This study was carried out to determine the physico-chemical properties of oil from three Jatropha curcas provenances from Mexican and Asian origins. The oil yield of three Jatropha curcas provenances was high, ranging from 35-50 %. Tubao- PhilBio got the highest oil yield with 50.77%, followed by Indian D1 oil with 48.21% and Mexican -PhilBio with 35.90%.Indian D1 oil has the highest acid value having 18.70 mL KOH / g Tubao- PhilBio with 15.43 mL KOH / g and Mexican- PhilBio was the lowest with 13.09 mL KOH/g The peroxide values of three provenances were 29.76meq / g from Indian D1, 28.69meq/g from Mexican- PhilBio and 25.76meq / g from Tubao-PhilBio an indication that Indian D1 has greater rancidity. The iodine value of three provenances of three Jatropha curcas in this study namely Tubao- PhilBio, Mexican- PhilBio and Indian D1 was 111.76 12/g, 109.77 l_{2} / g and 114.46I_{2} / g respectively. The density of the three provenances was similar to the standard value reported by EN14214 ranging from 0.86 - 0.93g / c * m ^ 3 is a significant difference among the three Jatropha curcas provenances in terms of oil yield, acid value, refractive index and viscosity. In terms of peroxide value, iodine value and density, the study shows no significant difference.
