산형과에 속하는 약용작물의 특성은 분열과로서 두 개의 종자가 형성되고 유관(油管)과 주병 혹은 동병이 현저하게 특이한 모양을 나타내고 있어서 산형과 작물분류 뿐만 아니라 더 나아가서 종자의 특성이 식물분류에 이용되고 있다. 종자의 형태는 장방형, 타원형 그리고 난형이며 종피색은 옅은 노란색에서부터 흑갈색까지 다양하다. 종자의 길이는 2∼7mm 그리고 폭이 2∼5mm이다. 이 중에서 가장 작은 종자인 시호는 그 천립중이 1.7g이고 가장 큰 종자인 당귀는 3.9g이다.

Aldose reductase(AR), a rate-limiting enzyme in the polyol pathway, has been demonstrated to cause the intracellular accumulation of sorbitol or galactitol and hence to play key roles not only in the cataract formation in the lens but also in the pathogenesis of diabetic complications such as neuropathy, retinopathy and nephropathy, etc. In a series of investigations to evaluate potential AR inhibitors from medicinal plants, we have shown that some hot water extracts exhibited a significant inhibition of a significant inhibition of bovine lens AR in vitro. Among active plants, the roots of Angelica dahuria (Umbelliferae) were shown to have relatively potent AR inhibitory activity. Systematic fractionation of the ether soluble fraction monitored by bioassay led to isolation of two furanocoumarins, byakangelicin(I) and ter-O-methyl byakangelicin( II), were identified as potential AR inhibitors, their $IC_{50}$ values being 6.2 M and 2.8 M, respectively.

최근 소비자들의 신선한 채소 요구에 따른 수요증가로 볼 때 어린순의 소비는 크게 늘어 날 것으로 보나 국내에서는 무순외에는 거의 개발이 안된 실정이다. 이에 본 연구에서는 약용식물중에서 어린순을 채소로 개발할 수 있는 것을 선발하고자 기초연구로써 수행한 결과는 다음과 같았다. 1. 실험에 사용된 12종의 식물중에서 가걱은 들깨, 메밀, 무등이 낮은 값을 보였다. 2. 발아율은 전체적으로 낮았으나 그중 무, 소엽, 메밀, 항금 및 들깨가 상대적으로 높은 발아율을 보였다. 3. 발아세는 발아율보다 낮으며 그중 소엽, 무, 메밀 및 황금이 상대적으로 높은 발아세를 보였다. 4. 식미특성중 외관상으로 무가 가장 높은 점수를 보였다. 5. 맛은 황금이 가장 높은 점수를 보였다. 6. 조직감은 메밀이 가장 높은 점수를 보였다. 7. 기호도는 소엽이 가장 높은 점수를 보였다.

한국에서 재배되고 있는 당귀속 (Angelica) 식물 7종을 대상으로 핵형 분석을 수행하여 다음과 같은 결과를 얻었다. 당귀속 식물들의 기본염색체 수는 x=11로, 체세포 염색체 수는 모든 종에서 2n = 2x = 22로 관찰되었다. 참당귀의 핵형은 K(2n) = 2x = 20m + 2sm, 일당귀의 핵형은 K(2n) = 2x = 12m + 10sm, 당당귀의 핵형은 K(2n) = 2x =16m + 6sm, 고본의 핵형은 K(2n) = 2x = 22m, 바디나물은 K(2n) = 2x = 18m + 4sm, 구릿대는 K(2n)= 2x = 10m + 10sm 2st, 왜친궁은 K(2n)= 2x = 22t로 각각 구분되었다. 염색체 크기는 $3.56\;{\mu}M-8.91\;{\mu}M$ 사이였다. 고본의 체세포 염색체는 모두 중부 염색체로, 왜천궁은 모두 차단부 염색체로만 관찰되어 다른 종들과 이질적인 핵형을 보였다. 한국에 본포하고 있는 당귀속 식물의 핵형과 러시아, 일본, 중국에 분포하는 식물들의 핵형과 비교에서는 일부 다형현상이 관찰되었다.

To investigate the potency of some natural extracts as skin whitening agents, in this study, 25 natural plants were prepared from natural sources including medicinal plants, such as Angelica dahurica using methylene dichloride, ethyl acetate, n-butyl alcohol, and water as the extraction and/or the partitioning solvents. These natural extracts were subsequently subjected to in-vitro DOPA auto-oxidation test in the media containing human or mushroom tyrosinase as the oxidation promoting enzymes. Most of the extracts showed relatively higher enzyme inhibition(omitted)

A new method for quantitative determination of byakangelicin in Angelicae dahuricae Radix by high performance liquid chromatography was established. A reversed-phase system with a ${\mu}Bondapak$ $C_{18}$ column using THF : dioxane : MeOH : HAc : 5% $H_3PO_4$ : $H_2O$=72.5 : 62.5 : 25 : 10 : 1 : 329 as a mobile phase was developed. Byakangelicin together with ter-O-byakangelicin and oxypeucedanin methanolate, and isooxypeucedanin as an internal reference were detected at 350 nm and the analysis was successfully carried out within 30 min.

This study was carried out to research antimicrobial agents from medicinal plants, Pueraria thunbergiana, Sophora flavescens, Lonicera japonica, Pinellia ternata, Dictamnus dasycarpus, Paeonia lactiflora, Angelica dahurica, Spirodela polyrhiza, Cryptotympana pustulata, Pinus densiflora, Cimicifuga heracleifolia, Bupleurum falcatum, Magnolia kobus, Artemisia princeps, Houttuynia cordata, Forsythia koreana, Arctium lappa, Castanea crenata, Aster tataricus, Citrus unshiu, Gardenia jasminoides, Ledebouriella seseloides, Hovenia dulcis, Prunus sargentii. The ethanol extracts of 24 medicinal plants were tested for the antimicrobial activity against Streptococcus mutans. The extracts of Sophora flavescens, Pinus densiflora, Cimicifuga heracleifolia, Gardenia jasminoides and Ledebouriella seseloides showed antimicrobial activity against Streptococcus mutans. The extracts of Pinus densiflora and Sophora flavescens among these medical plants showed significant antimicrobial activity against Streptcoccus mutans. These results suggested that the extracts from Pinus densiflora and Sophora flavescens could be the potential source of antimicrobial agents against S. mutans.

The aim of this study is to explore the potent phosphodiesterase 4 and 7 inhibitor from various herbal medicines for atopy treatment. In this study, 51 kinds of each herbal medicine, which were extracted with ethanol, was carried out the screening of PDE 4 and 7 inhibition using enzyme inhibitory assay. Of these, 8 species of herbal medicines, Rubus coreanus, Duchesnea chrysantha, Alisma orientale, Rehmannia glutinosa, Angelica dahurica, Thuja orientalis, Astragalus membranaceus and Perilla frutescens were screened as potential inhibitor against PDE 4 and 7. Among 8 species, Duchesnea chrysantha showed poteinial anti-atopic effect on DNCB-induced atopic model. Duchesnea chrysantha extract decreased serum IgE and histamine release significantly.

The hexane and ether extracts from the roots of Angelica dahurica caused a significant inhibition of hepatic drug-metabolizing enzyme (DME) activity. Through systematic fractionation by $SiO_2\;column$ and vacuum liquid chromatography monitoring by bioassays, three furanocoumarins, phellopterin, byakangelicin and tert-O-methylbyakangelicin were isolated as active principles. These components have biphasic responses, both inhibitory and inducing effects on DME system. Tert-O-methyl byakangelicin was found to have the strongest enzyme inhibitory potency.
