1. Isocorynoxeine (7-Isocorynoxeine) shows the effects of lowering blood pressure, vasodilatation, and protection against ischemia-induced neuronal damage. 2. Isocorynoxeine exhibits a significant neuroprotective effect against glutamate-induced HT22 cell death at the maximum concentration.

Taurine (2-Aminoethanesulfonic acid), an organic acid, is distributed in various animal tissues.

Pingpeimine A has the effect of expectorating and lowering blood pressure. Derived from Fritillaria sibiricum.

Isosteviol ((-)-Isosteviol), a common natural sweetener, belongs to tetracyclic diterpene glycosides. The pharmacology researches have suggested that stevioside and its hydrolysis products, steviol, isosteviol and steviolbioside, have many biological activities, such as reducing blood glucose, lowering blood pressure, anti-inflammation, anti-tumor, anti-diarrhea, antibacterium, immunoregulation, etc.

Veratric acid (3,4-Dimethoxybenzoic acid) is a simple benzoic acid derived from plants and fruits with anti-oxidant, anti-inflammation and blood pressure-lowering effects.
