  A new anthraquinone glycoside was isolated from the hydrophilic fraction of the Chinese medicinal plant Rhynchotechum vestitum. Its structure was determined as damnacanthol-11-O-beta-glucoside by spectroscopic evidence. The occurrence of rubiadin-1-methylether-3-O-beta-primeveroside, lucidine-3-O-beta-primeveroside and rubiadin-3-O-beta-primeveroside in the plant is reported for the first time.

  A reinvestigation of the whole plant of Andrographis echioides has led to the isolation of a new flavanone, dihydroechioidinin together with four known flavones, echioidinin, echioidin, skullcapflavone I 2'-O-methyl ether, and skullcapflavone I 2'-O-glucoside. The structure of dihydroechioidinin was established as (2S)-5,2'-dihydroxy-7-methoxyflavanone on the basis of spectral and chemical evidence.
