The main components of clove extract are eugenol, acetyl eugenol, caryophyllene, vanillin and esters. It is a light yellow to brown liquid that gradually turns black and thickens in the air. It has a clove scent, is insoluble in water and hot water, and is easily soluble in ethanol, hydrous ethanol, ether, oils, propylene glycol and glacial acetic acid. It is stable to heat and can be used in combination with chelating agents to enhance antioxidant capacity. It is useful when used in conjunction with vitamin ChemicalbookE, etc. Multiplying the effect, it will change color and precipitate when encountering metal ions.
Stomach-tonifying effect: Clove is an aromatic stomach-tonifying medicine that can relieve abdominal bloating, enhance digestion, and reduce nausea and vomiting. According to research, clove extract can stimulate the secretion of gastric acid and pepsin, and increase the activity of gastric acid and pepsin, so it can promote digestion and help eliminate stomach cold syndrome such as cold pain in the epigastrium and indigestion. Its function of stimulating gastric juice secretion can It was inhibited by intravenous injection of atropine. It is speculated that the effect of clove on stimulating gastric juice secretion seems to be related to the involvement of cholinergic nerves. 5% eugenol emulsion can also significantly increase gastric mucus secretion without increasing acidity. Clove oil has a slightly less effective effect. Continuous application can deplete the mucus and secrete only non-mucus exudate.
The anti-ulcer effect has been studied on animals. The anti-ulcer effect of clove water extract and ether extract on four gastric ulcer models was studied. The results showed that in addition to having no effect on pyloric ligation ulcer, it also had no effect on water immersion stress. Ulcer models such as ulcers, ulcers induced by indomethacin plus ethanol, and gastric mucosal damage caused by hydrochloric acid all have good protective effects.
