Antifungal compounds in Thai mango fruits latex
Anthracnose disease is the major postharvest disease of mango fruits in
Thailand. This pathogen cause by
Colletotrichum gloeosporiodes, which infects the fruits before harvesting, and the symptoms appeared later. Antifungal compound from each part of mature green of Thai mango fruits was investigated. Preformed antifungal compounds were detected in the peel and latex extracted in dichloromethane fraction by using thin layer chromatography (TLC) and bioassay. The active compound in latex showed the same Rf as found in the peel, which has been identified as resorcinol derivatives. The active compounds are being purified and identified by using preparative TLC, UV-spectrophotometer and gas chromatography mass spectrometry.
