Plantago asiatica, is a plant of genus Plantago, Herbs, perennial. Roots numerous, fibrous. Leaves basal; petiole 2-15(-27) cm, sparsely pubescent; leaf blade broadly ovate to broadly elliptic, 4-12 × 2.5-6.5 cm, thinly papery to papery, sparsely pubescent, veins 3-7, base broadly cuneate to subrounded and decurrent onto petiole, margin entire, repand, serrate, or dentate, apex obtuse to acute. UV-absorbing compounds such as flavonoids and phenolic acids are important for plants to protect their vegetative organs from harmful UV radiation at higher altitude. Two chemotypes, i.e., acteoside mainly-containing (AM) type and plantamajoside mainly-containing (PM) type were found by qualitative HPLC analysis of the phenolics in the leaves of Plantagoasiatica in Mt. The seeds of Plantagoasiatica L. were often used as a traditional Chinese medicine for some immunologically weak patients suffering from chronic illness. These uses could be related to immunomodulatory properties of the plant.
