Optimization and effect of supercritical carbon dioxide extraction conditions on global oil yield and eugenol from piper betle leaves

Todays, medicinal plants have been of great importance to the health of people and societies in Malaysia, and the entire world. Piper betle leaves, a member of family Piperaceae is an edible plant. The leaves of Piper betle have been traditionally utilized in India for inhibition of oral diseases. S...
