Abstract

Nature provides various compounds that can provide anti-inflammatory activity, one of which is the compound contained in mangrove roots (Sonneratia alba). In these plants, especially in the roots, there are secondary metabolite compounds such as alkaloids, flavonoids, tannins, triterpenoids and from various reported research results, flavonoids have anti-inflammatory properties. The medicinal preparation that the researchers want to make is a gel preparation that is used for topical treatment therapy. The research was carried out with 15 rats into 5 test groups. Positive control group: given Diclofenac Sodium gel (Voltadex) 20 g (1%), negative control group: given gel without ethanol extract, 2.5% concentration group: given 2.5% ethanol extract gel, 5% concentration group: given 5% ethanol extract gel, 10% concentration group: 10% ethanol extract gel was given. The data was analyzed descriptively and presented in the form of tables and graphs. The research results showed that the Sonneratia alba ethanol extract gel preparation had anti-inflammatory activity. The research results show that the ethanol extract of Sonneratia alba mangrove roots can be used as a gel preparation and in in vivo testing the gel preparation of Sonneratia alba mangrove root ethanol extract has anti-inflammatory activity. The control group of Sonneratia alba mangrove root ethanol extract gel preparations of concentrations of 2.5%, 5% and 10% had a swelling inhibition percentage, which means that Sonneratia alba mangrove root ethanol extract gel preparations of 2.5%, 5% and 10% concentration had anti-inflammatory activity.

Abstract

Sea grapes (Caulerpa racemosa) contain various secondary metabolites with bioactive compounds that function as antibacterial agents. This study aimed to evaluate the antibacterial activity of ethanol extract from sea grapes (Caulerpa racemosa) against Helicobacter pylori. The method used was the agar diffusion technique with paper discs at four different extract concentrations: 500 µg, 600 µg, 700 µg, and 800 µg per disc. Extraction was carried out through maceration using 96% ethanol as the solvent, and antibacterial activity was assessed based on the formation of inhibition zones around the discs. The results showed that all extract concentrations exhibited very strong inhibitory effects on the growth of H. pylori, with inhibition zones of 27.23 mm, 28.51 mm, 29.91 mm, and 31.51 mm, respectively. The higher the extract concentration, the larger the inhibition zone formed. Based on antibacterial activity categorization, Caulerpa racemosa extract demonstrates potential as a strong antibacterial agent against Helicobacter pylori.

Abstract

Salmonella typhi is the primary bacterial cause of typhoid fever, which remains a serious health concern in developing countries, including Indonesia. This study aims to evaluate the inhibitory activity of sea grape (Caulerpa racemosa) extract against Salmonella typhi. The extract was obtained through maceration and tested using the agar diffusion method with paper discs at various concentrations (100, 200, 300, and 400 µg/disc). The results showed that C. racemosa extract inhibited the growth of S. typhi with average inhibition zone diameters of 25 mm (100 µg), 27.3 mm (200 µg), 28.8 mm (300 µg), and 29.5 mm (400 µg). The negative control (distilled water) showed no antibacterial activity. Based on classification, all concentrations exhibited very strong antibacterial activity. A higher extract concentration corresponded to greater inhibitory effect. These findings suggest that C. racemosa has potential as a natural antibacterial agent against S. typhi and may be further developed for alternative typhoid treatment.

Abstract

This study aimed to determine the inhibitory activity of sea grapes (Caulerpa racemosa) against the growth of Propionibacterium acnes, a bacterium that can cause acne on human skin. Sea grapes contain bioactive compounds such as flavonoids and alkaloids which may act as natural antibacterial agents. This research was conducted experimentally in the laboratory using the agar diffusion method with paper discs. The sea grape sample was extracted by maceration using 96% ethanol and tested at concentrations of 100, 200, 300, and 400 µg/disc. Distilled water was used as a negative control. The results showed that the extract was able to inhibit the growth of Propionibacterium acnes, with inhibition zone diameters ranging from 33.9 to 41.2 mm. The largest inhibition zone was found at the concentration of 400 µg/disc. In conclusion, sea grapes (Caulerpa racemosa) have very strong antibacterial activity against Propionibacterium acnes and have potential as a natural antibacterial source.
