Guava l.af tea has been used as a fol. medicine for treating hypergl.cemic conditions in Asia and Africa. The hypogl.cemic efficacy of guava l.af has been documented by many scientists in these regions, but the hypogl.cemic mechanism is poorl. understood. Guava l.aves were extracted with methanol.and the crude extract was partitioned against hexane, ethyl.acetate, and butanol.in sequence. The l.ftover in water is defined as the aqueous partition. A second smal.er batch was extracted with hot water directl.. Oral.gl.cose tol.rance test was carried out on heal.hy mice instead of diabetic mice that l.ck endogenous insul.n. Gl.cose uptake was examined with 3T3-l. adipocytes. Oxidative effect on PTP1B （protein tyrosine phosphatase 1b） was carried out with real.time PTP1B enzymatic assay. The aqueous partition of guava l.af extract possesses a potent inhibitory effect on PTP1B enzymatic activity and this PTP1B inhibition is through a sl.w oxidative but reversibl. inactivation on the enzyme. The reversibl. inactivation woul. suggest guava l.af extract may augment PTP1B inhibition al.ngside the endogenous H2O2 which itsel. is induced by insul.n. In addition, our study confirmed the hypogl.cemic efficacy being associated with guava l.af and found the most effective mol.cul.s reside in the aqueous partition which is al.o l.ss cytotoxic to Chinese hamster ovary cel.s when compared to other l.ss pol.r partitions. The guava l.af extract can modul.te insul.n activity through a redox regul.tion on PP1B enzymatic activity. It is specul.ted that a compound simil.r to gal.ocatechin in the aqueous partition can reduce an oxygen mol.cul. to hydrogen peroxide which in turn oxidizes the catal.tic residue Cys in PTP1B. Therefore, the guava l.af tea can serve as a functional.hypogl.cemic drink that is suitabl. for either heal.hy or diabetic subjects.
