“…The measurement of phenol content was conducted by Folin-Ciocalteu method because it was a quick and simple method to determine the phenolic content of a sample. 16 The most important phenolic compounds contained in the extract of seaweed is phlorotannin. Phenolic compounds had been reported to have antioxidant properties.…”

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. Antioxidant activity of the extract (50 mg/mL) was 41,61±0,02% (E1), 39,16±0,01% (E2), 37,58±0,03% (E3) and ascorbic acid 78.03±0,65 % (22.44 µg/mL) as a standard. The best extract (E1) had inhibited the activity of collagenase by 54.46 ± 0.37%. Conclusion: The brown seaweed (Sargassum plagyophyllum) extract can be used as an active pharmaceutical ingredient for anti-wrinkles cosmetic

Objective: This study aimed to determine the hepatoprotective effect of 50% ethanol extract of seagrass rhizome in terms of serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT) activities in paracetamol-induced rat plasma. Methods:This study included 28 male, white rats randomly divided into seven groups. Groups I and II represented the normal control and control groups, respectively, administered with 280 mg/kg BW of rhizome extract. Group III represented the negative control group induced by a suspension of paracetamol (2g/kg BW). Group IV represented a positive control group administered with Hepa-Q ® at a dosage of 150 mg/kg BW. Groups V, VI, and VII were administered with seagrass rhizome extract at doses of 140, 280, and 560 mg/kg BW, respectively, before paracetamol induction. The test material was orally administered for 17 days. On days 12-17, the rats were induced with paracetamol through the same route. On day 18, blood sampling was performed followed by SGOT and SGPT plasma measurements. Results:Our results revealed that seagrass rhizome extracts could significantly decrease SGPT and SGOT levels in paracetamol-induced rats (p<0.05) compared with those in the negative control group.Conclusion: Thus, seagrass rhizome extracts possess the potential for development as a hepatoprotective agent.

“…Asch., Enhalusacoroides(L.F.) Royle and Halophila ovataGaud results in maximum phenolic content and antioxidant activity exhibited by Cymodocea rotundata, followed by Halodule uninervis. It showed that the Halodule uninervis rhizome had a higher reducing power of 0.557±0.03, it may be due to the unique ability of Halodule uninervis to convert ferrous ion radical into a reduced form (Jeyapragash et al, 2016). When methanol extract of Halodule uninervis tested against gramnegative bacteria (Aeromonashydrophila and Vibrio harveyi) and gram-positive bacteria (Bacillus subtilis and Listeria monocytogenes) it shows higher inhibitory activity against gram-positive bacteria.…”

Halodule uninervisis a flowering plant commonly known as needle seagrass. Halodule uninervis is widely distributed in the Indo-pacific region. In the Indian Ocean, it is found from Geographe Bay in Western Australia. It is a euryhaline species that can tolerate high salinity, grows, reproduce and complete their entire life cycle undersea at the submerged condition. Halodule uninerviswas found to be rich in phenol and phenylpropanoid derivatives such as p-coumaric acid, caffeic acid, p-hydroxybenzoic acid and vanillic acids. As the seagrasses are known to produce unique secondary metabolites as a defense mechanism, many research was targeted towards them in order to search novel potent antioxidants or antibiotics. p-hydroxybenzoic acid acts as an intermediate for several bioproducts that are commercially valuable in food, cosmetics, pharmacy, fungicides, etc. Caffeic acid acts as a free radical scavenger. It has been found that caffeic acid phenyl ester inhibits DNA, RNA and protein synthesis in HL-60 cells; thus, it arrests the growth of human leukaemia cells. The western Pacific and Indian oceans are the indigenous origins of Halodule uninervis. Interesting the fact that Halodule uninervisis an important food for the green sea turtle and dugong and as well as it was used traditionally for wound ailments. These make the seagrass Halodule uninervis a potent plant that needs to be exposed. This review elaborates on the features and recent approaches of the seagrass Halodule uninervis.
