To promote the utilization of wild edible plants, this study examined blanching, drying, and fermentation as methods for enhancing the functionality of Hemerocallis coreana Nakai. Specimens fermented for 24 hours at a fermentation temperature of $50^{\circ}C$, with a relative humidity of 65%, contained the highest amount of organic acid (18,109.82 mg/100 g). For the blanched; specimens, total organic acid content decreased about 30% compared with the freeze-dried specimens. The main organic acid of Hemerocallis coreana Nakai was confirmed as succinic acid. After fermentation, free sugars decreased; in particular, specimens fermented at a relative humidity of 80% showed a 32~75% reduction in free sugar compared with the freeze-dried specimens. In terms of amino acid content, Hemerocallis coreana Nakai was mainly composed of valine, isoleucine, and phenylalanine. In fermented specimens the total amino acid content was highest in a moderately fermented (17 hr) specimen, (1,010.71 mg/100 g fresh wt.), but decreased in the maximally fermented (24 hr) specimen. The longer the fermentation, the higher the decrease in non-essential amino acids content, while the content of more essential amino acids consistently increased. In conclusion, since seasoned Hemerocallis coreana Nakai contains a considerable amount of glutamine and asparagine, it has a fresh sour and sweet taste; thus, it will likely be a highly preferred wild edible plant. Also, with an increase of essential amino acids after fermentation, Hemerocallis coreana Nakai is excellent in terms of nutrition. Thus, it may be possible to utilize fermented Hemerocallis coreana Nakai in the development of diverse products.

Genus Hemerocallis is a herbaceous species and some species among their taxa are very important herbal medicines. We evaluated representative samples of the eight taxa in Korea with inter simple sequence repeats (ISSR) markers to estimate phylogenetic relationships within taxa of this genus. The studied taxa were Hemerocallis fulva L., H. fulva for. kwanso, H. dumortieri Morren, H. coreana Nakai, H. hongdoensis M.G.Chung & S.S.Kang, H. middendorffi Trautv. et Mayer, H. thunbergii Baker, H. minor Miller. In addition, we investigated the genetic variation and structure of Korean populations of these taxa. The mean genetic diversity was 0.098 across species, varying from 0.068 to 0.123. A low level of genetic variation was found in populations of Hemerocallis species. Specially, gene diversity for H. minor was maintained the highest among genus Hemerocallis. An indirect estimate of the number of migrants per generation (Nm=0.218) indicated that gene flow was not extensive among Korean populations of Hemerocallis species. The phylogenic tree showed distinct three clades. One includes H. fulva, H. fulva for. kwanso and H. middendorffi. Another includes three Hemerocallis species, H. dumortieri, H. thunbergii and H. minor. The H. coreana and H. hongdoensis were shown as the sister group to the second clades. Although the size of sampling was not large enough for eight Korean Hemerocallis species, the analyses of ISSRs will certainly provide an enhanced view on the phylogeny of species.

The purpose of the study aimed to explore the possibility for natural preservative convergence materials by examining the antioxidant activity and antimicrobial effect of 19 wild plants in Jiri Mountain. Total polyphenols were higher in the order of CS(Camellia sinensis L., 87.9 mg GAE/ g), MP(Mentha piperascens Holmes., 85.1 mg), NN(Nelumbo nucifera Gaertn., 65.0 mg) and PD(Pinus densiflora Siebold & Zucc., 52.8 mg). Total flavonoids were high in NN(25.7 mg QUE / g) and MP (25.4 mg QUE / g). CS(58.1%), NN(47.9%), and MP(40.6%) showed high ABTS radical scavenging ability and the result was similar in DPPH radical scavenging ability. The extracts of HC(Hemerocallis coreana Nakai.), PD, and CO(Cornus officinalis Siebold et Zucc.) showed the highest inhibitory effect on the growth of E. coli. The extracts of PK(Pulsatilla koreana Nakai ex Nakai.), SC(Saururus chinensis Baill.), and MC(Smilax china L.) completely inhibited the proliferation of S. aureus, showing the possibility to be developed as natural preservatives and disinfectants.

본 연구에서는 DMZ 일원인 경기도 파주시 광탄면과 양주군 백석면에 걸쳐있는 박달산(363m) 주변의 관속식물상을 조사하였다. 파주시는 동쪽은 양주시, 서쪽은 한강을 경계로 김포시, 북부는 임진강을 경계로 북한과 접하고 있다. 남쪽은 고양시, 북쪽은 연천군에 접하고 있으며, 북위 37° 42'~38° 07', 동경 126° 41'~127° 01'에 위치한다. 박달산은 파주시 광탄면 경계에 위치하였으며, 현재 명칭은 박달나무가 많아서 박달산이라고 부르고 있으나 예전에는 독수리가 많아서 수리봉이라는 명칭으로 부르기도 했다. 박달산 주변에 분포하는 관속식물 현황은 79과 211속 288종 3아종 36변종 4품종 331분류군으로 조사되었다. 양치식물은 5과 10속 11종 1변종 12분류군, 나자식물은 2과 3속 5종 5분류군, 쌍자엽식물은 63과 154속 208종 3아종 22변종 3품종 236분류군, 단자엽식물 9과 44속 61종 13변종 1품종 78분류군으로 조사되었다. 희귀식물은 취약종(VU)에 속하는 왜박주가리(Tylophora floribunda Miq.) 1분류군, 약관심종(LC)에 속하는 태백제비꽃(Viola albida Palib.), 이팝나무(Chionanthus retusus Lindl. & Paxton) 2분류군이 조사되었다. 특산식물은 키버들(Salix koriyanagi Kimura), 외대으아리(Clematis brachyuran Maxim.), 서울제비꽃(Viola seoulensis Nakai), 오동나무(Paulownia coreana Uyeki), 백운산원추리(Hemerocallis hakuunensis Nakai) 5분류군이 조사되었다. 침입외래식물은 가시박(Sicyos angulatus L.), 단풍잎돼지풀(Ambrosia trifida L.), 돼지풀(Ambrosia artemisiifolia L.) 등 28분류군으로 조사되었다.
