Floristic composition and medicinal plant resources were investigated in six regions, Mt. Sorak, Mt. Jumbong, Mt. Odae, Mt. Hwaak, Mt. Taebaek, and Mt. Bangtae, represent in Kangwon province. This study was conducted from December. 1995 to October, 1997. Vascular plants in investigated regions were composed of 118 families . 529 genera, 1,138 species, 7 subspecies, 223 varieties and 43 fromae, totaling 1,411 taxa. This taxa was correspond to 34.7% of Korean flora, 4,071 taxa (Lee, 1996b),and 73.8% of Kangwon province flora, 1,913 taxa (Kangwondo, 1996), respectively. Among them, medicinal plant resources was composed of 98 families, 238 genera, 337 species, 63. varieties, and 16 formae, totaling 416 taxa (29.5% of investigated 1.411 taxa). Medicinal plant resources in each regions were distributed ranging from 211(31.4%) to 285(33.1%) taxa.

우리나라를 비롯한 동양문화권에서는 천연 약용식물자원의 이용을 통하여 전통적으로 지역 보건향상을 도모해 왔으며 최근 성인병과 난치병 해결을 위한 대체의학에 대한 관심이 증가하면서 약용식물자원을 이용한 건강기능식품 분야가 주목되고 있다. 약용식물자원은 민간에서 약선음식 등에 널리 활용되고 있지만 원료 농산물을 그대로 이용하는 수준으로 광범위한 적용성을 가지는 약선식품용 소재화 기술개발은 약용식물자원의 소비촉진에 크게 기여할 것으로 기대된다. 본 연구에서는 약선식품용 식품소재 개발의 일환으로 약용식물자원의 배합비와 추출물의 제형이 품질특성에 미치는 영향을 조사하였다. 스트레스 경감기능을 보유하는 약용식물자원은 고문헌에 기초하여 선정하였으며 약선원리에 따라 소정의 조건으로 3종(CLP 1, CLP 2, CLP 3) 배합비를 설정하였다. 추출물은 온도를 달리한 열수에 추출하고 유동Ext, 분무건조분말 및 과립으로 제형화 하였고 품질특성은 폴리페놀함량, 용해도, 투과도 및 색도특성을 분석하였다. 약용식물자원 혼합 추출물의 수율은 CLP 2가 65%로 가장 많았으며 1차 추출에서 76%의 수율을 보였고 추출시간대비 수율은 상업적 추출의 경우가 가장 높았다. 유동 Ext의 폴리페놀함량은 CLP 2가 g 당 11~13 mg을 함유하여 가장 많았고 CLP1과 CLP 2는 동등한 수준을 나타냈다. 유동 Ext는 99%의 용해도를 보였으며 투과도는 CLP 3가 52~68%로 가장 낮았으며 추출조건에 따라 색도가 차이가 있었다. 분말형태의 경우 폴리페놀 함량은 분무건조로 제조한 CLIP 2가 15.40mg/g으로 가장 많았다. 부형제로 과립화한 CLP 3가 g당 1.7 mg으로 가장 적었다. 분무건조분말은 98~99%의 용해도를 보였으며 부형제를 사용하여 분무건조하거나 과립화한 시료는 투과도와 명도가 높았으며 적색도와 황색도 및 갈색도가 낮았다. 이상의 결과는 약용식물자원 혼합 추출물은 원료의 조합비와 추출물의 제형은 식품소재화에 따른 품질특성의 영향인자로 작용함을 나타낸다.

In Exp. 1, a total of forty eight multiparous sows were used in a 21-d performance assay. All litters were standardized at eleven piglets within 24h of parturition. Sows were fed one of the four experimental diets 1) CON(basal diet; Control), 2) MP1(basal diet added 0.05% of medicinal plant mixtures), 3) MP2 (basal diet added 0.1% of medicinal plant mixtures) and 4) MP3(basal diet added 0.2% of medicinal plant mixtures). Backfat thickness difference from farrowing to weaning was tended to increase in CON treatment compared to those of medicinal plants mixture(MP) treatments. However, there were not significant differences among the treatments(P>0.05). Sow’s ADFI was increased in sows fed MP2 treatment compared to MP3 treatment(P<0.05). Piglet weight gain was tended to increase in MP1 treatment compared to CON treatment(P<0.05). The glucose concentration of MP3 treatment was higher that of CON treatment(P<0.05). Exp. 2, a total of one hundred twenty weaning pigs ($L{\time}Y{\time}D$, 4.70$\pm$0.63kg average initial body weight) were used in a 20-d performance assay. Weanling pigs were fed treatments diets included 1) CON(basal diet; Control), 2) MP0.05(basal diet added 0.05% of medicinal plant mixtures), 3) MP0.1(basal diet added 0.1% of medicinal plant mixtures) and 4) MP0.15(basal diet added 0.15% of medicinal plant mixtures). Through entire experimental period, as MP increased in the diets, there was an increase in ADG(linear, P<0.067), improvement gain/feed(linear, P<0.018) and a decrease in ADFI (linear, P<0.008). DM digestibility was significantly increased with addition of MP(linear, P<0.004; quadratic, P<0.030). In conclusion, sows fed MP2 had showed less body weight loss and increased weight gain for suckling piglet. In weaning pigs, as supplementation MP from 0.05 to 0.1% in diet had improved growth performance and DM digestibility.

