In vitro antibacterial experiments have confirmed that the Paulownia tomentosa extract has a stronger effect on Staphylococcus aureus and Bacillus subtilis, followed by Carlsbergensis yeast, and weaker effect on Escherichia coli. The butanol extract of Paulownia tomentosa stem has antibacterial effect on Staphylococcus aureus, Streptococcus pyogenes infection and Streptococcus-like infection. Its key component is Bauhinia glycoside I, and the minimum antibacterial concentration value (MIC) for the above bacteria is 150 μg/ml. Several types of crystals separated from Paulownia tomentosa leaves have a certain inhibitory effect on 8 common bacteria, cold virus and Sendai virus. The dsesamin contained in the wood of Paulownia tomentosa has an inhibitory effect on cold viruses, Sendai viruses and tuberculosis bacteria. The minimum antibacterial concentrations of ursolic acid contained in Paulownia tomentosa leaves against Gram-positive bacteria, Gram-negative bacteria and yeast outside the body are 50-400μg/ml, 200-800μg/ml and 100-700μg/ml respectively. Paulownia flower extract also has a strong antibacterial effect.

2. Antitussive, expectorant and antiasthmatic effects: The extracts of Paulownia fruit and Paulownia wood residue can significantly increase the duration of sulfur dioxide-induced coughing in mice, and can significantly increase the tipping time of guinea pigs caused by nitrosamine sprayers, indicating that they have antiasthmatic effects. The extract of Paulownia leaves foamed plastic can significantly increase the excretion of phenol red in the respiratory system of mice, indicating that it has the effect of reducing phlegm.

3. Effects on the central nervous system: It has significant stabilizing and cooling effects, can reduce the normal body temperature of rats, reduce the spontaneous activities of mice, and can enhance the hypnotic effect of pentobarbital and the anticonvulsant effect of pentylenetetrazol.

4. Anti-cancer effect: It has a significant inhibitory effect on the formation of liver cancer cells outside the body, and can prolong the life of mice with ascites cancer in the Rabbit model.

5. Improve the efficacy of insecticides: Paulownia tomentosa contains paulowniain and sesamin, which can improve the efficacy of pyrethrins and allyl pyrethrins in killing insects (flies, mosquitoes, etc.).

6. Other effects: Paulownia fruit has the effect of lowering blood pressure, and its effect on lowering blood pressure in patients with hypertension is more significant. It also has anti-infection effects, can increase liver glycogen, reduce cardiac and striated muscle glycogen, and has hormone-like effects. Clinical experiments show that 100 mg/kg has the effect of reducing blood cell transaminase. The phloem of the petiole of Paulownia tomentosa contains catalpol, and experiments have shown that catalpol has the effects of promoting urination and laxative. The bark of Paulownia tomentosa contains syringin. Experiments have shown that syringin has a significant effect of activating blood circulation. It can be used to activate blood circulation during surgery and significantly reduce bleeding.
