Abstract :

The present work was taken up to compare the phytochemical and antioxidant properties of two guava cultivars being sold in the local markets of Central India, the local cultivar and the Thai cultivar, which is produced by grafting method. The results showed that the Thai cultivar has lower amountys of phenolic compounds, i.e. flavonoids, anthocyanins, tannins and triterpenes as compared to the local fruit cultivar. Further, the amount of antioxidant activity against reactive oxygen species and DPPH was also lowered in Thai cultivar, stating that this grafted varieties has less potential to scavnege free radicals and combating diseases.
