According to traditional Chinese medicine, lotus leaves are bitter and astringent in nature, neutral in nature, and belong to the liver, spleen, stomach and heart meridians. They have the effects of clearing summer heat and promoting diuresis, ascending clear Yang, cooling blood and stopping bleeding. Lotus leaf alkaloids, as one of the main components in lotus leaves, also have certain applications in traditional medicine, such as potentially helping to clear heat and relieve summer heat. However, there is currently insufficient modern medical evidence to support the specific mechanisms and effects of these functions.
Modern pharmacological research applications:
Lipid-lowering effect: Pharmacological studies have shown that lotus leaves have the effect of lowering lipids and removing oil. Lotus leaf alkaloid may be one of the important components that play a role in regulating blood lipids, but it cannot be equated alone with lotus leaf products that have the health care effect of regulating blood lipids. Regulating blood lipids is a complex process and is influenced by multiple factors.
Biological activity study: Nuciferine is an antagonist of 5-HT2A, 5-HT2C and 5-HT2B, with IC50 values of 478 nM, 131 nM and 1μM respectively; It is also a reverse agonist of 5-HT7, with an IC50 of 150 nM. It is also an agonist or antagonist of the 5-HT6 receptor (EC50 is 700 nM), the 5-HT1A receptor (EC50 is 3.2 μM), the D2 receptor (EC50 is 64 nM), the D4 receptor (EC50 is 2 μM), and the D5 receptor (EC50 is 2.6 μM). In vitro studies have shown that it is also an effective inhibitor of peristalsis in adult schistosomes, capable of effectively suppressing the basal and 5-HT-induced movements of adult schistosomes. The inhibitory concentrations of Schistosomule on schistosomes are 0.24±0.04 μM and 0.62±0.22 μM, respectively.
