The result showed that caffeic acid (PA4) and 3-O-coumaroyl-β-sitosterol (PE1) appeared to be most synergistic compounds for combining with other compounds and chlorogenic acid (PA6) was the most antagonistic compound with other compounds on the growth inhibition of A549, a human lung cancer cell line; while any 2-compound combinations of palmitic acid, 5-hydroxy-7-methoxy- 4'-acetylisoflavone and stigmasterol (S1) appeared to be synergistic on the growth inhibition HT-29, a human colorectal cancer cell line.

Thiol groups were good to be used in functionalizing gold nanoparticles, and ester bond formation and breakage played the major role in this research. Thioctic acid and 11-mercapto-1-undecanol were used to functionalize the gold nanoparticles and form ester bond by using the carboxylic acid group on thioctic acid and the hydroxyl group on 11-mercapto-1-undecanol. Concentrated sulfuric acid was used to be the catalyst in this reaction, and sodium hydroxide was added for the proceeding of the reverse reaction.
