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.

Objectives : The purpose of this study was to investigate the efficacy of Abelmoschus manihot (A-M) on the facial skin by observing the changes in the skin caused by continuous use of the essence containing A-M. Methods : Fifty-one participants were enrolled, 38 were classified as experimental group and 13 were classified as control group. Before the beginning of the test, the skin condition of the participants was investigated with the facial analyzer. An essence containing A-M was provided to the experimental group, and an essence base not containing Abelmoschus manihot was provided to the control group. Participants were asked to use the product in the morning and evening after washing their face. We checked the skin change status every 2 weeks and performed the test 3 times for 6 weeks. Results : In the case of t-zone oil and pores, there was a significant decrease in the experimental group. In the case of moisture, a significant increase was observed in the control group, but the significance was significantly increased when the essence containing A-M was used. In the case of elasticity, it was found that the experimental group continued to increase with the period of use. Conclusion : It is thought that the essence containing A-M will be effective in preventing skin aging through the reduction of t-zone oil, the size of the pores, and the increase in moisture and elasticity.

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.

In this study, we investigated in vitro immune-enhancing and anti-obesity activity of Abelmoschus manihot roots (AMR) in mouse macrophage RAW264.7 cells and mouse adipocytes 3T3-L1 cells. AMR increased the production of immunostimulatory factors such as nitric oxide (NO), inducible nitric oxide synthase (iNOS), interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in RAW264.7 cells. The inhibition of toll like receptor (TLR) 2 and 4 blocked AMR-mediated production of immunostimulatory factors in RAW264.7 cells. In addition, the inhibition of mitogen-activated protein kinases (MAPKs) signaling pathway reduced AMR-mediated production of immunostimulatory factors. From these results, AMR is considered to have immune-enhancing activity through TLR2/4-mediated activation of MAPKs signaling pathway. In addition, AMR inhibited lipid accumulation and reduced the protein level such as CCAAT enhancer-binding protein alpha (CEBPα), peroxisome proliferator-activated receptor gamma (PPARγ), perilipin-1, adiponectin and fatty acid binding protein 4 (FABP4) associated with lipid accumulation in 3T3-L1 cells, indicating that AMR may have anti-obesity activity. Based on these results, AMR is expected to be used as a potential functional agent for immune enhancement and anti-obesity.

The application of the dispersant is indispensable to the manufacture of Korean traditional paper (Hanji). However the mucilage of which extracted from Abelmoschus manihot root has viscosity drop problem in summertime and synthetic dispersant such as polyacrylamide (PAM) and polyethyleneoxide (PEO) have some problems that under the influence of the quality of. water, cohesion, and bad solubility. This study was carried out not only to develop new natural dispersant that can solve such problems but also to investigate the viscosity and papermaking characteristics of Hydrangea paniculata mucilage. There were no viscosity changes between control and treated mucilage that adjusted to pH 9, heated 6 hours at 40 $^{\circ}C$, and stored heating treatment one for a week at 5 $^{\circ}C$. The treatment of mucilage that adjusted to pH 9 and aged for 120 hours at 4$0^{\circ}C$ resulted in viscosity drop. In the hydrolysis of mucilage, galacturonic acid and glucuronic acid contents were decreased by heating and pH adjusting treatments. Wet web stripping quality and physical properties of Korean traditional paper, which used Hydrangea paniculatamucilage were same or superior to the Abelmoschus manihot root.

When the root of Abelmoschus manihot, MEDIC is stored in the water, the mucilage is extracted. The mucilage has contained some of free reducing sugars. We have investigated the change of free reducing sugars by the Bertrand method and also free reducing sugars are detected by paper chromatography and thin layer chromatography. The mucilage is isolated from the root of Abelmoschus manihot, MEDIC and its chemical components are detected. The mucilage and hydrolyzed products are examined by paper chromatography, thin layer chromatography and tested carbohydrates under the usual way. The results are as follow: 1. The mucilage has contained five kinds of monosaccharides which are rhamnose, xylose, arabinose, glucose, galactose and other three kinds of uronic acids. 2. In the mucilage, glucose is the most changeable sugar and the next are arabinase and galactose. 3. Uronic acids, pylose and rhamnose are remained comparatively longer than glucose, galactose and arabinose in the mucilage. 4. The hydrolyzed products of mucilage consisted of rhamnose, xylose, arabinose, glucose, gelactose, ribose, some uronic acids and other unknown compounds. 5. The essence of mucilage isolated from the root of Abelmoschus manihot, MEDIC is complex saccharide, glucose and ribose are newly certified. 6. We can guess that the components of the mucilage are rhamnose, xylose, arabinose, glucose, ribose, uronic acids and other unknown compounds.
