Samples were taken at 10 min time intervals and
analyzed by TLC (eluent chloroform/petroleum ether,
1:3 ratio) to check the conversion to biodiesel. TLC was
chosen as a rapid analytical method and it gives quite
accurate indication of oil and biodiesel content in the
mixture After purification the biodiesel was analyzed
using a Shimadzu GC-MS Model QP-2010, equipped
with a DB-5 capillary column (0.53 mm· 30 m) J&W
