추출시간에 따른 약용식물추출물의 활성변화에 관한 연구

When extracting medicinal plant which is used as effective medicine, there`s something to be considered. You should consider the collecting condition like collecting time, place, part and extracting condition like extracting method. Despite the effect differences by collecting and extracting conditions, the differences of efficacy appeared by some condition(extracting time) were not big problem till now. But, as increased interests in standard extracting condition of medicinal plants, more scientific study about extraction time is required. Therefore, this study used the free radical scavenging activity test and absorbance method in ultraviolet-ray area and focused on checking the occurrence of effect difference by extracting time. Moreover, in case of doing extraction test by time difference, we could notice that extracting time is very important factor and effect is varied by time. With this result, we found that proper time condition can make better data and increase the possibility of plant`s extracts standardization.
