Hi guys, i need you help. I'm new here, But i really need your help.

 I'll ask this directly. What are the physical and chemical characteristics  of oil from (Jatropha curcas) and Moringa Oleifera? What are the existing methods in determining these values? Which of the methods can be done cheaply? I would really appreciate all your help greatly..

Thanks!

This site has a section which describes a method for determining the acid number.

You could also look at this paper, which gives a list of all the standards and methods that they used. Unfortunately, it is just a list and it doesn't decribe anything in detail. However, at least you will then be able to look them up.
