Abstract

Erythrina plants, locally known as “dadap ayam”, are higher plant species and have been used as a folk medicine for treatment of cancer. To prove the effectiveness of the leaves and stem bark of E. variegata as an anti-cancer agent, the assay in this research was focused on in vitro  test  towards  breast  cancer  cell  T47D.  In  the course  of  our  continuing  search  for novel anti-cancer agent from Erythrina plants, the methanol extract of the leaves and stem bark of  E. variegata  showed  significant  anti-cancer  activity  against  breast  cancer  cell  T47D  in  vitro  using the Sulphorhodamine B (SRB) assay. By using the anti-cancer activity to follow the separations, the methanol extract was separated by combination of column chromatography. The chemical structure  of  an  anti-cancer  compounds  were  determined  on  the  basis  of  spectroscopic evidence  and  comparison  with  the  previously  reported  and  identified  as  an  erythrina  alkaloid (1)  and  isoflavonoid  (2).  Compounds  (1-2)  showed  anti-cancer  activity  against  breast  cancer cell  T47D  used  with  IC50  of    1.0  and  3.3  µg/mL,  respectively.  This  results  strongly  suggested that E. variegata is promising sources for anti-cancer agents.Keywords: Anti-cancer, Erythrina variegata, Leguminoseae

Abstract

The genus Aglaia is a a rich source of different compounds with interesting biological activities. A part of our continuing search for novel biologically active compounds from Indonesia Aglaia plants, the ethyl acetate extract of bark of Aglaia eximia showed significant antioxidant activity. Four antioxidant compounds, kaempferol (1), kaempferol-3-O-α-L-rhamnoside (2), kaempferol-3-O-β-D-glucoside (3) and kaempferol-3-O-β-D-glucosyl-(1→4)-α-L-rhamnoside (4) were isolated from the bark of Aglaia eximia (Meliaceae). The chemical structures of compounds 1-4 were identified on the basis of spectroscopic datas including UV, IR, NMR and MS along with by comparison with those spectra datas previously reported. All compounds showed DPPH radical-scavenging activity with IC50 values of 1.18, 6.34, 8.17, 10.63 mg/mL, respectively.

Abstract

Three flavonoid compounds, kaempferol (1), kaempferol-3-O-α-L-rhamnoside (2), and kaempferol-3-O-β-D-glucosyl-α-L-rhamnoside (3), were isolated from the bark of Aglaia eximia (Meliaceae). The chemical structures of compounds 1–3 were identified with spectroscopic data, including UV, IR, NMR (1H, 13C, DEPT 135°, HMQC, HMBC, 1H-1H-COSY NMR), and MS, as well as a compared with previously reported spectra data. All compounds were evaluated for their cytotoxic effects against P-388 murine leukemia cells. Compounds 1–3 showed cytotoxicity against P-388 murine leukemia cells with IC50 values of 1.22, 42.92, and >100 mg/mL, respectively
