Abstract A novel taraxerane-type triterpene-diol, in addition to taraxerol and lupeol, was isolated from the leaves of Parsonsia laevigata . Its structure was shown to be (4β)-D-friedoolean- 14-ene-3β,24-diol (taraxer- 14-ene-3β,24-diol) by a combination of chemical and spectroscopic methods.

Abstract A novel pyrrolizidine alkaloid, 3′-acetylindicine-N-oxide {[1R-[1α, 7(2R∗,3S∗), 7αβ]]-3- acetoxy-2-hydroxy -2-(1-methylethyl)-butanoic acid (2,3,5,7a-tetrahydro-1-hydroxy-1H-pyrrolizin-7-yl)methyl ester N-oxide}, was isolated from the twigs of Messerschmidia argentea, in addition to 3′-acetylindicine, indicine and its N-oxide. Structures of these alkaloids were determined by spectroscopic methods and from chemical evidence.
