  • We evaluated the actual distribution, present status, and number of remnant individuals of Korean Sagittaria aginashi (Alismataceae) based on herbarium specimens and field surveys. We also reidentified Korean S. aginashi by analyzing sequences of the internal transcribed spacer (ITS) region. We found nine specimens of S. aginashi in herbaria from four localities housed at the Osaka Museum of Natural History (OSA) and at the Korea National Herbarium (KH). During our field research, we could not confirm the current statuses of two collection localities (Taereung and Ansan-si), though this was not the case for Ulsan-si. In addition, we found two new localities in Ulsan-si and Yangsan-si. These three remnant populations are distributed in wetlands in mountainous areas (elev. 480-740 m). With regard to the number of flowering and immature individuals in the three localities, there were <50 and <2,000, respectively, in total. ITS sequences demonstrated that the sequences of Korean and Japanese S. aginashi are uniform and distinct from other Sagittaria species. These results indicate that S. aginashi is a rare and threatened species in Korea. It should be listed as an endangered species on the Korean Red List and requires urgent protection by conservation programs, including the extensive surveys of other possible natural habitats.

  • Alisol B(II) and alisol B monoacetate (III) isolated from the rhizome of Alisma orientale Jazepczuk (Alismataceae) showed antagonistic effects against the contractions induced by angiotensin and bradykinin in rat ileum. However, they seem to be nonspecific antagonism.

  • Alismatis Rhizoma is originated from the rhizome of Alisma plantago-aquatica L. var. orientale Samuelson or A. canaliculatum A. Br. et Bouche (Alismataceae). Prostane-type triterpenes, guaiane-type sesquiterpenes, and kaurane-type diterpenes have been reported as the main canstituents from these plants. Four prostane-type triterpenes. alisol B 23-acetate (1). alisol C 23-acetate (2), alisol B (3). and alisol A 24-actate (4). were isolated from the EtOAc-soluble fraction of this dried rhizome.

  • In order to clarify the originality of several Alisma Rhizomes, we investigated the differences of their morphological, anatomical and physiochemical characteristics. Morphological observation shows the variability of Alisma shape and quality. The diversities in morphological shapes and qualities of tuber were observed among different origins. Chinese product looked like corm shape, but korean's irregular shape. The microscopic observation of korean Alisma revealed the presence of irregular vascular bundle which was scattered transversely and longitudinaly, which was different from that of the rhizome. This facts suggest that the portion of crude drug in Alisma should be the corm rather than the rhizome. In the physicochemical differences, chinese Alisma contains larger amount of mineral elements such as K, Na and Ca than korean Alisma. On the contrary, protein contents in lyophilized powder of aqueous extracts in korean Alisma rhizome was significantly higher than chinese Alisma rhizome. The leaves and stems contained larger amount of Ca and Na than tuber, and may be used as the osmotic diuretics for chinese traditional medicine.

  • Echinodorus cordifolius (L.) is an aquatic plant in the family Alismataceae. The anti-skin aging activity of E. cordifolius (L.) has not been yet reported. Therefore, the objective of the present study was to prepare 70% ethanol extract (ECEE) from E. cordifolius (L.) and investigate their antioxidant and anti-hyaluronidase activities for confirm the potential of anti-skin aging. ECEE showed good activities of DPPH, hydrogen peroxide scavenging, and hyaluronidase inhibition, with EC50 and IC50 values of 31.4, 300, and 450 ㎍/mL, respectively. ECEE also significantly improved cell viability and inhibited intracellular reactive oxygen species dose-dependently against 1 mM hydrogen peroxide-induced oxidative stress in immortalized human keratinocytes (HaCaT cells). Furthermore, ECEE upregulated hyaluronic acid (HA)-synthesizing enzyme hyaluronan synthase 2 (HAS2) expression level, but downregulated expression level of HA-degrading enzyme hyaluronidase 2, resulting in increased HA production in HaCaT cells. Taken together, these results suggest that ECEE shows antioxidant and anti-hyaluronidase potential and could be a functional cosmetic ingredients for anti-skin aging.

  • The rhizome of Alisma orientale Juzep (Alismataceae) has been used as a crude drug for diabetes, edema, inflammation and urinary disturbances in oriental medicine. Recent animal studies have shown that the extract of Alisma orientale rhizome (AOR) can potently lower high levels of serum lipids and improve insulin resistance, which are usually detected in patients and animals with non-alcoholic fatty liver disease. So, we studied the antioxidative effects of AOR extracts and fraction in vitro and their protective effects against acute hepatotoxicity induced by $CCl_4$ in vivo.. We then investigated the effects of each fraction on hepatotoxicity induced by tert-butyl hydroperoxide (t-BHP). DAOR (dichloromethane fraction of the Alisma orientale rhizome) scavenged free radicals and superoxide anions. DAOR protected against $CCl_4$ induced hepatotoxicity. DAOR had hepatoprotective and antioxidative effects against t-BHP-induced hepatotoxicity in HepG2 cells and in rats.

  • Four protostane-type triterpenes, alisol B 23-acetate (1a), alisol C 23-acetate (2a), alisol B(3a), and alisol A 24-acetate (4a), were isolated from the rhizome of Alismatis plantago-aquatica L. var. orientale Samuelson (Alismataceae) and eleven protostane derivatives (compounds 1-11) were obtained by selective modification from alisol B 23-acetate (1a). These compounds were investigated for their anti-complement activity against the classical pathway of the complement system. Alisol B (3a) and alisol A 24-acetate (4a) exhibited anti-complement activity with $IC_{50} values of 150 and 130 \mu$ M. Among the synthetic derivatives, the tetrahydroxylated protostane triterpene (9) showed moderate inhibitory activity with $IC_{50} value of 97.1 \mu$ M. Introduction of an aldehyde group at C-23 (10; $IC_{50} value, 47.7 \mu$ M) showed the most potent inhibitory effect on the complement system in vitro.

  • We conducted a taxonomic study and agricultural environmental risk assessments of 41 putative invasive alien plants designated by the Ministry of Environment in 2016. In order to achieve the goal, we carried out the field survey four times including the United States, Australia, and Mexico, and investigated specimens, literature, and other information including seed morphology, classification key, and habitat conditions. In this study, we reported the taxonomic characters, ecological risk, and weed risk assessment of 41 putative invasive alien plants, and suggested significant information about 11 species to contribute to establish solutions of regulation management for putative invasive alien plants - Spirodela punctata (G.Mey.)

  • Alismatis Rhizoma is an oriental medicine originated from the rhizome of Alisma orientale or Alisma plangtago-aquatica var. orientale (Alismataceae). As an standard compound of this plant, alisol B 23-acetate was isolated from the dichloromethane fraction of Alisma orientale and identified by the spectroscopic evidences. A Quantitative analysis of alisol B 23-acetate using HPLC method showed that the average content was 0.47$\pm$0.11% in 33 samples throughout the various regions of Korea.
