Stilbenes, also known as astragalosides, are polyhydrostilbenes, which are widely found in mosses and higher plants. It has been identified as a plant antitoxin, which is produced by plants under adverse conditions such as fungal infection, UV irradiation and mechanical damage. It has been found that stilbene glycosides have various physiological activities and medicinal values, and have shown functionalities in hypolipidemic, anti-aging, and inhibition, which highlight their important research and development value in today's increasingly aging society.
The unique components of Chinese medicine He Shou Wu are stilbene glycosides.

Stilbene glycosides have cerebral protection, free radical scavenging, hypolipidemic, hepatoprotective, antitumor, vasodilatory, and atherosclerosis inhibiting effects.
It is used for content determination/identification/pharmacological experiments, etc.
Pharmacological efficacy:It has biological activities such as regulating blood lipids, antioxidant, improving learning and memory ability, protecting nerve cells, protecting vascular epithelial cells, etc.
Ecdoin is also called tetrahydromethylpyrimidine carboxylic acid. Ecdysone protects halophilic bacteria from damage and it has two major functions: 1) Moisturizing: It is an important substance to maintain the osmotic pressure balance and its unique molecular structure has strong water Chemicalbook complexation ability, which can structure free water in cells and is a very excellent natural moisturizer. 2) Repairing: Ecdysone can counteract UV damage to skin and repair UV-induced cell DNA damage.
Ektol is widely used in skin care products for its moisturizing and repairing properties, and can be used to improve skin tone.
