“…57 Previous studies with A. marina leaf extracts showed a phenolic content of 18.72 mg of gallic acid/g and an average effective concentration to inhibit the DPPH radical of 9650 ppm, in the iron reduction test a value of 69.1 mg/mL was obtained. 43 Sulmartiwi et al 21 reported the antioxidant activity of A. rumphiana demonstrating the highest activity in the ethanolic extract of leaves (CI 50 492.22 ppm), which agrees with our results. Total phenolics in extracts of A. rumphiana was reported, with 0.9-23.86 mg equivalents of gallic acid/g of extract, the highest values were detected in the fruits of ethyl acetate extracts.…”

“…According to Jacoeb et al 42 Avicennia marina (Rossk) Vierh leaves showed an extraction yield of 9.6% using methanol while ethyl acetate and hexane was 1.28 and 0.6% respectively. Sulmartiwi et al 21 reported the yields of bark extraction of A. rumphiana with hexane of 0.39%, in ethyl acetate 2.8% and in ethanol 3.4%, while in the leaves the reported yield was 3.1% in hexane, 1.4% in ethyl acetate and 6.2% in ethanol. This is consistent with the results obtained that the highest yields are obtained in ethanolic extracts.…”

Introduction: Mangroves are trees or shrubs that are able to grow in brackish water along tropical and subtropical coasts around the world, representing an important ecological conservation system. They have a long tradition of medicinal use and are rich in secondary metabolites. The aim of this research was to evaluate the biological activity and chemical composition of three mangrove species, Avicennia germinans, Conocarpus erectus and Laguncularia racemose, from a natural reserve from Guatemala. Methods: Leaf, bark and root were organically extracted; secondary metabolites were identified by macro and semi-micro tests and TLC, and evaluated for flavonoid and tannin content. Antioxidant activity was evaluated by DPPH, FRAP, TPC and ABTS methods, and antimicrobial activity against seven bacteria. By established protocols it was investigated the larvicidal activity against Anopheles and Aedes, cytotoxicity against Artemia salina and anti-tyrosinase activity by TLC. Results: The best yields were obtained with ethanol in leaves (5.43-26.65%); the highest essential oil yields also in leaves (0.02-0.13%), in both cases A. germinans. Main secondary metabolites were flavonoids, tannins, coumarins, saponins and alkaloids, except C. erectus leaf and bark and A. germinans root. The highest amount of chlorogenic acid was found in A. germinans bark (15.6%), the highest percentage of tannins in L. racemosa root (7.2%), the highest antioxidant activity by DPPH (IC 50 0.2-5.6 mg/mL) in C. erectus leaves, and FRAP (1.2-4.5 g Fe +2 /g of extract) and ABTS (IC50 0.2-11.6 mg/mL) in the bark. Antioxidant activity correlated with TPC, the highest amount in A. germinans bark (149.40-291.39 μg of gallic acid/g extract). None of the species showed larvicidal activity, nor cytotoxicity. Only L. racemosa root showed antibacterial activity against all strains (IC 50 0.62 mg/mL). The ethyl acetate and ethanol extracts exhibited mild anti-tyrosinase activity. Conclusion: Mangroves are a promising potential source of antioxidants and antibacterial compounds.

This study was designed to characterize the phytochemical constituents of Acanthus ilicifolius and Heliotropium curassavicum with antioxidant and nutraceutical activities using different solvents. Analysis of bioactive compounds included the application of common phytochemical screening assays, proximate analysis, FTIR analysis and antioxidant assays. The results showed that the highest extraction yield was observed with methanol. The qualitative phytochemical analysis carried out on the leaves from the methanol extracts of Acanthus ilicifolius revealed the presence of medicinally important constituents such as alkaloids, saponins, phenolics, flavonoids, steroids, cardiac glycosides, tannins and terpenoids. Similarly, H. curassavicum extracts showed the presence of all the phytochemicals including anthocyanin except cardiac glycosides. As a defensive metabolite, both the halophytes accumulate proline in their leaves, but A. ilicifolius has showed relatively high content of proline (37.6 µmol g -1 ) as of true mangrove than H. curassavicum (21.6 µmol g -1 ). The maximum total phenolic content and highest antioxidant potential were obtained in the methanolic extract of A. ilicifolius. The DPPH assay revealed that A. ilicifolius has a maximum of 74.5% radical scavenging activity and comparatively H. curassavicum has a lesser activity of 68.2%. The antimicrobial assays explored that S. aureus and Bacillus sps were susceptible to the extracts at the lowest concentration used (<50 mg/ml) whereas none of the fungi was susceptible to the extracts.

Rhizophora mucronata dan Avicennia officinalis merupakan jenis mangrove yang memiliki potensi kandungan bioaktif yang tinggi. Dalam penelitian ini ekstrak daun mangrove kering dimanfaatkan sebagai sumber zat aktif pada effervescent. Pembuatan granul effervescent ekstrak daun mangrove menggunakan metode granulasi basah. Granul effervescent dibuat dalam lima formulasi dengan memvariasikan kadar ekstrak daun mangrove. Granul effervescent ekstrak daun mangrove yang dihasilkan memiliki karakteristik berwarna kuning kecoklatan, pH 5.05-5.81, kadar air 2,042 - 2,809%, Waktu larut 62,33 - 91, 33 detik, kadar tanin 2,59 - 3,91% dan kadar fenol 1,69 - 3,86 %. Hasil penelitian menunjukkan tidak ada perbedaan signifikan (P>0,05) terhadap perbedaan spesies daun mangrove terhadap karakteristik serbuk effervescent sedangkan formulasi yang berbeda menunjukkan perbedaan signifikan (P<0,05) dari karakteristik serbuk effervescent daun mangrove. Hal ini menunjukkan bahwa daun mangrove memiliki potensi digunakan sebagai minuman effervescent karena konten fenol dan tanin yang dihasilkan. ABSTRACT Rhizophora mucronata and Avicennia officinalis are mangrove species that have high bioactive content potential. In this study dried mangrove leaf extract was used as a source of active substances in effervescent. Effervescent granules of mangrove leaf extracts using the wet granulation method. Effervescent granules are made in five formulations by varying the levels of mangrove leaf extracts. Characteristics effervescent granules of mangrove leaf extract produced have brownish yellow, pH 5.05-5.81, moisture content 2.042-2.809%, soluble time 62.33 - 91, 33 seconds, tannin content 2.59 - 3.91% and phenol content 1 , 69 - 3.86%. The results showed there were no significant(P>0,05) differences in various species of mangrove leaf however the differences of formulation showed there were significant (P<0,05) with the characteristics of mangrove leaves powder effervescent Based on result showed that mangrove leaf have a potencial for effervescent drink because of his phenol and tannin content.
