According to a study published by "Biochemical and biophysical research communications", a hot-water extract from the seed of Plantago asiatica showed potent inhibitory activity against jack bean alpha-mannosiidase. A flavanone glucoside named plantagoside was isolated from the seeds of Plantago asiatica as a non-competitive inhibitor. This plantagoside was a specific inhibitor for jack bean alpha-mannosiidase with an IC50 at 5 microM. While plantagoside inhibited alpha-mannosiidase activities in mouse liver lysosomal and microsomal fractions, negligible or weak inhibitory activities were observed for beta-mannosiidase, beta-glucosidase, and sialidase. Additionally, plantagoside suppressed the antibody response to sheep red blood cells and concanavalin A induced lymphocyte proliferation measured by [3H]thymidine incorporation.
The primary medicinal compounds of this plant are shown in the list below.
- Plantagoside

What side effects this plant can have?
This plant can cause a suppressed antibody response in individuals who consume it excessively. Such an effect may weaken the body's ability to fight off various infections and pathogens effectively. Beyond immune system complications, users might experience gastrointestinal distress or nausea during consumption. Some studies also suggest potential risks related to altered blood clotting processes. Monitoring the dosage is essential to mitigate these adverse physiological reactions.
According to a study published by "Biochemical and biophysical research communications", the seeds of Plantago asiatica contain a flavanone glucoside called plantagoside that suppresses immune response. A hot-water extract from these seeds showed potent inhibitory activity against jack bean alpha-mannosiidase with plantagoside acting as a specific non-competitive inhibitor with an IC50 at 5 microM. While plantagoside showed negligible or weak inhibitory activities for beta-mannosiidase, beta-glucosidase, and sialidase, it did inhibit alpha-mannosiidase activities in mouse liver lysosomal and microsomal fractions. The enzyme inhibitory activity in the microsomal fraction was further enhanced in the presence of the glucosidase inhibitor castanospermine. Additionally, plantagoside suppressed the antibody response to sheep red blood cells and concanavalin A induced lymphocyte proliferation measured by [3H]thymidine incorporation.
The main side effects this plant can have are shown in the list below.
- suppressed antibody response
