Abstract

Calyptothecium ramosii Broth. of the moss family Pterobyaceae is a species indigenous to the Philippines. Chemical investigation of the dichloromethane extract of C. ramosii has led to the isolation of γ-polypodatetraene (1), cinnamic acid (2) and saturated long-chain hydrocarbons (3).  The structure of 1 was elucidated by extensive 1D and 2D nuclear magnetic resonance spectroscopy (NMR) and confirmed by comparison of its NMR data with literature data. The structures of 2 and 3 were identified by comparison of their NMR data with literature data.

 

Keywords:     Calyptothecium ramosii Broth., cinnamic acid, long-chain hydrocarbons, γ-polypodatetraene, Pterobyaceae

 

Abstrak

Calyptothecium ramosii Broth. ialah lumut dari famili Pterobyaceace merupakan spesies asli bagi Filipina. Kajian juzuk kimia dilakukan ke atas ekstrak C. ramosii menggunakan diklorometana untuk memisahkan γ-polipodatetraen (1), asid sinamik (2) dan hidrokarbon tepu rantaian panjang (3). Struktur 1 telah dicirikan melalui spektroskopi nuklear magnetik resonan 1D dan 2D dan ditentusahkan melalui perbandingan data kajian literatur dan data NMR.

 

Kata kunci:     Calyptothecium ramosii Broth., asid sinamik, hidrkarbon rantaian panjang, γ-polipodatetraen, Pterobyaceae
