Sesquiterpenoids from the Rhizomes of Homalomenaocculta
ABSTRACT: Naturally occurring oplopanane sesquiterpenoids are rarely reported. A phytochemical investigation on the rhizomes of Homalomena occulta (Lours) has resulted in the discovery of six oplopanane sesquiterpenoids (1–6), including four new (1–4) and one 3,5-seco-oplopanane (6), together with t...

description | ABSTRACT: Naturally occurring oplopanane sesquiterpenoids are rarely reported. A phytochemical investigation on the rhizomes of Homalomena occulta (Lours) has resulted in the discovery of six oplopanane sesquiterpenoids (1–6), including four new (1–4) and one 3,5-seco-oplopanane (6), together with three previously reported sesquiterpenoids (7−9). In addition three new oplopananes (2a–4a) were also obtained by chemical transformation. All structures of these sesquiterpenoids were established based on the comprehensive spectroscopic analyses, including NMR, MS, and IR, and comparing with the literatures.
