Climatic gradients were based on data sets from 841 meteorological stations throughout China. Definitions for floristic distributional patterns were based upon the work of Prof. Z. Y. Wu. Most of these floristic distributional patterns were strongly correlated with the geographic gradients in climate, except for cosmopolitan, cultivated and invasive genera. Tropical genera form a large fraction of the total genera (ranging from 0.84% to 94.38% in the regional floras) with the highest proportion in southern Yunnan and Hainan Island. Tropical genera occur predominantly in southern China of 0° N latitude and decreased with increasing latitude, as would be expected. Interestingly, the disjunct Tropical Asia and Tropical America distribution were not restricted to southern latitudes. Temperate genera account for 5.1% to 98.83% of the total genera in regional floras with the highest proportion in the province of Xinjiang. Most of these genera followed geographic gradients in climate as expected (temperate genera conspicuously dominate the landscape at higher latitudes), except the East Asian and North American disjunct distribution, Eastern Asian distribution and Chinese endemic distribution. Generally, most plant genera demonstrated some correlation with climatic and geographic gradients. The most important gradients were those of annual air temperature and precipitation. A small fraction did not demonstrate significantly particular pattern:"Cosmopolitan","East Asian and North American disjunct","Eastern Asian" and "Chinese endemic" distributions. The North Temperate distribution had the highest correlation with mean annual air temperature and precipitation.

A new technology, Supercritical Fluid CO_2 Extraction, was also supplied to study the plant. The technological parameter was optimal. Total extract of SFE-CO_2 were 4.86 times of the essential oil extracted by SDE, main active extracted constituents were 1.36% high than SDE. The chemical constituents of SFE-CO_2 were also analyzed by GC-MS. 57 constituents were identified, 29 constituents of them were first discovered. 24 constituents were discovered in two extract. Fingerprint is a good technology to elevate the quality of herb medicine. The main active fraction can be extracted by SDE and SFE, Fingerprint was studied respective, chromatographic parameter was acquired. 22 peaks were assigned common peaks in the spectrum of essential oil, 17 peaks were assigned to common peaks in the spectrum of SFE extract.
