*Different lowercase letters within the same column denote significant differences (P < 0.05)
**Different uppercase letters in the parenthesis within the same column denote significant differences (P < 0.05)
aValues are mean ± standard deviation (n = 3)
bPrior chlorophyll removal
cValues without and in the parenthesis were calculated with reference to the extract and brown lead seed (dry weight), respectively
