Hi Surendra,

I don´t known if this article can help you, but take a look.

Have a good work

Oh dear! it depends on ones own approach, soxhlet extraction method saves time and assure the maximum recovery of the target, if is it not heat sensitive. For lutein use petroleum ether and acetone in 1:1 ratio or you may try dichloromethane as extracting solvent in soxhlet method, and no issue if you latter analyze through HPLC, TLC  

The brief steps are:

First of all you isolate the pure fraction from plant extracts using following techniques. First run TLC to know the type of fractions. After that Column Chromatography with HPLC, after isolated pure fraction run FT-IR, LC-MS, HNMR, CNMR for structure elucidation. You can read my papers too.

in soxhlet  you can use different solvent for polar and nonpolar

for Polar: water, methanol, ethanol

for Non-polar: hexane

Soxhlet is a simple method of lutein extraction. FT-IR is used to eucidate the structure of lutein.
