The quality and the nutritional ingredients and the functional activation of Nypa fruticans flower stalk was evaluated in this research. It consisted of 7.5% of water, 13.56% of crude protein, 0.84% of crude fat, 9.25% of crude ash, and 68.85% of carbohydrate. 12 kinds of minerals were identified, where the top 3 of them being K, Cl, and Na in order. There were a total of 15 types of amino acid analyzed, with the main amino acids of arginine 30.25%, aspartic acid 26.90%, and glutamic acid 17.12%. Total polyphenol content was 20,190.73 mg/100 g, and the total flavonoid content was 71.73 mg/100 g. The $IC_{50}$ for DPPH radical scavenging ability was $0.017{\pm}0.00mg/mL$ for Nypa fruticans Wurmb flower stalk, $0.672{\pm}0.01mg/mL$ for blueberry, and $1.282{\pm}0.03mg/mL$ for ginseng. The $IC_{50}$ for ABTS radical scavenging ability was $0.070{\pm}0.00mg/mL$ for Nypa fruticans Wurmb flower stalk, $2.918{\pm}0.13mg/mL$ for blueberry, and $4.131{\pm}0.24mg/mL$ for ginseng. For this reason, it is considered that containing plenty of polyphenol and antioxidant, Nypa fruticans Wurmb is related to antiinflammation. This research will contribute to production of functional foods and high value materials using Nypa fruticans Wurmb.

Purpose: This study investigated the antioxidant activities of water extracts from Hibiscus petals, Moringa oleifera gymnosperm, and Nipa fruticans wurmb. Also, the possibility of their use as a functional cosmetic material and food were searched. Methods: We extracted Hibiscus petals, M. oleifera gymnosperm, and N. fruticans wurmb with water. And then, we measured the content of total polyphenols and flavonoids and the ability to scavenging free groups of ABTS and DPPH to study the antioxidant function. The toxicity of samples evaluated by measuring cell viability. Results: The polyphenol content of the water extract of N. fruticans wurmb was 109 ㎍/mg, which was significantly higher than that of Hibiscus petals (13 ㎍/mg) and M. oleifera gymnosperm (19 ㎍/mg). Radical scavenging ability was also excellent in N. fruticans wurmb, and the cytotoxicity test results of the samples were similar. Conclusions: The water extracts showed antioxidant activity to use for cosmetic materials or natural healing foodstuff.

This study was attempted to investigate the availability of nipa palm (Nypa fruticans Wurmb.) and finger root (Boesenbergia pandurata) extracts as natural cosmetic ingredients. For this, O/W cosmetic formulations with different compositions were prepared. The appearance of the cosmetic formulations was compared, and brightness and color values were measured using a colorimeter. Also, the pH, viscosity, and texture of the cosmetic formulations with different compositions were measured, and the effects of the extracts on the properties of the cosmetic formulations were examined. Finally, the UV transmittance and sun protection factor (SPF) index were observed, and the results confirmed the availability of finger root extract as a natural ingredient for UV protection.

This study was conducted to confirm the change in the contents of the ingredients according to the extraction method of nipa palm. The contents were analyzed by extraction according to the ethanol ratio, extraction time, and extraction temperature. The contents of polyphenols and flavonoids according to the ratio of the extraction solvent were the highest at 36.91 and 27.62 mg/g, respectively, when extracted with 50% ethanol. Polyphenols and flavonoids according to extraction temperature and extraction time showed the highest content of 40.83 and 37.63 mg/g, respectively, when extracted for 6 hours at 60℃. The contents of the major component of nipa palm according to the ethanol ratio were 2.08 mg/g in 70% ethanol for 5-O-caffeoylshikimic acid, 0.10 mg/g for 4-hydroxybenzoic acid in 30% ethanol, and 0.12 mg/g for 3,4- hydroxybenzoic acid in 50% ethanol. It is expected that it can be used as basic research data when developing natural materials such as food and cosmetics through the change in the contents of the ingredients contained in nipa palm according to the extraction methods.

The human skin is an organ that protects the body from physical and chemical factors. The skin is the largest and most massive of the body's organs and is composed of the epidermis, dermis, and subcutaneous tissue. Constant UV exposure to the skin can cause DNA damage, oxidation of proteins, and contribute to adult diseases. Nypa fruticans Wurmb (NF), rich in phytochemicals (polyphenols and flavonoids), has been traditionally used for treating respiratory and other diseases. This study investigated the effects of NF ethyl acetate fraction (ENF) on DNA damage healing and inhibition of wrinkle-related factors in UVB-stimulated Hs68 cells. Westernblotting was used to assess the expression of DNA damage-related proteins and wrinkle-related protein factors. In addition, the wound recovery capability of ENF was confirmed through wound-healing experiments. ENF significantly suppressed the expression of DNA damage-related proteins Phosphorylated H2AX (γ-H2AX), checkpoint kinase 2 (Chk2), protein53 (p53), and Phosphorylated protein53 (p-p53). Furthermore, ENF inhibited the expression of wrinkle-related proteins matrix metalloproteinase-1 (MMP-1), matrix metalloproteinase-3 (MMP-3), and matrix metalloproteinase-9 (MMP-9). High concentrations of ENF also enhanced wound healing in Hs68 cells. ENF is thought to have the potential to heal DNA damage by significantly suppressing the expression of γ-H2AX, Chk2, p53, and p-p53, as well as to inhibit wrinkle formation by suppressing the expression of MMP-1, MMP-3, and MMP-9. These results suggest that ENF can be used as a natural resource to suppress skin damage caused by UVB by regulating the γ-H2AX, Chk2, p53, and MMP pathways in Hs68 cells induced by UVB.

The present study, antioxidant and anti-inflammatory effects were measured of 6 endemic plants in Indonesian extracted by hot water or ethanol. The Nipa Fruticans Wurmb ethanol extract (NFWE) and Orthosiphon aristatus ethanol extract (OAE) showed the highest polyphenol and flavonoid contents of 203.70 and 33.70 ㎍/mg, respectively. Antioxidant activity of OAE was highest in DPPH radical scavenging activity (77.49% at 10 ㎍/mL) and ABTS⁺ radical scavenging activity (93.36% at 10 ㎍/mL). FRAP activity was significantly higher in NFWE than other extracts. Anti-inflammatory effects of 6 endemic plants in Indonesian extracted by hot water or ethanol were examined using nitric oxide (NO) inhibition assays. In the LPS-induced BV2 cells, OAE showed the highest inhibition of NO production without toxicity. The results of this study, suggest that OAE is a potential functional raw material for antioxidant and anti-inflammatory.
