim of this study was to determine Total Phenolic Compound (TPC) and antioxidant activity changes depending on the ripening in Rosa canina, R. dumalis, R. dumalis ssp. boissieri and R. villosa rosehip species. Rosehip fruits were harvested in 6 different times from July to September. TPC content and antioxidant activities were determined by spectrophotometric methods. TPC and antioxidant activities of the studied species increased during ripening. TPC (1510.57 mg GAE 100 g/H-6) and antioxidant activities (TEAC: 364.12 μmol trolox equivalent g/H-6 and FRAP: 286.79 μmol trolox equivalent g/H-6) were higher in R. dumalis (MR-15) than the other studied species. There was a high correlation between the TPC and the antioxidant activity. Also, there was a positive correlation between maturation, phenolics and antioxidant activities. This correlation was high in R. dumalis and low in R. canina. However, it was not possible to express the existence of a relationship between temperature, TPC, and antioxidant activity. It was possible to express the existence of correlations between the color of fruits and some studied characteristics. The correlations between the colors of the fruits and TPC and antioxidant activity of R. dumalis were found higher than the other species.

玫瑰果成熟过程中总酚类化合物及抗氧化活性的变化

本研究的目的是测定狗蔷薇、杜马花、杜马花三种植物总酚类化合物(TPC)及其抗氧化活性随成熟期的变化。蔷薇属和紫蔷薇属。从7月到9月，在6个不同的时间收获玫瑰果。分光光度法测定TPC含量及抗氧化活性。TPC和抗氧化活性随着成熟而增加。杜马草(mr15)的TPC (1510.57 mg GAE 100 g/H-6)和抗氧化活性(TEAC: 364.12 μmol trolox当量g/H-6和FRAP: 286.79 μmol trolox当量g/H-6)均高于其他研究种。TPC与抗氧化活性之间存在较高的相关性。成熟度、酚类物质与抗氧化活性呈正相关。这种相关性在杜马鼠中较高，在犬鼠中较低。然而，不可能表达温度、TPC和抗氧化活性之间存在关系。有可能表示水果的颜色与所研究的某些特征之间存在相关性。果实颜色与TPC及抗氧化活性的相关性高于其他树种。
