The potency of java plum (Syzgium cumini) fruit extract as free radical scavenging in cigarette smoke

This research aimed to prove the ability of extracted freeze-dried java plum fruit applied with a cigarette filter to decrease the intensity of free radicals in the cigarette smoke. It was reported that there was a difference in the spectrum infrared (IR) pattern, leading to a wavelength shift in the smoke burning from a cigarette after the application of the freeze-dried java plum fruit extract on its filter (K1). The XRD analysis indicated that were some diffraction peaks found in K1. This finding suggested that java plum fruit was able to alter the structure and the position of atoms found in the cigarette. In addition, the result of ESR analysis showed that K1 was less paramagnetic than the commercial cigarette smoke (K0). The difference in factor-g value between the K0 and K1 caused an energy splitting, where the commercial cigarette smoke (K0) generated higher factor-g value. The g-factor value was 2.009 and 2.0048, respectively. Furthermore, the ESR spectra indicated a decline in the intensity of free radicals found in K1. Findings of this research, therefore, suggest that the extract of freeze-dried java plum fruit is effective in decreasing the intensity of free radicals in cigarette smoke.This research aimed to prove the ability of extracted freeze-dried java plum fruit applied with a cigarette filter to decrease the intensity of free radicals in the cigarette smoke.
