Korean folk medicine 'Jil-Kyung-Ee' has been used to cure female disease, acute gastritis, edema, abdominal pain and pleurisy. The botanical origin of the crude drug has not been confirmed pharmocognostically. To clarify the botanical origin of 'Jil-Kyung-Ee', the morphological and anatomical characteristics of the leaves and roots of Plantago species growing in Korea, i.e. P. asiatica L., P. camtschatica Cham., P. depressa Willd., P. lanceolata L., P. major L. var. japonica (Fr. et Sav.) Miyabe were compared. As a result, it was determined that 'Jil-Kyung-Ee' was the whole plant body of Plantago asiatica and Plantago camtschatica.

Coastal plant species, Plantago camtschatica Cham. native to the coastal region of the East Sea were sampled and then morphologically different 20 endophytic fungal strains were purely isolated. Phylogenetic analysis of isolates was done by the Bayesian program based on sequenced internal transcribed spacer (ITS-rDNA) region. Culture filtrates of each of 20 isolates were treated to Waito-c rice (WR) seedlings for verifying plant growth-promoting activity, respectively. As the results, E/PC/10/1 strain showed the highest plant growth-promoting activity among them. The culture filtrate of the strain E/PC/10/1 was revealed as containing gibberellins ($GA_1$, $GA_3$, $GA_4$) by using HPLC, and gas GC/MS with selected ion monitoring (SIM). Finally, this strain was identified as novel Penicillium spinulosum species that producing new GAs with microscopic observation and further molecular analysis with beta-tubulin gene sequence.
