Abstract
This study was conducted to investigate chemical properties of wild Lactuca indica (WL) and cultivated Lactuca indica (CL). The proximate composition, reducing sugar, free amino acids, organic acid, vitamin C, minerals, chlorophyll, and crude saponin were analyzed. WL and CL contained high levels of carbohydrate. The leaves and roots of CL contained higher levels of free amino acid than those of WL. Especially, the proline content of CL leaf was 12 times higher than that of WL leaf, and the arginine content of CL root was 100 times higher than that of WL root. The major organic acid and mineral of Lactuca indica were tartaric acid and potassium, respectively. CL showed significantly higher value of reducing sugar than WL. The vitamin C content of the samples ranged from 0.4 to 24.1 mg%, and CL leaf was the highest amount of vitamin C among the samples. CL leaf had a higher amount of chlorophyll than WL leaf, but WL root contained a higher amount of crude saponin than CL root. As in this study, CL showed better nutritional properties than WL, and these results will provide fundamental data in order to activate the cultivation of wild plants.
