“…[4] Moreover, the previously reports demonstrate that the seed cake possesses various pharmacological properties, such as antitumor, [5] antioxidant, [6] antibacterial, [7] anti-inflammatory, [8] antithrombotic, anticoagulant, [9] hypoglycemic, [10] and hepatoprotective [11] activities, among which antioxidant activity is always related to the cosmetic application. [12] Therefore, with the aim of utilizing the byproduct of C. oleifera, we have researched the potential antioxidative damage compounds from the 70% EtOH extract of C. oleifera seed cake, and in this article, we report the isolation of ten flavonoids, four lignins, three benzenoids, and one alkaloid from the crude extracts ( Figure 1). Furthermore, we have evaluated the crude extracts and isolated compounds for their oxidation resistance ability as well as melanogenesis inhibitory activity, which is considered to be related with the former.…”
