잇꽃(Carthamus tinctorius L.)은 국화과에 속하는 두해살이 초본 식물로 한자명은 홍화(紅花), 영명으로는 Safflower를 사용하고 있다. 우리나라의 잇꽃 재배는 2010년 39ha 수준이 재배되다가 2014년에는 76ha까지 확대되었으나 점차 감소하는 추세를 보이고 있으며 2018년에는 55ha가 재배되고 있는 것으로 보고되었고 주산지는 전라남도와 경상북도로 알려져 있다. 잇꽃은 종실을 주로 한약재 원료로 사용해왔으나, 잇꽃의 어린 순을 나물용으로 생산하기 위한 재배가 늘어나는 추세이다. 본 연구는 준고랭지에서 잇꽃 나물을 생산하기 위한 재배 양식과 파종시기별 수량성 및 품질 차이를 구명하고자 수행하였다. 준고랭지에서의 가을 재배에서 파종 후 80%가 출현하기까지의 출현 소요일수는 5~7일로 나타났으며, 재배유형별 수확 도달일수는 시설 재배 9월 29일 파종이 29일로 가장 짧았고 노지 재배에서는 8월 25일 파종이 42일로 가장 길었다. 파종시기별 수확기까지의 유효적산온도는 시설 하우스에서 9월 29일 파종 후 10월 28일 수확하는 작형에서 634.4℃로 가장 낮게 나타났다. 재배 유형별 생육량을 조사한 결과 엽수 및 엽면적은 노지 재배 8월 25일 파종 작형에서 높았고 노지 9월 21일 파종 후 10월 8일 터널을 설치하는 작형에서는 경태 및 엽면적이 4.6mm, 26.2mm²로 유의하게 작은 경향을 나타냈다. 재배 유형별 건조수율은 13.8~15.1% 범위로 파종시기별로 유의한 차이를 보이지 않았으나 당도에서는 노지재배 9월 9일 파종과 9월 21일 파종에서 7.1°Bx, 7.0°Bx로 유의하게 높았고 시설 재배 9월 29일 파종에서 3.1°Bx로 가장 낮게 나타났다. 단위 면적당 생체 수량에서는 노지재배 8월 25일 파종에서 2,223.9kg/10a으로 가장 높았으며, 건조수율로 환산한 건물 수량에서도 노지 8월 25일 파종 작형에서 335.8kg/10a으로 유의하게 높게 나타났다. 노지 재배의 파종시기별 비타민 A 함량은 9월 21일 파종에서 23.3mg/100g으로 높았으며, 비타민 E 함량 또한 25.1mg/100g으로 높은 양상을 보였다.

We investigated the antioxidant activity of ethanol extracts obtained from the flowers of Elsholtzia splendens on Chinese hamster ovary CHO-K1 cells. When cells were treated with E. splendens extracts (ESEs), low concentrations (<12.5 ug/mL) of stimulated cell proliferation via radical generation. Relative mRNA expression of Cu/Zn-superoxide dismutase (SOD) and Mn-SOD in cells exposed to ESEs (1-20 ug/mL) was significantly induced in a dose-dependent manner (p<0.05). In the case of catalase, ESEs had opposing effects; that is, a low-level treatment caused a decrease, and a high-level treatment induced elevated levels (p<0.05). The results demonstrated that components of ESEs exhibit potential antioxidant properties. Also, further studies are required to clarify the active components of Elsholtzia splendens extracts responsible for such biological activities.

