“…Due to their easy use and speed, silica-gel coated TLC plates have already been used for qualitative determination of lupeol, a-, and b-amyrin (Dalvi et al 2007). Moreover, TLC analysis allows a large number of samples to be analyzed simultaneously.…”

Emerging technologies are being explored to improve extraction yields of phytochemicals or high-value biological compounds. The aim of this study was to evaluate the extraction of lupeol, α-, and β-amyrin from fruit, leaf and stem of the sea grape tree ( L.) using technologies such as Ultrasound Assisted Extraction (UAE) and High Hydrostatic Pressure Extraction (HHPE). Results were compared to conventional extraction (maceration). Analysis with thin-layer chromatography revealed the presence of lupeol in all studied parts of the tree. Optimal extraction conditions for UAE and HHPE were found; the highest concentration of triterpenes was obtained by UAE after evaluating conventional and non-conventional techniques. Finally, analysis of different tree parts and other vegetable sources showed that the best source of triterpenes was the leaf.
