Synopsis：Progesterone (also known as progesterone, geststerone, luteosterol, progesterone, progesterone, progesterone, progesterone, progesterone, progesterone, lutein or progesterone, abbreviated as P4, also known as (gesterol-4-ene-3,20-dione), is an endogenous steroid and progesterone sex hormone, and also the main pregnancy hormone in the body, secreted by the female ovary. Progesterone is a steroid hormone with 21 carbon atoms secreted by ovarian luteal cells, and is also the intermediate product of all steroids, which belongs to progesterone. There are two types of crystal, namely α- Type and β- The two types have the same physiological activity of , α- The type is precipitated from dilute ethanol and is a white prism crystal of orthorhombic system, β- The results showed that the crystal was of the orthogonal crystal system, which was white needle crystal, neither of them was soluble in water, and was soluble in ethanol, ether, chloroform, acetone, dioxane and sulfuric acid.
