เมื่อวัดค่าการดูดกลืนแสงที่ความเข้ม

When the absorption measurements at 1mg/ml concentration, it is not in the range of values of stainless steel deck light absorption. When adding a concentration 5 mg/ml soluble, so it can not be prevented, which may be measured, means all three extracts, this section does not have the quantity, total polyphenol.

When measuring the absorbance at a concentration of 1mg / ml, it is not within the range of the optical absorption of the Stan-dard. When the concentration of 5 mg / ml, it can not be dissolved. It can not be measured. This may refer to extract all three parts of this total polyphenol.

When measuring the absorbance at 1mg / ml it is out of the range of absorbance of Tan lining. When the concentration is 5 mg / ml it cannot dissolve, it can not measure. Which may refer to extract these three parts no volume total polyphenol.
