Abstract

Leutin is a plant-derived compound and non-vitamin A carotenoid. Leutin cannot be synthesised by humans and hence obtained by the ingestion of foods viz., fruits and vegetables. It possesses multiple protective properties like anti-cancer, anti-inflammation, and hepatoprotection and also helps in the prevention of age-related maculopathy, cardiovascular diseases, diabetes etc. Leutin content in fresh noni leaves and the leaves dried after three different treatments viz plain dried without treatment, steam blanched and hot water blanched were assessed. For this study, availability and procurement of noni leaves was challenging since only tender leaves were used. Leutin concentration could vary due to several factors like variety, stage of maturity, growing climatic conditions etc. In this study, two different solvents viz acetone and butanol were used for extraction. The study shows drying has a positive effect on the leutin concentration of noni leaves specifically in acetone than butanol extraction. the leutin concentration increased in acetone extraction from 0.067 μg/g to 0.096 μg/g from zeroth hour to ninth hour respectively than other treatments.

Leutin, noni leaves, fresh, Pretreatment, dried, acetone, butanol

Conclusion

The study concludes that drying of noni leaves by different prior treatment, particularly steam blanched has positive effect on the leutin concentration than that of other treatments and fresh noni leaves. The solvent used for extraction plays a major role in the yield obtained. Hence it is suggested that the selection of appropriate method of treatment and solvent for extraction is important for further study of this compound.
