A phenalenone-type phytoalexin from Musa acuminata.

ABSTRACT :

 

The unripe green fruits of banana (M. acuminata (AAA) cv. Giant Cavendish) are resistant to infection by Colletotrichum musae. Green fruits were inoculated with conidia of the fungus, and incubated for 6 days at 24 deg C. Four antifungal compounds were detected in fruit extracts. The 2 major compounds were identified as 2-(4'-hydroxyphenyl)-naphthalic anhydride and methyl 2-benzimidazole carbamate, from spectral data. The former is a new phytoalexin of the phenalenone type, and the latter is an antifungal agent derived from benomyl, a postharvest fungicide, but behaving like a phytoalexin.
