1.What is Salsa seed extract?
Horse Chestnut Extract powder is the brownish-yellow color extracted from the dry mature seeds of Aesculus chinensis Bge., Aesculus chinensis Bge. var. chekiangensis (Hu et Fang) Fang or Aesculus wilsonii Rehd. Powdery substance, the main active ingredient is aescin, which has anti-inflammatory, anti-exudation, anti-brain edema, and anti-tumor effects.


Sala fruit extract has anti-tissue edema, reduces vascular permeability and prevents water accumulation in tissues, and quickly eliminates the heavy feeling and pressure caused by local edema. It can treat stomach cold pain, abdominal fullness, malaria, and dysentery. It has significant effects on anti-inflammation, anti-exudation, and detumescence. It can restore the normal permeability of capillaries, increase venous tension, and improve microcirculation. In Europe, its indications are mainly edema caused by peripheral circulation disorders, mainly in oral and external dosage forms. Aescin is an important natural medicine recognized internationally. After long-term clinical observation of thousands of cases, it is believed that sodium fascinate has high therapeutic value for trauma and peripheral vascular diseases.

1.2 Chemical composition
(1). Saponins
Aescin is a mixture of more than 30 saponins extracted from the seeds of Sala, and belongs to pentacyclic triterpene saponins. The main forms are α-aescin and β-aescin.
Hydrolyze aescin with alkali to obtain aescin, acetic acid, tiglic acid, glucuronic acid, and glucose of equal molecular weight. Aescin can be hydrolyzed under strong hydrolysis conditions to obtain equal molecular weight aescin, α-methyl-β-hydroxybutyric acid, acetic acid, glucose, xylose, and glucuronic acid.

4.Benefits and Application
Health Benefits
According to the latest pharmacological experiments, Horse Chestnut Extract powder has the following effects on health:
Anti-inflammatory and antibacterial effect
Sodium aescinate has obvious inhibitory effect on pulmonary inflammation caused by epinephrine and endotoxin; purified aescinate has no antibacterial effect on Escherichia coli; it has strong antibacterial effect on Staphylococcus aureus The intensity of action increases with increasing drug concentration.
Cholesterol-lowering effect
Antioxidant free radical effect
Oxygen free radicals have strong oxidative properties and can oxidize intracellular substances, especially unsaturated fatty acids. The human brain contains a large amount of unsaturated fatty acids, which are extremely sensitive to oxidative damage. Studies have shown that a large number of oxygen free radicals lead to cerebral ischemia-reperfusion injury, and sodium aescinate can improve the nerve cell damage caused by oxygen free radicals.
Increasing venous tone
Sodium aescinate has a very good therapeutic effect on varicose veins, venous thrombosis, chronic lower extremity, venous insufficiency, and lower extremity arterial obstructive diseases.
Anti-osmotic detumescence effect
β-Aescinate sodium has obvious anti-exudation and anti-edema effect on cerebral edema after cerebral hemorrhage; it can promote hematoma absorption, reduce cerebral edema, and improve neurological function in a short period of time in the treatment of cerebral hemorrhage.
Protection against ischemic injury
Protective effect on the gastrointestinal tract
Sala seed extract has anti-gastric ulcer effect caused by aspirin, and this effect is closely related to the administration time.
Antitumor effect
Aescin-Ia can be transformed by human intestinal bacteria and Lactobacillus brevis crude enzymes to produce deacyl aescin I, which has anti-tumor activity.
Application
✔️Used in the field of medicine,Salo fruit extract can treat stomach cold, pain, abdominal fullness, malaria, dysentery.
5.Extraction process
The extraction methods in the laboratory include accelerated solvent extraction, reflux extraction, alcohol extraction and ultrasonic extraction. The optimal conditions for the accelerated solvent extraction method to extract aescin from the seeds of aescin, that is, the extraction solvent is 70% methanol, the extraction temperature is 100 ℃, the static extraction time is 7 min, the extraction frequency is 1 time, and the extraction rate of aescin is excellent. in reflux extraction and ultrasonic extraction. The optimal extraction process for alcohol extraction of aescin is 95% ethanol as the extract solution, extraction temperature is 70 e, extraction time is 3 h, ratio of extraction solution volume to sample mass is 8:1, and extraction times are three times . The yield was 1.46% aescin.
