Determination of the Content of Phenolic Compounds and the Changes of Polyphenol Oxidase and Each Index during Browning of Phyllanthus emblica at Different Storage Temperatures

Table 3

Linear equation, R², and range of rutin for quantitative determination.

Compound	Regression equation	R^2	Range (µg)
Rutin	Y = 1513.8X − 9.24	0.9992	0.16–0.96

R² means coefficient of determination. The above data are all greater than 0 and less than 1, showing that the model fits well.
