Here we report a previously unrecorded species of Korean Allium (Alliaceae) from Geomundo, Yeosu-si, Jeollanam-do. This taxon, A. pseudojaponicum Makino which has been known to distribute only in the southern part of Japan up to date, is easily distinguished from A. thunbergii G. don by lustrous evergreen leaves and lateral scapes as well as chromosome number (2n=32). The common name, 'Gaet-bu-chu', was newly given considering the property of habitat, which is the dry and rocky grasslands facing to the sea in Korea and Japan. In this study, we redescribe morphological characters, and provide illustrations of habit as well as photographs of habitat.

Angiotensin converting enzyme(ACE) belongs to the class of zinc protease and plays an important role in the regulation of blood pressure. In this experiment, we investigated the inhibitory activities of medicinal plant extracts on ACE. Fifty medicinal plants were selected and the extracts were prepared by refluxing with 70% methanol. Among the extracts, eleven medicinal plant extracts such as Sedum sarmentosum Bunge, Petasites japonicus(s.et z.) Max, Rubus coreanus, Morus bombycis Koidz, Acorus calamus var. angustatus, Glycyrhiza glabra, Equisetum hyemale, Portulaca oleracea L., Prunella vulgaris var. lilacina Nakai, Sorbus commixta Hedl, Allium thunbergii showed more than 50% inhibitory activities, and Paeonia suffruticosa Andr., lnula helenium, Acanthopanax senticosus Harms, Dendrobium moniliforme, Juglans mandshurica, Zizyphus jujuba, Leonurus artemisia, Aster scaber Thunb, Vitex rotundifolia, Platycodon grandiflorum, Prunus persica, Ligularia fischeri showed $40{\sim}49%$ inhibitory activities. Therefore these extracts which contain high ACE inhibitory activities may be useful as antihypertension agents and to the treatment of hypertension.
