title: A new triterpenoid from the rhizomes of Nelumbo nucifera.
abstract: A new triterpenoid, 2α,24-diacetoxy-3β-hydroxyolean-12-en-28-oic acid (1), was characterised from the rhizomes of Nelumbo nucifera Gaertn by spectroscopic and chemical methods along with four known compounds, hyptatic acid-A (2α,3β,24-trihydroxyolean-12-en-28-oic acid) (2), maslinic acid (2α,3β-dihydroxyoleane-12-ene-28-oic acid), betulin and lupeol.
