Pharmacological effects Deworming Arecoline is an effective insect repellent ingredient. It has a strong cockroach effect on pork aphids, which causes all insects to paralyze, but it can only make the head and immature sections completely paralyzed by beef aphids, but has little effect on the mid- and post-progesterone segments. In vitro tests also have a paralytic effect on murine worms. Arecoline also poisons aphids but not hookworms. The decoction of betel nut mixed with realgar, cinnamon, and ferulae was fed to mice, which had certain preventive effect on the infection of schistosomiasis, but was not effective in treating schistosomiasis in mice together with alfalfa root, Coptis chinensis, and broad wood. Antifungal, viral effects Aqueous extracts have different degrees of inhibition on dermatophytes such as Trichophyton mentagrophytes in vitro. Decoction and water infusion have a certain inhibitory effect on certain strains of influenza virus type A, and the antiviral effect may be related to the tannins contained therein. Effect on choline receptors The effect of arecoline is similar to that of pilocarpine. Excitable M-cholinergic receptors increase secretion of glands, especially saliva secretion. When the eye drops, the pupils can be reduced. In addition, it can increase bowel movements, contract the bronchus, and slow down the heart rate. Can cause blood vessels to dilate, blood pressure drop, rabbits cause coronary artery contraction after application. 1% solution for glaucoma can reduce intraocular pressure, but the effect lasts for a short time, and it has obvious irritation to the cornea. As a result of the increase in peristalsis, the worms that are paralyzed are excreted. Can also excited N-choline receptors, expressed as skeletal muscle, ganglion, and carotid body. There is also a cholinergic effect on the central nervous system. Intravenous injection of a small amount of arecoline in cats can cause a cortical arousal response, and atropine can reduce or block this effect. Other effects The subcutaneous injection of arecoline in mice inhibited their general activities, and the reduction in activity caused by chlorpromazine and memory impairment were improved. It has been proven that betel nut contains carcinogenicity to humans. People who chewed betel nuts usually have diminished taste, increased appetite, easily shaken teeth, less diarrhea, and less sore throat and can manage abdominal pain. This may be due to the large amount of tannins contained therein. In addition, betel nut diets have fewer intestinal parasites and less thirst, which may be related to the effects of arecoline. Experiments have also shown that betel nut has certain toxicity to mouse embryos, which can delay the development of the fetus, especially the unprocessed betel nut. Continuous use of betel nut can enhance the carcinogenic effects of carcinogenic substances 4-nitroquinoline-1-oxide and mercaptoacetamide in rats.
