Determination of Triterpenoid Content
2017-09-04
According to the linear regression equation of oleanolic acid, calculate the concentration of three posts in the test solution;
For the three samples in the test to the quality of the fraction w2, the value of%:
W2=(C1×V1×25)/m2 ×100
Where:
W2 -- mass fraction of triterpenoid in the test product,%;
C1 -- concentration of triterpenoid in test solution, in mg / ml;
V1 -- dilution volume of test solution in milliliters (ml);
m2 -- the amount of sample for the test, in milligrams (mg);
