本植物叶中蛋白BAP-1，在10μg/ml浓度时对TMV病毒的抑制率为76.7%；本植物根所含阿魏酸，在 0.4-0.6mg/ml时能抑制ADP和胶原诱导的大鼠血小板聚集；用氚标记的5-羟色胺标记血小板，阿魏酸钠1-2mg/ml时，对凝血酶诱导的血小板聚集有明显的抑制作用，并能抑制3H-5-HT从血小板释放。同属植物B.spectabilis提取物有抗微生物作用，其叶中含有抗糖尿病作用的肌醇单甲基酯，在200mg/kg灌胃后12h使大鼠血糖水平降低38.20%。相关论述
The protein BAP-1 in the leaves of this plant exhibits a 76.7% inhibition rate against TMV virus at a concentration of 10μg/ml. The root of this plant contains atropine, which can inhibit ADP and collagen-induced platelet aggregation in rats at a concentration of 0.4-0.6mg/ml. When platelets labeled with tritium-labeled 5-hydroxytryptamine are treated with 1-2mg/ml of atropine sodium, there is a significant inhibitory effect on thrombin-induced platelet aggregation, and it can also inhibit the release of 3H-5-HT from platelets. Extracts from the plant B.spectabilis, belonging to the same genus, have antimicrobial effects. Its leaves contain inositol monomethyl ether with anti-diabetic effects, which, when administered orally at a dose of 200mg/kg, reduces the blood glucose level in rats by 38.20% after 12 hours.

以扦插繁殖为主。栽培技术
Mainly focus on propagation by cuttings. Cultivation techniques.

土壤要求富含腐殖质的肥沃土壤。以扦插为主。从5-8月均可进行，而以5月成活率最高。选用充实的当年生半木质化的枝条作插穗，插后保持较高的湿度和28℃左右的温度，20d即可生根，30d后移出栽种。入冬温度维持在5-15℃。
The soil requires rich humus for fertile soil. Propagation by cuttings is the main method. It can be carried out from May to August, with the highest survival rate in May. Select well-developed semi-woody branches from the current year for cuttings. After insertion, maintain high humidity and a temperature of around 28°C. Roots can be formed in about 20 days, and the cuttings can be transplanted after 30 days. Maintain a temperature of 5-15°C in winter.
