본 연구는 화장품 소재로서 금화규(Abelmoschus manihot) 꽃의 미백 활성율 및 항주름 활성을 평가하기 위해 수행하였다. 금화규 꽃은 물과 70% 에탄올을 이용하여 추출하였다. Tyrosinase 억제 활성은 물과 70% 에탄올 추출물 모두 농도 의존적으로 억제 활성이 증가 된다고 평가되었으며, B16F10 세포주에서 생존율에 영향을 미치지 않은 농도인 10, 25, 50, 75, 100 ㎍/mL에서 멜라닌 생합성을 저해하는 것으로 확인되었다. 금화규 꽃의 항주름 효능으로는 collagenase와 elastase의 활성 저해 능력을 측정한 결과 70% 에탄올 추출물이 물 추출물보다 높은 항주름 활성을 보였다. 본 연구 결과를 통하여 금화규 꽃 추출물은 미백 활성과 항주름 활성을 가지는 기능성 화장품 소재로 사용 가능할 것으로 사료된다.

Abelmoschus manihot (Linn.) is a medicinal herbal plant that is commonly used to treat chronic kidney disease and hepatitis. However, its effect on cell proliferation has not been clearly revealed. In this report, we sought to determine the effect of the flower extract of A. manihot (FA) on cell proliferation. Based on our findings, FA increased the proliferation of human diploid fibroblast (HDF) and HEK293 cells. Through cell cycle analysis, FA was found to increase the number of HDF cells in the S phase and G2/M phase. FA also increased the expression of cyclin D1 and enhanced the migration of HDF cells. By administering FA to HDF cells with ≥30 passages, a decrease in the number of senescence-associated β galactosidase-positive cells was observed, thereby indicating that FA can ameliorate cellular senescence. Collectively, our findings indicate that FA increases cyclin D1 expression and regulates cell proliferation.

The problem of odor and environmental pollution caused by livestock manure is spreading greatly as a social issue. To reduce the odor of livestock raised in livestock farms and improve the farm environment, raw materials of Abelmoschus manihot Jinhuakui were put into feed additives to measure the state of odor. It is characterized by being non-toxic and sweet, and Abelmoschus manihot Jinhuakui, which contains abundant nutrients that are beneficial to health in all parts such as roots, stems, and flowers, is a medicinal plant that cannot be discarded. In particular, it has the effect of helping bowel movements because it stimulates bowel movements. Ammonia levels were investigated through the KS X 3279 national standard-applied smart livestock IoT hub sensor pack installed at Flower Garden and Ugil Farm. The purpose of this paper is to reduce the odor that is the most problematic on farms and improve the environment, and it is planned to expand research into deodorants after feed additives. It is hoped that the research results will solve the livestock problem and help livestock farmers.
