The efficacy and edible value of lotus seed heart

Speaking of lotus seed heart, I believe many people will feel a sense of bitterness in their hearts. It is the mature seed of water lily, which has the effects of clearing the heart and removing heat, astringing essence, stopping bleeding, and relieving cough. Lotus seed heart has high edible value and medicinal value.

Medicinal value of lotus seed heart

1. Antihypertensive effect. Crystallized lotus seed alkaloids extracted from lotus seed core have a short-term antihypertensive effect. When changed to quaternary ammonium salt, a strong and lasting antihypertensive effect appears. Oxymethyl-liensinine methyl sulfate quaternary ammonium salt has a strong and lasting blocking effect on the vagus ganglion, but it does not cause a lasting antihypertensive effect through the vagus nerve; spinal cat and dog head cross-circulation tests both indicate that its antihypertensive mechanism is mainly peripheral. Non-crystalline alkaloid Nn-9 from lotus seed core has a strong antihypertensive effect. Intravenous injection of 1 to 2 mg/kg in anesthetized cats can reduce the original blood pressure level by about 50% and maintain it for 2 to 3 hours; the blood pressure of dogs recovers in half an hour; and the blood pressure of rabbits does not decrease. It has rapid tolerance. Further experiments have shown that the antihypertensive mechanism of this alkaloid is mainly the release of histamine, which dilates peripheral blood vessels, and is also related to neural factors.

2. Cardiovascular effects: Intravenous injection of 1-2 mg/kg of amorphous alkaloid Nn-9 to anesthetized cats can reduce blood pressure by 50% and maintain for 2-3 hours; the same dose can only last for 30 minutes for dogs; it has no antihypertensive effect on rabbits, and has rapid tolerance to the antihypertensive effect on cats and dogs. The antihypertensive mechanism of Nn-9 is mainly the release of histamine, which causes peripheral vasodilation, and is also related to neural factors. Intravenous injection of 10 mg/kg of lianxin alkaloid to anesthetized cats also has a short-term antihypertensive effect, which recovers in 10-20 minutes; but if it is changed to quaternary ammonium alkaloid, a strong and lasting antihypertensive effect will appear. From the experimental results, crystalline lianxin alkaloid is not the main antihypertensive component, while amorphous alkaloid Nn-9 has a strong antihypertensive effect.

3. Effect on smooth muscle: Demethylcoclamine has a significant smooth muscle relaxant effect.
