Wild Yam extrat is reach in diosgenin, so it became the most popular source of natural progesterone Most women experience lack of progesterone, not estrogen. Natural progesterone supplements are used to balance estrogen. Natural progesterone has a structure similar to that of human progesterone and is made form plant fats; One of such fats is diosgenin.
1. Antitussive and antiasthmatic effect
The total saponins extracted from the wild yam Dioscorea have obvious antitussive effect when administered orally or intraperitoneally to mice.
2. Effects on the cardiovascular system
Wild yam preparation (water-alcohol extract, mainly containing total saponins) 1:4000~1:1000 concentration has cardiotonic effect on isolated frog heart. Dioscorea saponins from wild yam mainly have antihypertensive effects after iv anesthetized rabbits, dogs, cats, etc., heart rate slows down, and breathing is excited.
3. Anti-inflammatory and analgesic effect 1 gram of wild yam can significantly inhibit the inflammation of the ear shell in mice caused by xylene, the swelling of the foot and metatarsal joints of rats, reduce the permeability of the abdominal capillaries in mice and inhibit the rat Cotton ball granuloma, and can prolong the pain response time in mice and reduce the number of writhing in mice, which proves that pansandra has obvious anti-inflammatory and analgesic effects.
4. Anticoagulation: Dioscorea saponin can prolong blood coagulation time and prothrombin time, and reduce the prothrombin index.
5. Hypoxia tolerance Wild yam preparation ip in mice and ig in rats can reduce the overall rate of oxygen consumption and increase the ability of hypoxia tolerance.
6. Antitussive, antiasthmatic and expectorant effects The total saponins of wild yam have obvious antitussive effects on mice with ammonia-induced cough, but diosgenin is ineffective. The mouse phenol red method experiment shows that ig wild yam total saponins, water-insoluble saponins, and ip panshanlong decoction have significant expectorant effects. Rat capillaries showed that wild yam preparations have expectorant effects. The guinea pig histamine spray method showed that the wheezing inhibition rates were 70% and 100%, respectively, at doses of 0.15g/kg and 0.25g/kg of ig wild yam preparation.
7. Effects on smooth muscle The water-soluble saponins of wild yam have an excitatory effect on the isolated rabbit uterus at a low concentration (4-30mg/100ml), and an inhibitory effect at a high concentration (150mg/100ml). After flushing the solution, normal contractions can be slowly restored. The isolated intestinal muscle test showed that when the wild yam preparation was at a low concentration (1-7 mg/100ml), some intestinal segments showed increased tension. As the concentration increased, the number of intestinal segments with increased tension gradually decreased. 16mg/100ml), most intestinal segments showed decreased tension. The activity of the intestines in situ in anesthetized dogs is excited, and it increases with the increase of the dose.
8. Other effects Wild yam extract also has certain diuretic and anti-radiation effects.

(1) Take about 2g of powder, add 30ml of water, heat on a water bath for 10min, and filter. Take 2ml of the filtrate and put it in a test tube, shake it for 1min, and generate a large amount of persistent cellular Chemicalbook foam.
(2) Take 2g of powder, add an appropriate amount of 80% ethanol, heat and extract, filter, evaporate the ethanol from the filtrate, let it cool, add a small amount of acetic acid to the residue to dissolve, add a few drops of acetic anhydride and concentrated sulfuric acid, and it should be purple-red.
