Extraction was soaked by the principle of spreading slurry into the matrix of the sample. This method is often used in conjunction with high temperatures to increase efficiency. Tissue samples will make a significant weakening pattern can break into the sample matrix and melted into a compound in the sample solution. In addition, the method also takes a long time to extract. The higher temperature and longer duration may affect the extraction of natural compounds that are not stable to heat or oxygen. The results showed that when the oil is extracted from papaya seeds by soaking conditions at temperature 57.51 ° C, time 9 hr, and sample to solvent ratio 1:20 v / w, which is considered as the best condition. And gave yield. 29.14%
