  • Lonicerae Folium et Caulis, the folium and stem of Lonicera japonica Thunb., has been used as diuretic, stomachic, antipyretic, analgesic and anti-inflammatory agent in Korea. We isolated a main iridoid, loganin which has some important biological effects from the folium and stem of this plant. Generally, it is known that iridoid compounds have variable contents by the collecting time and a part of plant. The content of main compound is important to evaluate its quality. In order to evaluate the quality of Lonicerae Folium et Caulis, the method of quantitative determination of loganin as a reference standard compound has been developed. (omitted)

  • On the purpose of develcpement of antioxidative compound from natural sources, medicinal plants known to have antioxidant actuvity have been examined concening DPPH radical scavenging activity and SOD-liked activities. Among 8 plants exhibiting the activity, Houttuynia cordata THUNB was selected as resources to search for active compounds due to rareness of study. The antioxidative compounds from Houttuynia cordata THUNB,quercitrin was assayed using a DPPH free radical. The DPPH radical scavenging activity of quercitrin was similar to that of BHA and Ascorbic acid

  • 본 연구는 1979년 6월부터 1981년 5월까지 4회(10일)에 걸쳐 평일도의 식생을 생태학적으로 조사한 것으로 본도의 식물은 총 80과 172속 173종 21변종 4품종, 199종이었으며 상록활엽수는 사스레피나무, 마삭줄을 비롯하여 총 11종으로 섬 전체의 상록활엽수의 분포상태는 특히 빈약하였다. 또한 본도는 동백나무(흉고 직경 30~35cm), 든나무, 사스레피나무, 마삭줄과 같은 상록활엽수가 우점종이었던 것이 대표적인 갑섭(신탄용, 건책용, 방목, 농지리용)에 의해 현재와 같은 10~20년생 곰솔림을 우점종으로 하는 대위적인 천이가 일어날 것으로 생각된다. 특히 높은 인구밀도와 취농율, 경작면적의 증가로 인하여 식물이 심하게 파괴된 것으로 생각되며 한편 월송리의 곰솔림은 보호해야할 가치가 있다고 생각된다. 해안가 식물은 5종(순비기, 해당화, 햇보리사초, 갯맷꽃, 갯방풍)으로 월송리, 동백리, 사동리에 이르는 백사장 부근에 분포되고 있었다.

  • In this study the optimum dyeing conditions and blocking effect of UV deodorization efficiency of Ligustrum japonicum Thunb were investigated. Colorants were water-extracted from Ligustrum japonicum Thunb fruit and freeze-drided to obtain colorants powder. The effects of dye concentration, dyeing temperature, dyeing time, and the number of dipping count were studied. Fastness to dry cleaning, rubbing, perspiration, and light were measured according to KS K 0644, KS K 0650, KS K 0715 and KS K 0700, respectively. In order to examine the dyeability according to dyeing conditions, reflectance of fabrics were measured by using UV/VIS spectrophotometer. The bath ratio was 1:20. Dyeing concentration was 100, 200, 300, 400 and 500% on the weight of fiber. Dyeing time was 20, 40, 60, and 80 minutes. Dyeing temperature was 20, 40, 60, 80, and $100^{\circ}C$. The infrared high pressure dying machine was used. As dyeing concentration increased, dye adsorption increased up to 400% and it slowed down. Dye uptake was increased with raising themperature up to $80^{\circ}C$ and it slowed down. Dye adsorption occurred rapidly at first 20 minutes and then it slowed down and reached almost maximum dye uptake at 60 min. Dye uptake increased by repeated dyeing. Therefore, it is considered that optimum dyeing condition is 400%(o.w.f.), $80^{\circ}C$, 60 min. And repeated dyeing improves dye uptake. Color fastness to dry cleaning and rubbing was good, but light fastness and perspiration fastness was not good. Blocking effect of ultraviolet radiation and deodorization efficiency was good.

  • 쌀을 이용한 식초제조에서 증자 공정과 무증자 공정으로 제조된 쌀과 해당화를 혼합한 조성물을 사용하여 식초를 제조하였다. 1단계로 ethanol 발효를 $25^{\circ}C$에서 12일 동안 진행하고, ethanol 함량을 6%로 조정한 후 $Acetobacter$ $aceti$균을 접종하여 $30^{\circ}C$에서 9일 동안 초산 발효하였다. 식초 발효전에 초산을 첨가하는 공정은 발효의 성공여부를 결정하는 요인으로 나타났으며, 첨가되는 초산의 농도에 의존적으로 최종 식초 제품의 유기산 함량이 증가하였다. 무증자법으로 식초를 제조시 유리 아미노산과 GABA 함량이 높게 나타났으며, 주요 아미노산으로는 glutamic acid, arginine 등으로 나타났다. 본 연구결과는 해당화-쌀 식초 제조시 쌀의 열처리 공정여부가 식초의 품질에 큰 영향을 준다는 것을 보여준다.
