볏짚버섯속 유망버섯인 차신고버섯은 현재까지 1종만이 품종으로 등록되어 있는 실정으로 국내 고유품종 확보 및 버섯재배품종 다양화에 기여하고자 품종육성 연구를 수행한 결과, 차신고버섯 신품종 ‘다산’의 균사생장적온은 25~30℃이었으며 탄소원으로 glucose(maltose), 질소원으로 ammonium chloride(pepton)를 사용 시 균사생장 및 균사밀도가 우수하였고 탄소원과 질소원 무첨가 시 균사는 생장하였으나 균사의 밀도가 비교적 낮았다. 또한 버섯발생 특성은 신품종 “다산”이 초발이 소요일수, 수확 소요일수 및 수량은 각각 12~13일, 6~8일, 118.2g 으로 진향품종에 비해 다소 발이가 늦은 편이나 수량성은 양호하였다. 또한“다산”’ 품종은 갓의 색깔은 대조품종 보다 진하고 갓의 직경은 작았으며 대의 길이는 길고 갓의 직경이 작은 자실체 특성을 가지고 있었다.

차신고버섯(Agrocybe chaxingu )은 소똥버섯과 (Bolbitaceae ) 볏짚버섯속(Agrocybe )에 속하는 버섯으로 차나무나 활엽수의 고사목 또는 뿌리에서 발생하는 것으로 알려져 있으며 아미노산, 무기질이 풍부하고 항암활성 및 혈 압강하효과 등 여러 생리적 기능을 가지고 있는 것으로 보 고된 바 있다. 차신고버섯 신품종 육성을 위해, 기존 등록품 종인 진향차신고버섯과 수집계통인 GWM20502등 4계통 을 교배모본으로 하여 교잡을 통해 육성한 240계통 중 생육 특성이 우수한 dm-001, dm-014계통을 우량계통으로 선 발하였다. 병재배 시험을 통한 선발계통의 재배특성 조사결 과, dm-001계통의 초발이소요일수, 수확소요일수 및 수량 은 각각 12~13일, 6~8일, 118.2g이었으며 dm-014계통은 초발이소요일수가 14~15일, 수확소요일수는 6~7일이었고 수량은 850cc병당 98.5g이었다. 자실체특성에 대한 조사결 과, dm-001계통은 대조품종인 진향차신고버섯과 비교 시 갓은 색깔이 진하고 크기는 작았으며, dm-014계통은 갓 색 깔, 갓 크기는 dm-001계통과 유사하였으나 대길이, 대색이 98.8mm와 백색으로 우수한 품질특성을 가지고 있었다.

In this study, the bioactivities of ethanol (EELS) and water extract (WELS) from the leaf of Lythrum salicaria L. were investigated. In the anti-cancer activity, the growths of both human prostate cancer (DU145) and human colonic carcinoma cell (HT29) were inhibited up 60% by adding 10 mg/ml of EELS. Anti-inflammatory activity of EELS and WELS have been evaluated on lipopolysaccharide (LPS) induced release of nitric oxide (NO) by the macrophage RAW 264.7 cells. EELS and WELS inhibited inflammatory by 57.3 and 46.9% in 10 mg/ml, respectively. In the anti-oxidative activity, IC50 of DPPH radical scavenging activity was respectively 60.71 and 92.90 μg/ml by EELS and WELS. In the anti-diabetic activity, IC50 of α-amylase inhibitory activity of EELS and WELS were respectively 5,250 and 5,020 μg/ml. IC50 of α-glucosidase inhibitory activity was 7.96 and 68.41 μg/ml by EELS and WELS. In the anti-obesity, IC50 of lipase inhibitory activity was 880 and 9,840 μg/ml by EELS and WELS. Finally, EELS and WELS exhibited anti-oxidative, anti-inflammatory, anti-diabetic activity and anti-obesity. It suggests that Lythrum salicaria L. could be potentially used as a resource of bioactive materials for health functional foods.

Eleuthero(Eleutherococcus senticosus Maxim.) cortex is well known as a herb medicine for tonic. This study was performed to improve the quality of dried E. senticosus cortex. Investigation of quality factor and contents of efficient compounds under different steaming times and drying methods were performed to determine the proper processing and drying conditions of Eleuthero cortex harvested on March in annual stems. The proper steaming time for peeling bark to make high quality Eleuthero cortex took less than 20 mins. Eleutheroside B and E contents among drying methods were significantly different at 5% level DMRT. The 50℃ heat drying was the most advisable condition for drying, when drying and keeping contents of effective compounds.

Volatile flavor compounds from the shoot and root of Angelica gigas Nakai were extracted by HE (Hydrodis-tillation extraction), SDE (Simultaneous steam distillation & extraction), and SFE (Supercritical fluid extraction system),and analyzed by GC-MS. The amount and the number of chemical components in essential oils from shoot and root by SFEwas the higher than those by other extraction methods. Respectively, thirty one constituents were identified from the essen-tial oil of the shoot and root by HE, twenty seven and twenty three constituents were identified from the essential oil of shootand root by SDE, thirty one and forty five constituents were identified from the essential oil of shoot and root by SFE. Theresult showed large differences in extraction methods and in plant parts of Angelica gigas Nakai. Also, the bioactive com-pounds in root part was identified as nodakenin and decursinol (11.95% and 8.42%, respectively) by SFE. These results sug-gested that SFE was the best extraction method for the increasing of extraction yield, the determination of volatilecomponents and the increasing of bioactive compounds in the shoot and root of Angelica gigas Nakai.

The mushroom Agrocybe chaxingu was analyzed to evaluate the nutritional value of this potential food. The moisture content was 88.9% in the fruiting body of A. chaxingu, and the proportions of ash, crude fiber, carbohydrate, crude protein, and crude fat were 0.9%, 1.4%, 7.2%, 2.5% and 0.4% by weight, respectively. A. chaxingu contained 1.29 mg/100 g edible weight of vitamin , and the contents of vitamin , vitamin , and vitamin C were 0.15 mg, 0.32 mg, and 18.4 mg per 100 g of wet mushroom. Potassium (3,318 mg/100 g, dry basis) was found at the highest concentration in A. chaxingu. In addition, the mushroom contained many other minerals (all figures are mg per 100 g of dried mushroom) such as phosphorus (909.7), magnesium (141.3), sodium (12.7), zinc (7.4), iron (6.5), copper (2.8), manganese (0.8), and nickel (0.1). The results indicate that A. chaxingu is a valuable nutrient source.
