Pharmacological action [ ]
1central inhibition of1.1sedative and anticonvulsant effect of essential oil of Abies NEPHROLEPIS Maxim1.70ml / kg,0.85ml / kg,0.425ml / kg were given to mice, can significantly reduce the spontaneous activities of mouse, very significant increase in sodium pentobarbital sleeping time and subthreshold dose sleep rate, sedative effect site in the brain stem; on pentylenetetrazol induced convulsions and seizures have evident antagonism, but to caffeine, strychnine-induced convulsion in mice without obvious effect.
1.2. The analgesic and antipyretic effects of essential oil of 1.70ml / kg,0.85ml / kg gavage can significantly increase the mice to thermal stimulation threshold, reducing the acetic acid-induced writhing reaction in mice; oil of carrageenan and yeast suspension induced fever in rats have very significant inhibition,1.70ml / kg gavage can significantly reduce the normal body temperature in rats.
Antitussive, expectorant and antiasthmatic effects of2essential oil of Abies NEPHROLEPIS Maxim1.7ml / kg,0.85ml / kg / day intragastrically, on 4 consecutive days, the ammonia stimulates respiratory mucosa in mice caused by coughing showed significant inhibition; phenolsulfonphthalein excretion test, oil can make tracheal secretory liquid volume increase, the sputum thinning, there was significant expectorant effect; can obviously increase the Columba Livia trachea cilia moving; to acetylcholine and histamine phosphate induced in guinea pig asthma has a significant inhibitory effect.
3the anti-inflammatory effect of essential oil of Abies NEPHROLEPIS Maxim1.04ml / kg,0.52ml / kg gavage on various inflammatory agent ( carrageenan, egg white, histamine, serotonin (5-5-HT ), prostaglandin E1( PGE1), nystatin ) induced rat paw swelling had significant inhibitory action, carrageenan induced paw edema1.04ml / kg with80mg / kg ibuprofen quite clear, and there is obvious dose-effect relationship,0.85ml / kg on croton oil and gas cyst exudate and granuloma hyperplasia respectively by 85.9% and30%, carrageenan induced pleurisy, pleural exudate within the total white blood cell count. Histamine and 5-HT induced capillary permeability, carrageenin paw edema inflammatory exudate in the synthesis of PGE1or released and adjuvant arthritis rats were significantly inhibited. Sensitized before and after administration of Arthus reaction without significant effect; but in the attack before and after the administration had obvious inhibition, attack and passive Arthus response inhibition rate of 5h were 14.1% and32.8%.
4: antioxidant effects of essential oil of Abies NEPHROLEPIS Maxim can be significantly reduced in mouse liver lipid peroxides malondialdehyde content, improve the mouse liver tissue in rat serum catalase and superoxide dismutase activity in.
5: the essential oil of Abies NEPHROLEPIS Maxim toxicity to mice LD50is 8.4965 +1.5419ml / kg, after intragastric administration, MICE activities significantly reduced, breathing slow and deep, finally died due to respiratory suppression depth.
