a

Concentrations were determined by LC - MS analysis of extracts prepared from the relevant plant parts. Standard deviations are for triplicate analyses of the same extract. Extract concentration was calculated based on linear regression analysis of 6 point calibration curves of peak area versus concentration with slope (m) = 587881 ± 4628, intercept (b) = −20512 ± 10554, and R2 = 0.9998 for sesamin and a slope (m) = 647726 ± 16450, intercept (b) = −15594 ± 37516, and R2 = 0.9974 for asarinin. Extracts were diluted so that the concentrations tested fell within the linear range of the calibration curve.

b

Yield is reported as parts per thousand or mass of pure compound (g) per mass of original plant material (kg).

c

% in extract is reported as mass (g) of sesamin or asarinin per mass of solid extract (g) × 100.

The % in extract values are provided for the purpose of comparison with biological data.
