Runanine (17) was isolated from the roots of Stephania sinica, a species found in the Chinese provinces of Heibei, Gueizhou, and Yunnan (35). The H-NMR spectrum of runanine (17) (Table II) revealed the presence of two aromatic protons, C-5 methylene protons, one N-methyl, and four methoxyl groups. An NOE effect (10% enhancement) was observed between the protons of two methoxyl groups (53.79 and 3.80) and the aromatic protons (56.47 and 6.64), but the same phenomenon was not observed for the other methoxyl protons (53.61 and 4.05). Therefore, the former methoxyls should be situated on ring A. From the further observation of an NOE (22.6% enhancement) between the aromatic C-4 proton (56.64) and one (53.00) of the C-5 methylene protons, it was assumed that the two methoxyl groups (53.79 and 3.80) should be located at C-2 and C-3, respectively. The absence of signals for olefinic...

The cultivation and enjoyment of tea are recorded in Chinese literature of 2700 BC and in Japan about 1100. Through the Arabs, tea reached Europe about 1550. Native to Assam, Burma, and the Chinese province of Yunnan, it is highly regarded in southern Asia and planted in India, southern Russia, East Africa, Java, Ceylon, Sumatra, Argentina, and Turkey. China, India, Indonesia, and Japan produced about a half of the total world production.

From Myanmar to China trafficking along this route has increased. In 2006, the Chinese authorities reported some 55 per cent of their total methamphetamine seizures as having taken place in Yunnan province bordering Myanmar, a significant increase from 18 per cent in 2002.

After 1983, the Standing Committee of State Council decided to stop the application of DDT in agriculture. Thereafter, DDT was mainly used as a raw material to produce Dicofol, with a small portion consumed as raw material to produce paints, as additives to produce mosquito-repellent incense, and to prevent malaria. The Chinese Center for Disease Control and Prevention (CDC) has decided that DDT can be used in closed systems and indoor sites in small amounts to control disease vectors, but its outdoor use is forbidden to prevent pollution. Malaria control in China has been effective, and DDT has not been used by local CDCs since 2001. The sale and consumption of DDT in 2001 and 2002 are shown in Table 3.4. It is seen that 83.9% of DDT produced was used to produce Dicofol 8.5% of that was exported for malaria prevention, 2.5% was used to produce mosquito-repellent incense, and 3.9% was used to produce paints. The investigation of consumption in 10 provinces and cities of China indicates that DDT is no longer used for agriculture or termite control, and a small portion of DDT is still used to prevent malaria. For example, 380 MT of DDT was used to control malaria between 1997 and 2000 in Yunnan province. 

In addition, in the sanitation field, Shanghai, Jiangsu, Yunnan, Shanxi, and Guangxi once used mirex to kill domestic ants. There are no records of import and export of mirex after 1998.
