Caulerpa lentillifera belong to Caulerpa genus which is commonly found in tropical and subtropical water. The biggest constituent of seaweed is polysaccharide that has some biological activities as a potential medicine. Therefore, this research aimed to extract and evaluate the antioxidant activity from Caulerpa lentillifera polysaccharide. The extraction was carried out by using water extraction. First, the sample was added with ethanol and soaked overnight at room temperature. On the following day, the sample was added with aquades and put in a water bath at 75°C for three hours. After that, ethanol was added to precipitate the extract. The crude polysaccharide extract percent yield obtained 4.16 %. The crude extract purified by using a column with DEAE-Sepharose with percent yield obtained 14.8 %. Both crude and pure extracts were characterized by analyzing the total carbohydrate and sulfate by using spectrophotometer, functional group by using FT-IR spectroscopy and sugar component by using HPLC. Antioxidant activity was analyzed by using the FRAP method for both crude and pure extract. Moreover, the polysaccharide crude extract gives higher antioxidant activity than the purified extract.

Initial Process

Caulerpa lentillifera is a type of green seaweed that is cultivated in tropical and subtropical areas. The objectives of this study were to determine the characteristics of the sulfated polysaccharides from C. lentillifera and evaluate its antidiabetic activity. In the initial process of this study, samples were macerated with ethanol (1:10). Then, the maceration residue was extracted with an accumulator at 75 °C for three hours. The crude extract yield was 4.16% based on weight seaweed. Ion chromatography purification with DEAE-Sepharose resin provided a yield of 14.8% of crude extract. The monomer analysis of C. lentillifera from the crude extract and purified extract revealed that galactose monomers were dominant and glucose was a minor component. The total carbohydrate and sulfate contents of purified C. lentillifera were higher than those of crude C. lentillifera. Bioactivity tests revealed that purified polysaccharides had higher antidiabetic activity against α-glucosidase enzyme than crude ones with IC50 values of 134.81± 2.0 µg/mL. Purified sulfated polysaccharides of C. lentillifera could potentially be used as an antidiabetic medication.

This study aims to determine the physicochemical quality of seagrape (Caulerpa lentillifera) as a freshness label for products cultivated in different seasons. The applied post-harvest storage experiments compared between, within and without seawater that led to oxidative stress conditions. Water content, malondialdehyde (MDA) compound, total phenolic content (TPC), and chlorophyll content were observed at 0, 3, 6, and 9 days of storage. The storage without seawater showed sharper quality reductions by reaching 20–40% of water loss, 70–90% of MDA production, 15–25% of TPC reduction, and 40–60% of total chlorophyll degradation. The storage within seawater showed lower quality reductions due to the specific growth rates still reaching 5–10%. This study found that the greater the physicochemical quality, the slower the decomposition rates of the stored seagrape during storage. Therefore, the seagrapes’ obvious discoloration occurred earlier in winter, followed by summer and spring. Kinetics of chlorophyll degradation on seagrape in different seasons meet different order-reactions during storage. Furthermore, alternating current electric field (ACEF) treatment with 125 kV/m of intensity for 60 min can lower the spring seagrapes’ physicochemical quality by reaching 10–30% of inhibition, resulting in the shelf-life extension for up to 12 days of post-harvest storage.
