Extraction of tannin from Eucalyptus camaldulensis Dehnh. and trimyristin from Myristica fragrans Houtt. by using microwave irradiation

Here in reported the application of Hot Extraction Filtration (HEF) apparatus by Microwave system and combination of Microwave- heating and steam distillation as a new technique under the optimal condition in the extraction of trimyristin from Myristica fragrans Houtt. and tannin from Eucalyptus camaldulensis Dehnh. leaves. Microwave irradiation-HEF were at 700 w for 10 min at 120 °C in order to extract trimyristin and steam distillation- microwave irradiation at 300 w for 30 min for extraction of tannin were evaluated. The extracted products were isolated and identified by FT-IR, HPLC, *H-NMR and 13C-NMR. This method compared to the conventional heating method provided a fast and easy procedure. Also high yield and increasing the purity of crude extract products is the advantages of this procedure.
