RESUMO
Objective To lay the foundation of new botanical pesticides by screening the insecticidal efficacy of 10 commonly used TCM pesticides.Methods Slide immersion method, trace intravenous drip method and insect body dipping method were respectively used to measure contact action of water extract and ethanol extract of the 10 commonly used TCM pesticides toTeranychus cinnbarinus,Brevicoryne brassicaeandMythimna separate, with herbal extracts to three kinds of insect pests of corrected mortality as observation indexes,Results Alcohol extracts for three kinds of insect pests were found to have contact action, and water extracts had no obvious effect. The Stemonae Radix alcohol extract had obvious contact action on three kinds of insect pests, and corrected mortality rates were 78.7%, 85.9%, and 96.7%, respectively; ethanol extracts of Angled Bittersweet, Sophorae Flavescentis Radix, Xanthii Fructus and Kansui Radix showed good contact action to Teranychus cinnbarinus,. The volume ratio of compatibility among Angled Bittersweet, Sophorae Flavescentis Radix, Xanthii Fructus and Kansui Radix was 2:1:1.5:1.5:1.5:1.5. The insecticidal activity to Teranychus cinnbarinus, was stronger than extracts of single herbs, and corrected mortality was 96.5%. Alcohol extracts of Stellera, hellebore, white mustard seed, and Xanthii Fructus showed good contact action toBrevicoryne brassicae. When the volume ratio of compatibility among Xanthii Fructus, Stemonae Radix, Stellera, and hellebore was 1:1.5:2:2, the activity toBrevicoryne brassicae increased. and corrected mortality was 93.1%.Conclusion The insecticidal activity will be enhanced after TCM extracts are under compatibility.
RESUMO
Objective To compare analgesic and anti-inflammatory effects of Gentianopsis Paludosa and Sophora Alopecuroide of different kinds of compatibility on the mice.Methods Mice were randomly divided into normal control group, positive medicine group, and different kinds of compatibility groups, 10 mice in each group. Mice received gavage for successive 7 days, once a day. Glacial acetic acid twist body method and hot board to pain method were used to observe and compare analgesic effects of different kinds of compatibility. Xylene to ear swelling method and agar to granulation swollen method were used to observe and compare inflammatory effects of different kinds of compatibility.Results Compared with normal group, compound Gentianopsis Paludosa had obvious analgesic and anti-inflammatory effects (P<0.01). When the ratio of Gentianopsis Paludosa and Sophora Alopecuroide was 20:0.6 and 20:0.9, the analgesic and anti-inflammatory effects were the best.Conclusion Gentianopsis Paludosa and Sophora Alopecuroide have good analgesic and anti-inflammatory effects, among which, when the ratio of Gentianopsis Paludosa and Sophora Alopecuroide is 20:0.6, the best effects show.
