[Studies on the antitumour effect of Alocasia macrorrhiza]

Models of transplanted tumour in mice and human cancer enograft in nude mice were used to evaluate the antitumour effect of water extract of Alocasia macrorrhiza. Results showed that the inhibitory rate against S180 in mice was 29.38%, and the inhibitory rate against transplantable humman gastroadenitis in nude mice was 51.72%. No antitumour effect was shown against ECA in mice.
