Modern research shows that boat-fruited Sterculia contains pentosan and mucus, which belongs to pectin acid and consists of galacturonic acid, arabinose, galactoacetic acid, calcium and magnesium. It contains the active ingredients of Sterculia sterculia, the volatile oil is about 65438 0%, the linden is about 59.04%, and the astringent is about 65438 0.6%. Using modern science and technology, the fatty acid methyl ester derivatives in boat-fruited Sterculia were studied, and six non-fat components were separated and identified. It can be seen that the extract of boat-fruited Sterculia has a laxative effect on the intestine of rabbits, which can increase the intestinal volume and produce mechanical stimulation, leading to an increase in reflex intestinal peristalsis.
Boat-fruited Sterculia is made into 25% solution, which can significantly reduce blood pressure by intravenous injection, intramuscular injection or oral administration. Intravenous injection of 5 mg of boat-fruited Sterculia has a considerable diuretic effect on anesthetized dogs, among which the extract of boat-fruited Sterculia has the strongest diuretic effect. The extract of boat-fruited Sterculia has analgesic effect, and the effect of boat-fruited Sterculia is the strongest. Boat-fruited Sterculia has anti-inflammatory effect, which is one of the commonly used Chinese medicines widely used in clinic, and is often used for tonsillitis and esophagitis.
Recently, scientists conducted an in vitro animal experiment on the inhibition of calcium oxalate crystallization by the extract of boat-fruited Sterculia, and observed the difference and influence of urolithiasis between patients with urolithiasis and healthy people. The results showed that boat-fruited Sterculia had obvious inhibitory effect on the crystallization of calcium oxalate in vivo and in vitro, and increased the excretion of aminopolysaccharide in patients' urine. Urolithiasis is also a common and frequently-occurring disease in China at present, which will bring new medication methods to patients. Therefore, further research on boat-fruited Sterculia will make it possible to develop better new drugs.
