The total poly phenolic content for red strawberry guava as reported by Luximon-Ramma and others (2003) was similar to that demonstrated in this study. The total flavonoid content, however was 71 mg/100 g of fruit, below the value found here (100.2 mg/100 g). On the other hand, in the case of yellow strawberry guava, the content of polyphenolic compounds was 563 mg/100 g of fruit, clearly above the value found in the present study (292.03 mg/100 g), while the flavonoids content was similar. According to Luximon-Ramma and others (2003) both strawberry guava fruits contain anthocyanins and other flavonoids. These observed difference may be due to variations in the maturity with which fruits are harvested and the site of collection. Furthermore, it is important to consider that in this study the cultivars of strawberry guava,which were used, had a higher transversal diameter (up to 3.5 cm) as compared to that of the native fruit (2 cm). Other researchers have noted that red strawberry fruits harvested at a mature stage showed a marked decrease in quality, characterized by lower soluble solids content (Drehmer and Do Amarant 2008). Casagrande Junior and others (1999) reported that a lack of sunlight can influence phenol levels in strawberry guava. In the present study, it was not possible to confirm the presence of anthocyanins by analyzing the chromatographic profile of yellow strawberry guava at 520 nm.