The objective of this study was to determine the effect of herb and bio ceramic complex supplementation on growth performance and meat quality characteristics in finishing pigs. Seventy-two crossbred (Landrace ${\times}$ Yorkshire ${\times}$ Duroc) pigs (78.98kg average initial body weight) were used in a 45 days growth assay. Dietary treatments included 1) Control (basal diet). 2) HBC (Herb and bioceramic complex) 0.1 (basal diet + 0.1％ Herb and bioceramic complex) and 3) HBC 0.2 (basal diet +0.2％ Herb and bioceramic complex). For overall period, ADG (Average Daily weight Gain), ADFI (Average Daily feed Intake) and ADG/ADFI increased in Control with no significant difference (p>0.05). Backfat thickness was not significantly different among the treatments (p>0.05). The total cholesterol, HDL (High Density Lipoprotein) cholesterol, LDL (Low Density Lipoprotein) cholesterol, LDL + VLDL (Very Low Density Lipoprotein) cholesterol, Triglyceride and Atherogenic index concentrations of serum in pigs fed HBC 0.2 diet were lower than those of pigs fed Control and HBC 0.1 diets without significant difference (p>0.05). L$\^$*/-, a$\^$*/-, and b$\^$*/- values of M. longissimus dorsi muscle were not significantly different among the treatments (p>0.05). The pH of pigs fed HBC 0.2 diet was significantly lower than that of pigs fed Control and HBC 0.1 diets (p<0.05). In conclusion, growth performance, cholesterol concentration in serum and meat quality were not affected by supplemental herb and bioceramic complex.

Essential oils of various plants have been known for potential biological effects such as antibacterial, antifungal, spasmolytic, antiplasmodial activities and insect-repellent property. Recently, the essential oils have attracted considerable interest in oral disease therapy. This essential oil has been known as being effective on easing sick house syndrome, giving forest aroma therapy effect and acting as repellent against pest. The essential oil of Pinus koraiensi, a native plant from Hongcheon-gun, Gangwon-do, was obtained by hydrodistillation. In light of its medicinal importance, in this study its composition, antibacterial activity and the reducing effect of offensive odor have been analyzed. The composition of essential oil was determined by GC and GC-MS. We have identified 14 compounds, of which 1R-${\alpha}$-pinene (19.38 %), 3-carene (10.21 %), camphene (9.82 %), limonene (9.00 %), bicyclo[2,2,1] heptan-2-ol (8.76 %) and ${\beta}$-phellandrene (7.98 %) were the main components. Essential oils from P. koraiensis, Chamaecyparis obtusa, Abies holophylla and Pinus densiflora were compared in terms of alleviating effect of malodors caused from formaldehyde, ammonia, trimethylamine and methylmercaptan. P. koraiensis essential oil was found to decrease the amounts of ammonia and trimethylamine by 75.17 % and 77.36 %, respectively. Antibacterial activity against Streptococcus mutans and Streptococcus sobrinus, which were known as oral cavity inducer, was investigated using the paper disc agar diffusion method. The inhibition zone was observed against S. mutans (5.97 mm) and S. sobrinus (1.40 mm), respectively. P. koraiensis essential oil shown effective deodorization and inhibitory activity against oral cavity in this study might be potential material in oral sanitary industry.

This study was carried out to find the plant succession stage on highway cut-slopes. In order to analyze succession stage, plant survey with belt transect method was carried out in 1989 and 1995 at Joongbu-highway cut-slopes. The results could be summarized as follows ; The mean plant coverage of cut-slope was 78.3%. Plant coverage of Lower part area was higher than that of upper part area. Pioneer herb species on cut-slope were Miscanthus spp., Arundinella spp., Artemisia spp. etc., and pioneer woody species were Rubus crataegifolius, Robinia pseudoacacia, Pueraria thunbergiana, Pinus spp. etc. Also, among the introduced turf grasses, Eragrostis curvula is the pioneer species. Due to short of maintenance works, Zoysia japonica which has been planted by sodding work was found to decrease or diminish gradually. The ratio of pioneer stage plants, domestic and introduced herb species, seems to decrease, while the ratio of woody species which are advanced stage plants seems to increase. Maintenance works are needed to management and monitoring of plant succession on cut-slope, and use of herb and woody species will be effective.

The methanolic extract of Lysimachiae christinae Herba, which has been used for diuretic, calculi remover and jaundice remedy in oriental countries, was found to possess analgesic and antiinflammatory effect in Freund's complete adjuvant treated rat. From ethyl acetate fraction of the herb a phenyl propanoid isoferulic acid was isolated as an active principle.