약용식물의 추출물을 식품 제조시에 첨가제로 사용할 목적으로 4종류의 약용식물을 추출하여 각 식물의 기능성을 조사하였다. 골담초, 당귀, 목통, 초피의 나무 줄기를 물과 70% 에탄올로서 추출하여 동결 건조한 후 항균작용, 항산화작용 및 아질산염소거능을 조사하였다. 각 시료의 물과 에탄올추출물의 식중독세균에 대한 항균작용은 그람음성균인 Escherichia coli, Salmonella typhimurium, Shigella sonnei에 대하여 억제 작용을 나타내지 않았다. 그러나 골담초와 당귀의 에탄을 추출물은 2％ 이상의 농도에서 그람양성균인 Listeria monocytogenes와 Staphylococcus aureus의 증식을 억제하였다. 각 시료 물추출물의 전자공여능은 500ppm이상의 농도에서 모두 60% 이상의 전자공여능을 나타내었다. 각 시료의 에탄을 추출물은 목통과 초피가 300ppm에서 70% 이상의 전자공여능으로 물추출물보다 우수하였고 골담초는 물추출물과 비슷한 수준이었으며 당귀는 물추출물보다 낮은 전자공여능을 나타내었다. 각 시료 추출물의 아질산염소거능은 물추출 1,000ppm, pH 1.2에서 당귀 38%, 골담초 40%, 목통35%의 소거능을 나타내었으며 초피가 50%로서 가장 우수한 아질산염소거능을 나타내었다. 각 시료에탄을 추출물의 아질산염소거능은 당귀와 골담초가 물추출물보다 약간 낮은 소거능을 나타낸 반면에 목통과 초피는 물추출물보다 높은 아질산염소거능을 나타내었는데, 특히 초피는 1,000ppm pH 1.2에서 66%의 우수한 아질산염소거능을 나타내었다.

The advent of available DNA barcoding technology has been extensively adopted to assist in the reference to differentiate the origin of various medicinal plants species. However, this technology is still far behind the curve of technological advances to be applied in a practical manner in the market to authenticate the counterfeit components or detect the contamination in the admixtures of medicinal plant species. Recently, a high resolution melting curve analysis technique was combined with the procedure of DNA barcoding (Bar-HRM) to accomplish this purpose. In this review, we tried to summarize the current development and bottleneck of processing related to the Bar-HRM technology for the practical application of medicinal plant species' differentiation in a viable global market. Although several successful results have been reported, there are still many obstacles to be resolved, such as limited number of DNA barcodes and single nucleotide polymorphisms, in particular, only one DNA barcode, internal transcribed sequence (ITS) of ribosomal DNA has been reported in the available nuclear genome. In addition, too few cases have been reported about the identification of counterfeit or contamination with processed medicinal plant products, in particular specifically the case of technology based infusion, jam and jelly products and components in which it is noted that DNA can be thereby degraded during the processing of these products and components.

Seven medicinal plant extracts were tested for antifungal activities against six species of the major turfgrass pathogenic fungi (Colletotrichum graminicola, Pythium spp., Rhizoctonia cerealis, Rhizoctonia solani AG1-1, Rhizoctonia solani AG2-2, and Sclerotinia homoeocarpa) using paper disk diffusion method. Three medicinal plant extracts, including Pinus densiflora showed antifungal activities. In suppression of mycelium growth test, on medium adding P. densiflora extract showed that inhibition rate of mycelium growth were above 80% in 10 mg/10 ml concentration of the extract. The inhibition rate of Pythium spp. was 100% and C. graminicola was 84.3% in 10 mg/10 ml concentrations of P. densiflora extract, respectively. In particularly, the inhibition rate of Pythium spp. was 89.5% in 2 mg/10 ml concentrations of P. densiflora extract. As a result, P. densiflora extract showed high antifungal activity to Pythium spp. and C. graminicola of the turfgrass pathogen in in vitro test.
