Effect of microwave assisted extraction (MAE) on the phenolic content (TPC) and total flavoniod content (TFC) of three Malaysian plants curcuma longa linn (daun kunyit), syzygium polyanthum (daun salam) and diplazium esculentum (daun pucuk paku)

Total phenolic content and total flavonoidic content of six different extracts from the leaves of Syzgium polyanthum (daun samak), Curcuma longa (daun kunyit) and Diplazium esculentum (Daun pucuk paku) were estimated using spectrophotometric method. The phenolic content in 95 % confidential interval...
