In the research, major distribution areas of key plants were investigated and statistical work was made on plant species. The results show that aromatic plant species can be classified into over 170 species in 43 families, with 26 key families. In addition, the application of the plant species was il ustrated and some suggestions were proposed as wel .展开更多

The fresh osmanthus flower was processed with a petroleum ether digestion method to produce the extractum. The yields of essential oil and extractum were 0.19 % and 0.13 % （m/m） respectively. The essential oil and fragrance composition and content extracted were analyzed with gas chromatography-mass spectrometer （GC-MS）. The result showed that essential oil contained 36.99%（area/total area） of ionone, ionol and 13.11% of linalool; ionone and ionol contained in extractum were as high as up to 33.33%, while linalool up to 21.92%. Whether essential oil or extractum contains only about 40% fat acid and other ester matters. None of environmental estrogen （phthalic ester） was found in fragrance ingredients. The result also showed that the quality of O. fragrans Albus group fragrance in Xianning is better than that produced in Hangzhou and Anhui districts.展开更多

The results show that chronic prostatitis is markedly improved by using Qian Lie Xian Yan suppository, with a short-term cure rate of 23.1% and a total effective rate of 84.6%, superior to that of the control group. The animal experiment indicates that Qian Lie Xian Yan suppository has better anti-inflammatory and analgesic effects, with an action of promoting blood circulation.展开更多
