Erianin (Standard) is a reference standard for research and analysis in studies involving Erianin. Erianin is a nature product extracted from Dendrobium chrysotoxum, has notable antitumour activity , can cause extensive tumour necrosis, growth delay. Erianin has antiangiogenic action by inhibiting endothelial metabolism in a JNK/SAPK-dependent manner and inducing endothelial cytoskeletal disorganisation. Erianin shows potent inhibitory activity on the proliferation of HL-60 cells, the inhibition might be relative to the apoptosis induced by Erianin and the altered expression of bcl-2 and bax genes in HL-60 cells.
