A quantitative method using ultra performance liquid chromatography with a photodiode array detector (UPLCPDA) was established for the analysis of 2 major plant metabolites: ${\beta}$-asarone and ${\alpha}$-asarone from Acorus gramineus, A. tatarinowii, A. calamus and Anemone altaica, and their contents are compared with other herbs of Acorus species. The method was validated according to the International Conference on harmonization (ICH) guideline for validation of analytical procedures with respect to precision, accuracy, and linearity. The average content of ${\beta}$-asarone in Acorus gramineus was significantly higher than that in others, with the second highest concentration observed in A. tatarinowii, and only a trace amounts found in A. calamus and Anemone altaica. In contrast, the average content of ${\alpha}$-asarone in A. calamus was the highest, followed by that in Acorus gramineus and A. tatarinowii. principle component analysis (PCA) confirmed that ${\beta}$-asarone and ${\alpha}$-asarone content differed among the species. These results suggest that this UPLC-PDA method can be considered as good quality control criteria for Acorus gramineus.

The Korean plant names Changpo and Sukchangpo, including their related names Suchangpo and Kyeson, were somewhat confusingly used in both the Korean classics and even now. To clarify these names, the names written in the Chinese classics and the Korean classics were examined closely and compared to those of the modern flora of China and Korea. In the Chinese classics, Changpo and Sukchangpo were considered as conspecific with Acorus calamus, which has leaves with distinct veins, whereas Sukchangpo and Kyeson have leaves without distinct veins and are considered as A. gramineus. However, in the Korean classics, these names have been confusingly used thus far. Sukchangpo and Gyeson were considered as A. gramineus, and Sukchangpo and Changpo were considered as A. calamus, erroneously. Therefore, the following corrections are needed: plants having distinct leaf veins were named Changpo (A. calamus), and plants having vague leaf veins were named Sukchangpo (A. gramineus), and the names of Sukchangpo and Kyeson should be discarded to avoid confusion. In addition, to respond to the Convention on Biological Diversity, we propose a study to clarify the taxonomic identities of the plant names written in Chinese script and an examination of the Korean plant names listed in the Korean classics.

This study was conducted to find out the cadmium (Cd) accumulation and tolerance of Iris pseudacorus and Acorus calamus as aquatic plants native to Korea for Cd removal in water. In the range of Cd concentration from $10{\mu}M$ to $130{\mu}M$, the Cd lethal dose 50 ($LD_{50}$) was $78.5{\mu}M$ in I. pseudacorus and $47.6{\mu}M$ in A. calamus. In I. pseudacorus, superoxide dismutase and peroxidase as antioxidants were relatively effective against oxidative stress caused by Cd, while catalase, superoxide dismutase, and polyphenolics were effective in A. calamus. The polyphenolics known as typical antioxidants were not detected in I. pseudacorus. In both species, the Cd accumulation in plants increased with the higher Cd concentration and the longer processing period. Also, the absorbed Cd was accumulated mainly in the roots. The amount of Cd accumulated in the shoot part was maximally $548.1mg{\cdot}kg^{-1}$ (82.1% to Cd accumulated in the root part) in I. pseudacorus and $121.4mg{\cdot}kg^{-1}$ (13.7%) in A. calamus, which implied that both species all were enough evaluated as Cd hyper-accumulators based on 0.01% or more Cd accumulation in the shoot. Especially I. pseudacorus showed outstanding ability to move well Cd into the shoots from the roots and high tolerance to Cd stress.

BACKGROUND: Acorus gramineus is of medicinal plants that exhibit variable biological activities for human health and against insect pests. The extracts of A. gramineus was examined in an attempt to develop a natural repellent against human disease-mediating Culex pipiens. METHODS AND RESULTS: The roots of A. gramineus dried under dark conditions were homogenized and extracted with ethanol. The extracts were subjected to repellent activity assays against C. pipiens in a hand-made acrylamide box with three accessible rooms. Significantly low number of mosquitos was found in the room previously fumigated with the extracts at 50 mg/L on the filter paper, exhibiting less than 20% of mosquitos tested. More than 50% of mosquitos tested was found in the room without the extracts, but less than 30% was found in the room that released mosquitos. GC/MS analysis detected ${\beta}$-asarone as a main component of the extracts. The commercial asarones (${\alpha}$ and ${\beta}$) showed a repellent activity at 50 mg/L on the filter paper similar to the extracts. CONCLUSION(S): A. gramineus has potential for use as a mosquito repellent since ${\beta}$-asarone, a main component of the plant, exhibited a strong repellent activity against C. pipiens.

To investigate the potential of treatment, antimicrobial activity of various oriental herb extracts were tested for Gardnerella vaginalis, which is the predominant organism in bacterial vaginosis. Among the tested 14 oriental herbs, water-extracts of Kalkeun, Kosam, Nuro, Pakjakyak, Sukchangpo, Shiyup, Junghyang and Hwangryun represented antibacterial activities against G. vaginalis. The minimal inhibition concentration (MIC) of Shiyup against G. vaginais was 0.63 mg/mL, and those of Pakjakyak and Hwangryun, Kalkeun and Nuro, Kosam, Sukchangpo and Junghyang were 1.25 mg/mL, 2.5 mg/mL, and 5 mg/mL, respectively. There-fore, the water-extracts of Kalkeun, Kosam, Nuro, Pakjakyak, Sukchangpo, Shiyup, Junghyang and Hwangryun were considered to be potential treatment of bacterial vaginosis caused by G. vaginalis.

This study has been carried out to investigate the chemical composition of Acorus calamus L., a wild plant (Chang Po) which has long been used as a medicine or a hair rinse in Korea and China. Potassium was found to be the most predominant mineral in leaf and root, followed by calcium, magnesium, and phosphorus, in a decreasing order. Contents of potassium in leaf and root account for 54a.65 mg% and 242.87 mg%, respectively. Contents of these minerals in leaf were higher value than that in root. Glucose and fructose were found to be the major free sugars in leaf and root. Malic acid was the most abundant organic acid of leaf and root, and followed by citric acid. Fourteen different kinds of fatty acids were identified from the leaf and root. Content of unsaturated fatty acids. such as linolenic, and linoleic acid ware higher than that of saturated fatty acids. Content of total amino acids was 3 times higher in leaf than that in root. Leucine was the major amino acid in leaf and glutamic acid in root.
