The aim of this study is to evaluate the estrogenic activity of Cucurbita pepo seed extract which includes β-sitosterol and other phytosterols. Sample was extracted from Cucurbita pepo seed by supercritical carbondioxide method and resuspended with ethanol. Estrogenic activity was measured by recombinant yeast assay which detects estrogenic activity using recombinant yeast with high level of estrogenic receptor. However, estrogenic activity of pumpkin seed extract was not found in this study. Based on this data, pumpkin seed extract will not cause estrogenic disturbance.

Pumpkin has long been used as traditional health materials in oriental medicine, pharmacy, medicine, and food industries in many countries. In this study, the water extract and two active components from tendril of young C. moschata Duch. were investigated on inflammation inhibitory activity. The water extract of young C. moschata Duch. showed high cell viability over 95% and it decreased the production of interlukin 6 (IL-6) and tumor necrosis factor (TNF-α) in the capacity of mouse bone marrow-derived macrophages (BMDM) upon lipopolysaccharide (LPS) stimulation. Also, isolated fraction (B4) suppressed the secretion of IL-6 and TNF-α. Among the domestically cultivated pumpkins, B4 fraction contained in the tendril part of them and it comprised of the order of tendril from Cucurbita pepo var. cylindrica, old of C. moschata Duch., and young of C. moschata Duch. These results suggest that water extracts of C. moschata Duch. and purified active compound, rutin, show anti-inflammation activity by suppression of the secretion of IL-6 and TNF-α. It can be applicable as pharmaceutical materials.

반응표면분석법을 이용하여 음료의 제조조건에 따른 늙은 호박의 품질 특성을 모니터링하고 음료 배합비를 설정하였다. 제조조건에 따른 음료의 색상, 향, 맛, 조직감과 전반적인 기호도를 회귀분석한 결과, 는 각각 0.7682, 0.9046, 0.9364, 0.9110, 0.8765이었고 pH, brix 그리고 점도에 대한 는 0.9264, 0.7135, 0.9906으로 나타났으며 색상과 brix를 제외한 다른 품질에서는 5～10%이내의 수준에서 유의성

본 연구에서는 늙은 호박의 효소처리 조건에 따른 추출특성을 조사하였다. 그 결과, pectinase에 의한 영향에서는 효소제 처리를 한 모든 구가 대조구보다 품질 특성이 우수하였으며, 특히 0.15%(w/w) pectinase 처리구의 품질특성이 가장 높게 분석되었다. 혼합 효소제 처리에서는 pectinase와 cellulase의 단독 처리구에 비해 pectinase와 cellulase의 혼합 효소제의 추출율이 높게 나타났다. 최적 효소제 처리조
