Abstract: Abstract Having been stored under about 9 °C, air-proof condition for 24 months, the seeds of Elsholtzia bland a (Benth.) Benth can also keep their ger-mination up to 87%. The whole life of this plant from seeds to its ripeness and withered to yellow is 8-9 months. The essential oil content and chemical components of the wild plants collected from different ecological conditions varied obviously. The essential oil content of the plants growing under cultivated condition, shows a gradually increasing from 0.42% to 0.88%, along with the ripeness of the plant growth and development. There are some certain rules of variation with those main chemical components such as linalool, 1,8-cineol, phenyl alcohone, t-linalool oxide, comphor and borneol. Other components are less varied.
