An investigation of phenolics inMelicoccus bijugatus Jacq. ‘Montgomery’ variety fruit tissues.

The fruits of the native South American tree Melicoccus bijugatus Jacq., also known as Spanish lime, are consumed both for their dietary and medicinal value. Limited information is available on the phytochemical content and biological activities of either wild or cultivated varieties of M. bijugatus fruits. The ‘Montgomery’ variety is a popular variety grown in Florida with several desirable fruit qualities, which include large size, high pulp content (51.5%), good flavor, and high fruit yield. In this study several phenolics in the ‘Montgomery’ variety fruits were identified from methanol extracts of pulp, embryo and seed coat tissues by using reverse phase high performance liquid chromatography (HPLC) and tandem mass spectrometry (LC/MS/MS). A HPLC fingerprint of each tissue was obtained at 280nm and several peaks in this profile were identified. The results of this study indicated mostly phenolic acids in the pulp tissues of the fruits. In the embryo tissues, phenolic acids, flavanoids and procyanidins and catechins were identified. On the other hand, seed coat tissues appeared to have more procyanidins then the embryo tissues and several prodcaynidin trimers were also observed. Overall, the results of this study provided new information on the phytochemical content of this particular variety of M. bijugatus fruits. However, further studies should be done to compare the phytochemistry and biological activity of some of the other varieties and wild species of theM. bijugatus fruit tissues to evaluate which varieties and phytochemical components are likely to have the most beneficial health effects.
