신선한 생강을 80% EtOH로 침지 추출하여 얻어진 추출물을 , EtOAc, n-BuOH로 순차 용매 분획하였고, pancreatic lipase 저해활성, DPPH 및 radical 소거능을 평가하였다. Pancreatic lipase 저해활성을 측정한 결과, EtOAc층의 15.6 /mL의 실험 농도에서 에서 대조군인 orlistat보다 강한 저해능을 확인하였으며, 생강의 주성분으로 잘 알려져 있는 6-gingerol의 경우 같은 농도에

Ginger (Zingiber officinale) is a well-known herb that is widely consumed as spice for the flavoring of foods. As part of our continuing search for bioactive materials, the in vitro pancreatic lipase inhibition and antioxidant properties of an aqueous ethanolic extract of Z. officinale were investigated. The total phenolic content was determined using a spectrophotometric method. The antioxidant efficacies of the extract was studied with radical scavenging assays using DPPH and radicals. Further more, the antiobesity effect of the extract was evaluated by porcine pancreatic lipase assay. In particularly, the pancreatic lipase inhibitory activity of the ethyl acetate (EtOAc)-soluble portion from Z. officinale was significantly higher than that of the other solvent-soluble portions. The results suggest that Z. officinale may have therapeutic potential that may be useful in development of an anti-obesity agent or its precursors.
