2-Methoxyxanthone, 2-hydroxyxanthone, 4-hydroxyxanthone, 1-hydroxy-7-methoxyxanthone, 1,5-dihydroxyxanthone, 1,7-dihydroxyxanthone, 5-hydroxy-1-methoxyxanthone, 3-hydroxy-2-methoxyxanthone and a new natural product 2,6-dihydroxyxanthone have been isolated from the timber extractives of Mammea acuminata.A biogenetic pathway for the formation of xanthones is proposed.The occurence of the triterpenes glutinol and glutinone is reported for the first time from Guttiferae.
