  A comparative study of the phenolic products in the heartwood of Acacia karroo from two different localities

  摘要：

  Known flavonoids were found in the heartwood of Acacia karroo. New natural products were isolated from the proposed subspecies montana. They are (2'S,3'R)-3,10-dihydroxy-9-O-(6'-hydroxy-7'-O-methyl-2'-hydroxy- methyldihydrobenzo furan-3-yl)dibenz-[b,d]-pyran-6-one and its 10-O-methyl analogue; 8-O-methylepiprosopin-4 beta-ol; 8-methoxyfustin; and 7,8,3,4'-tetrahydroxy-3'-methoxyflavone. Apart from the difference in substitution patterns of the compounds isolated from the two plant sources, the flavonoids from subspecies montana are O-methylated as opposed to none occurring in A. karroo.
