“…The ethanol bark extract yielded chloroform-soluble and water-soluble bases, identifi ed as erysovine and stachydrine, respectively. From the bark were isolated isofl avones (erythrinins A,B, C, osajin; alpinumisofl avone; and oxyresveratrol and dihydrooxyresveratrol) (Deshpande et al 1977 ), alkaloids (erysotine, erythratidine, epi -erythratidine and 11-hydroxy-epi -erythratidine) (Chawla et al 1988 ), three fl avonoid phospholipase A 2 (PLA 2 ) inhibitors (4′-hydroxy-3′,5′-diprenylisofl avonone (abyssinone V) and 3,9-dihydroxy-2,10-diprenylpterocarp-6a-ene (erycrystagallin) and 4′-hydroxy-6,3′,5′-triprenylisofl avonone) (Hedge et al 1997), erythrinin B ( Kobayahsi et al 1997, alpinumisofl avone and two prenylated isofl avones (erythrivarones A and B characterized as dihydroalpinumisofl avone and 4′-hydroxy-[6″,6″-dimethyldihydropyrano(2″,3″:5,6)]-[6‴,6‴-dimethyldihy dropyrano(2‴,3‴:7,8)] isofl avone, respectively) (Huang and Yen 1996 ; and warangalone (Huang and Tseng 1998 ). Isofl avonoids, eryvarin A and eryvarin B, were isolated from wood (Tanaka et al 2000 ).…”
