notable that Phyllanthus flexuosus produces a wide variety of modified
dehydroellagitannins, including 28 , phyllanthusiins A ( 32 ), B ( 33 ), and C
( 34 ) (Yoshida et al. , 1992a), repandusinic acid A ( 35 , Saijo et al. ,
1989a), ascorgeraniin (= elaeocarpusin) ( 39 , Tanaka et al. , 1986b, Okuda
et al. , 1986), putranjivain A ( 40 , Lin et al. , 1990). Other analogous
tannins and their plant sources are listed in Table 2.2; eumaculin E ( 31 ,
Amakura et al. , 1997), mallotinin ( 36 , Saijo et al. , 1989b), bixanin ( 37 ,
Lee et al. , 1990b), amariinic acid ( 38 , Foo, 1995), geraniinic acid ( 41 , Ito
et al. , 1999a) and euphormisin M 2 ( 42 , Yoshida et al. , 1994) (see also
