Penentuan Wkatu Penyulingan dari Sereh (CY.M. Bopogon N. Ardus L. Rendle) untuk Memperoleh kadar Maksimal Minyak Atsiri

This research conduct to determination of Volatile Oil and citral level from lemon grass (Cymbopogon nardus L. Rendle) in the based of refening destillation time (1 to 4 hours). Destillation of Volatile Oil had been carried but by direct steam destillation and citral level was measured by Chromatography Gas. The results showed that refining destillation time give significant differential of Volatile Oil and citral level. Whereas the highest Volatile Oil (0,32%) and citral level (36,70%) showed at the first, and the lowest showed in the fourth (0,02% and 18,70%) of refining destillation time hours. In this observation showed that the increase of refining destillation time, give decrease of Volatile Oil and citral level.
