SPECTROSCOPICALSTUDYOF AN ETHER FRACTIONISOLATE FROM STEAM BARK OF" JATI" (Tectona grandls, L)

ABSTRACT This research is aimed to primarily study the spectroscopy of ether fraction of from Jati wood (T. grandis, L). The stem bark of T.grandis, L was firstly extracted undergoes a ranux in methanol solvent. Further, the dried methanol crude extract was extracted with diethyl ether and moreover...
