ABSTRACT
<p><b>AIM</b>To investigate the chemical constituents from Picria fel-terrae Lour.</p><p><b>METHODS</b>Column chromatography techniques were used to isolate the chemical constituents, physico-chemical constants and spectroscopic analysis were employed for structural elucidation. Results Two triterpenoids named picfeltarraenone I (1) and picfeltarraenin XI (2) were isolated, and their structures were established to be 3,11,22-trioxo-16alpha-hydroxy-(20S,24)-epoxy-cucurbit-5,23-diene (1) and 3,11,22-trioxo-16alpha-hydroxy-(20S,24)-epoxy-cucurbit-5, 23-diene-2beta-O-beta-D-glucopyranoside (2), respectively.</p><p><b>CONCLUSION</b>Compound 2 is a new compound, the 13CNMR data of compound 1 is reported for the first</p>
