The rice was submerged for 6 hours so the mouisture increased to 30%. It was cooked in an autoclave at 116 ^oC for 15 minutes. The cooked rice then it was dried at 50 oC for 24 hours. This method didn’t have effects on reducing glycemic index but it increased the glycemic index higher than 54, e.g. 56 by tester 1 and 80 by tester 2.

In the present study, phytochemical screening of ethanolic extracts of Azadirachta indica leaves from Indonesia and the Philippines revealed the presence of different phytoconstituents. Preliminary qualitative chemical test, TLC and LC-MS were used. TLC for all the extracts showed bands in long UV 366 for presence of flavonoid, tannin, saponin, terpenoid. As a result of LC-MS analysis of ethanolic extract Azadirachta indica leaves from Indonesia and Philippines, 10 compounds from Indonesian varian and 7 compounds from the Philippines varian were detected using m/z value. In conclusion, phytochemical screening based on TLC and LC-MS/MS show diverse bioactive compounds in ethanolic extract Azadirachta indica leaves from Indonesia and the Philippines. These can be effective approach for selecting best quality of varian leaves and planting area.
