Isolation and identification of the chemical constituents from the leaves of neobalanocarpus heimii / Mohd Amirul Safuan Abdul Jalil

Dipterocarpaceae is one of plant families that exist in Malaysia whereby it consist of a large number of plant species. The aims of this project were to isolate and identify the chemical constituent from the leaf of Neobalanocarpus heimii or also known as chengal. Besides that, this project will only focus on identifying any compound which derived from stilbene. Preparative of High Performance Liquid Chromatography (HPLC) was used to isolate and purify oligostilbene compound. The purified compound was then analyzed using NMR spectroscopy to identify the compound structure and stereochemistry. The NMR spectrum was then compared with the reported data from journals to identify the identity of the compound. The result shows that the leaves extract of Neobalanocarpus heimii contain oligostilbene which is vaticanol A.
