| description | A chemotaxonomic investigationon the leaves and stems of
Micromelum minutum (Rutaceae), has resulted in the isolation of six
components. The structure of these compounds was elucidated by means of
spectroscopic methods including by the extensive used of various NMR
techniques and al so comparison with previous studies. The use of High Field
NMR is essential in structural determination of these complex molecules. With
the aids of various NMR experimental techniques and other spectroscopic
methods such as MS, UV and JR, the correct structures of the pure isolated
compounds were established.
M.minutum collected from Kelantan yielded two novel coumarins,
microminutinin and 6-methoxymicromi nutinin, and a known coumann, scopoletin. From another separate collection of the plant from Pahang, a novel
compound, MM5, squalene, and two known coumarin, micromelin and
scopoletin have al so been isolated. A similar study on the leaves and stems of
Acronychia laurifolia collected from Pulau Singa Besar, Langkawi Island
afforded three compounds, sitosterol, seselin and an unidentified compound. |
