Stigmasterol is one of a group of phytosterol. Stigmasterol is an unsaturated plant sterol occuring in plant fats or oils of soybean,calabar bean and rape seed,and in a number of medicinal herbs. Research has indicated that stigmasterol mar be useful in prevention of certain cancers, including ovarian, prostate, breast and colon cancers. Studies have also indicated that a diet high in phytosterols may inhibit the absorption of cholesterol and lower serum cholesterol levels by compting for intestinal absorption.

Function&Application

DL-2-Aminobutyric acid is widely used in fields of medicine, food processing, industry, etc.

Minoxidil was the first drug approved by the FDA for the treatment of androgenetic alopecia (hair loss). Before that, minoxidil had been used as vasodilator drug prescribed as oral tablet to treat high blood pressure, with side effects that included hair growth and reversal of male baldness.Since the 1990s, numerous generic forms of minoxidil have become available to treat hair loss while the oral form is still used to treat high blood pressure.

Minoxidil is a vasodilator medication known for its ability to slow or stop hair loss and promote hair regrowth. It is available over the counter for treatment of androgenic alopecia, among other baldness treatments, but measurable changes disappear within months after discontinuation of treatment. Its effectiveness has largely been demonstrated in younger men (18 to 41 years of age), the younger the better.

Minoxidil is a potassium channel agonist. It contains the chemical structure of nitric oxide), a blood vessel dilator, and may be a nitric oxide agonist. This appears to explain its vasodilatory effects, but may also be linked to minoxidil’s ability to stimulate hair growth and treat hair loss. Since minoxidil is a nitric oxide-related compound, it was suspected to act via activation of guanylate cyclase, an enzyme involved in vasodilation.
