title: Two new Anti-TMV active chalconoid analogues from the root of Phyllanthus emblica.
abstract: Two new chalconoid analogues, emblirol A (1) and B (2), along with three known ones (3-5), were isolated from the root of the Phyllanthus emblica L. Their structures were elucidated on the basis of spectral data. Compound 1 and 2 showed moderate anti-TMV activity with inhibition rates 79.6 and 62.1% at a concentration of 1 mg/mL, respectively.
