Identification
Biological Activities
Compounds
Lactuca raddeana var. raddeana serves as a significant botanical source for the chemical compound known as lactuside B. Recent research highlights that this specific component plays a crucial role in protecting the brain during ischemia-reperfusion injury. In experimental models, lactuside B has been shown to effectively reduce brain infarct volumes in the cerebral cortex. The compound achieves this neuroprotective effect by upregulating bcl-2 expression while simultaneously downregulating bax expression at both the mRNA and protein levels. These findings suggest that the compounds derived from this plant offer therapeutic potential that may even outperform certain standard medical controls.
Conditions
Lactuca raddeana var. raddeana, specifically through its major chemical component lactuside B, demonstrates a therapeutic effect against cerebral ischemia-reperfusion injury. Research utilizing rat models shows that this plant extract effectively reduces brain infarct volumes in the cerebral cortex. The mechanism involves the upregulation of bcl-2 mRNA and protein expression alongside the downregulation of bax mRNA and protein. By increasing the ratio of bcl-2 to bax, the treatment promotes neuroprotection against ischemic damage. These findings suggest that lactuside B performs even more effectively than the positive control medicine, nimodipine, in resisting cerebral ischemia.
Preparations
Parts used
Lactuca raddeana var. raddeana contains a specific part known as the rhizome, which serves as a critical source for medicinal compounds. Within this structure, researchers have identified the major chemical component lactuside B, which shows significant therapeutic potential. Recent studies indicate that this substance can effectively reduce brain infarct volumes in rats following cerebral ischemia-reperfusion injury. By modulating the expression of bcl-2 and bax mRNA and proteins, lactuside B helps protect the cerebral cortex from damage. Ultimately, the findings suggest that this rhizome-derived compound plays a vital role in resisting the harmful effects of cerebral ischemia.
