Background: Turbinaria conoides is one of abundant brown macroalgae in Indonesian oceans contains phenolic derivatives. Phloroglucinol is a multifunctional phenolic derivative in brown algae. Phloroglucinol has been known to have activity inhibitor tyrosinase, because phloroglucinol is copper chelating agent. The antioxidant and the tyrosinase inhibitor activities are parameters of the skin lightening active ingredient. The mechanism of tyrosinase inhibitors is to decrease skin pigmentation by inhibit the catalytic steps of the enzyme to the pigmentation associated with melanin production in the pathway of melanogenesis. Antioxidant activity protects skin against oxidative stress mediated by UVR. Numerous report have determine phenolic compound of T. conoides as antioxidant but none is reported as tyrosinase inhibitor. Objective: The objective of this study is to determine the activities of T. conoides as antioxidant and tyrosinase inhibitor. Methods: Turbinaria conoides were extracted with ethanol with different concentration (30\%, 50\% and 70\%) by maceration method. Crude ethanolic extracts of T. conoides were determined its total phenolic content, antioxidant activity (DPPH) and tyrosinase inhibitor. Results: E50 showed the highest total phenolic content (27.63{\textpm}1.05 mg PGE/g extract). Antioxidant and tyrosinase inhibitor activities of E50 showed IC50 value of 215.96 μg/mL and 188.85 μg/mL, respectively. Conclusion: Ethanol extract of Turbinaria conoides is potential as antioxidant agent and tyrosinase inhibitor.

Background: Sea algae are widely used as food and cosmetics in the world. There are several algae including brown algae which are us for human used to maintain health and skin care. Brown algae have various potential biological activities because contain substantial phytochemical constituent. Numerous report has identified phytochemical compound of Sargassum sp. extract but the activity as anti-collagenase almost none. Objective: To study the antioxidant, and anti-collagenase activity of Sargassum plagyophyllum extract as active pharmaceutical ingredient for anti-wrinkle cosmetics. Methods: Sargassum plagyophyllum obtained from Pasauran Beach, Banten, West Java, Indonesia. The extract Sargassum plagyophyllum extracted with three concentration ethanol-water: (E1) ethanol 25\%, (E2) ethanol 50\% and (E3) ethanol 75\%, by using maceration extraction method for 24 h, thrice. The extract was evaluated include total phenolic content, antioxidant activity, and the best extract was tested for the anti-collagenase activity. Results: Total phenol in the extract were 0.588 \± 0.01 (E1), 0.272 \± 0.01 (E2), and 0.220\± 0.03 (E3) mg PGE/ 100 g extract, respectively.

Introduction: Diabetes mellitus (DM) is an endocrine disorder characterized by high blood glucose levels. One of the approaches for treating DM is by regulating the postprandial blood glucose via inhibition of \α-glucosidase enzymes. Seagrass is known as a plant containing bioactive compounds, especially for therapy antidiabetic. This research aims to evaluate the \α-glucosidase inhibition activity of three species seagrasses (Enhalus acoroides, Thalassia hemprichii and Cymodocea rotundata) from the Banten Bay, Indonesia. Methods: The extracts of all parts (root, leaf, and stem) from three seagrasses were prepared with maceration method using 80\% ethanol solvents. The \α-glucosidase inhibitory activity was conducted by microplate reader at 400 nm using acarbose as a positive control. Furthermore, the kinetics of \α-glucosidase inhibition, phytochemical screening, and total phenolics content were evaluated against extract which has the most potential \α-glucosidase inhibition. Results: The result showed that the 80\% ethanol extracts of Enhalus acoroides (IC50 values 168.15 \± 2.71 g/mL) had the most potential \α-glucosidase inhibitors activity compared with the positive control acarbose, Thalassia hemprichii and Cymodocea rotundata (IC50 values 197.27 \± 3.07 g/mL, 425.86 \± 5.15 g/mL and 429.28 \± 8.89 g/mL). The kinetic type of inhibition against \α-glucosidase was noncompetitive inhibition. The phytochemical compounds were phenols, flavonoid, terpenes, and tannin with the total phenolic content was 28.76 \± 2.46 mgGAE/g. Conclusion: Enhalus acoroides has the strongest inhibitor of \α-glucosidase and can be further developed for DM therapy agents.

Background: Thalassia hemprichii have reported containing antioxidant effects. However, information on other biological activities relating to the anti-wrinkle properties is limited. The free radical scavenging activity and enzyme inhibitory activity of the plant extracts investigated that they can help restore skin elasticity and thereby slow the wrinkling process. Objective: To evaluate in-vitro antioxidant and anti-collagenase activity of T. hemprichii as a potent ingredient for anti-wrinkle cosmetic. Methods: T. hemprichii was extracted with ethanol 100\% (E1) 75\% (E2) and ethanol 50\% (E3) using maceration extraction method for 24 h, thrice. The extract was examined for total phenolic content, antioxidant activity compared with vitamin C, and the best extract was tested for the inhibitory activity of collagenase. Results: The total phenolic content of T. hempricii extract was 0,525 \± 0,016 mg GAE/100 g extract (E1) 0,538 \± 0,006 mg GAE/100 g extract (E2) and 0,558 \± 0,090 mg GAE/100 g extract (E3) respectively. The antioxidant activity (\% inhibition) of the extract was 38,035 \± 0,252 \% (E1), 52,502 \± 6,225 \% (E2) and 57,261 \± 0,505 \% (E3). Ascorbic acid as a positive control of antioxidant activity showed much higher \% inhibition than the sample with 78,055 \± 0,756 \%. As the best extract from antioxidant activity, E2 and E3 have inhibited collagenase activity with 51,809 \± 0,164 \% and 52,212 \± 0,735 \% at 20\μg/mL respectively. Conclusion: In general the (T. hempricii) extract can be used as a potential active ingradient for anti-wrinkles cosmetic.

Background: Thalassia hemprichii (Ehrenb.) Asch is one of the commonly found seagrasses spread over the coast of Indonesia and has not been utilized. Previous studies have reported its potency as an antioxidant, however, studies on optimal extraction conditions using ethanol as a solvent to obtain higher antioxidant activity are still limited. Objective: The purpose of this study is to optimize the extraction condition for obtaining the highest antioxidant activity and total phenolic content of the seagrass T. hemprichii. In an addition, percentage yield of extract was also evaluated. Methods: In this study, factorial design with independent factors of ethanol concentrations (50\%, 70\%, and 100\%), the use of HCl 1 N (Yes/No), and temperature (300C, 600C) was developed. The analysis of variance (ANOVA) was used to determine the significance of the above factors towards antioxidant activity and total phenolic content. The antioxidant activity was evaluated with 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and the total phenolic content was determined by Folin-Ciocalteu method. Results: The highest antioxidant activity (IC50=83.48 \μg/mL) was shown in sample R1 (extracted with 50\% ethanol, added with HCl 1 N, and 600C). The sample was also showed total phenolic content 41.03 mg GAE per gram and 22\% yield extract. Among the factors examined, the used of HCl 1 N showed the most significant effect to the antioxidant activity and the total phenolic content, with the p-value of 0.048 and 0.034 respectively (p\<0.05). Conclusion: This extraction condition can be applied to obtain higher antioxidant activity and total phenolic content from the plant.
