A new anthraquinone from the root of Lasianthus acuminatissimus

To study the constituents from the chloroform extract of the roots of Lasianthus acuminatissimus Merr., various chromatographic techniques were used to separate and purify the constituents. The structure was established on the basis of 1D, 2D NMR and HRMS spectroscopic analysis. A new compound was isolated and identified, which was 3,8-dihydroxy-1-methoxy-2-methoxymethyl-9,10-anthraquinone (I). Compound I is a new anthraquinone, namely lasianthurin.
