In this study, the skin whitening and anti-wrinkle activity of Abelmoschus manihot (A. manihot) flowers were evaluated as a cosmetic material. A. manihot flowers were extracted using water and 70% ethanol. Tyrosinase inhibitory activity was evaluated to increase concentration-dependent inhibitory activity in both water (AMW) and 70% ethanol extracts (AME), and was found to inhibit melanin biosynthesis at concentrations that did not affect survival in B16F10 cell lines at 10, 25, 50, 75, and 100 ㎍/mL. As a result of measuring the anti-wrinkle effectiveness of A. manihot flowers, 70% ethanol extract (AME) showed higher anti-wrinkle activity than water extract (AMW). Through the results of this study, it is considered that the A. manihot flower extract can be used as a functional cosmetic material with whitening and anti-wrinkle activity.

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.
