Snails (Pomacea canaliculata Lamarck) is one type of freshwater snails which comes from the Americas. Snails have become a serious threat in agriculture due to high reproductive power and capability of rapid deployment area. This research result of chemical composition showed that golden snail egg contain to high moisture and fat. Golden snail eggs have a high total carotenoids is 313.48 ± 19.73 ppm. This research aims to optimize the extraction process of carotenoids with different types of solvents. Golden snail eggs, chopped and mashed in a blender then dried by the method of freeze dry for 58 hours. After getting the golden snail eggs, egg powder snails do multilevel extraction method using n-hexane, acetone and methanol in the ratio 1: 10 (w / v) and extracted with maceration for 24 hours. Furthermore, the single extraction with solvents methanol 1: 10 (w / v), ethanol 1: 10 (w/v), acetone: methanol with a ratio of 3: 7 and acetone: distilled water with a ratio of 3: 15 (w/v) method maceration for 48 hours. Results extraction then evaporated and the result filtrate diluted with methanol measured using a spectrophotometer to see the absorption wavelength. The optimum solvent extraction golden snail eggs is a polar solvent to extract the highest acetone: distilled water with a ratio of 3: 15 namely 1084.6 mg.
