Determination of Total Polyphenols from Fruit in Guizhou and Investigation Its Drying Methods
to study on the quality of Rose roxburghii fruit with different sources and different drying methods. Method: UV was used to determine the content of total polyphenols in 26 batches of samples with gallic acid as index component
single factor tests were adopted to optimize detecting conditions.Three kinds of drying ways were evaluated
cluster analysis was used to process and analyze the data. Result: Gallic acid had good linearity in the range of 2.5-5.4 mg·L-1 (r=0.999 7)
the average recovery rate was 102.93% with RSD of 3.3%.The average value of total polyphenols content in 26 batches of samples was 10.06%
22 batches of samples
which collected by us
had the average value of total polyphenols content at 10.77%; the rest 4 batches samples
which brought from market
had the average value of total polyphenols content at 6.14%.Compared with raw products
total polyphenols content in samples under oven drying at 60℃
decompression drying at 40℃ and freeze drying decreased by 33.57%
24.38% and 23.96%
respectively. Conclusion: This determination is simple and reprocucible.Drying ways have different effect on total polyphenols content in R. roxburghii fruit
decompression drying at 40℃ and freeze drying have small effect on the loss of total polyphenols.
