Mangrove is one of the plants that has the potential to be developed into medicinal plants. However, further research is needed to prove scientifically the content of secondary metabolites in it. This study aims to identify the secondary metabolites contained from leaves and roots in Avicennia alba, Rhizopora apiculata and Sonneratia alba. The leaves and roots of mangroves extracted by maceration using ethyl acetate. The secondary metabolites contained in mangrove samples obtained by doing phytochemical tests through color tests. Phytochemical test results showed that secondary metabolites contained in mangrove Avicennia alba are flavonoids, steroids/triterpenoids, saponins, and tannins/phenols in leaf samples, whereas in its root samples it contains flavonoids and steroids/triterponoid compounds. Sonneratia alba contains flavonoids, steroids/teriterpenoids, saponins and tannins/phenols in its leaf samples, while the root samples contain flavonoids, steroids/teriterpenoids and tannins/phenols compounds. The leaf samples of mangrove Rhizopora apiculatacontains flavonoid and steroid/triterpenoid compounds whereas in its root samples contains flavonoids, steroids/triterpenoids, saponins as well as tannins/phenols.

Mangrove ecosystem services, aside for the fisheries sector, also have ecosystem services in mitigating climate change as carbon sinks and storage. Musi river estuary located in Banyuasin Regency, South Sumatra has the potential of mangrove forests as carbon reserves. The purpose of the study is to analyze the community structure, potential carbon stocks, and economic value of mangroves in the Musi River Estuary. Data were collected at five stations using the 100 m quadratic transect method vertically to the coastline. Data analysis was conducted based on the allometric equation for biomass information, carbon storage, and the economic value of carbon stores. Mangrove ecosystems in the Musi River estuary are Sonneratia alba, Nypa fruticans, Sonneratia casiolaris, and Rhizopora apiculata. Mangrove species that have important roles in the sustainability of ecosystems are Nypa fruticans and Sonneratia alba each with IVI of 145.6 and 101.28, respectively. Carbon storage of mangrove in the Musi river estuary is 107.34 tonC / ha and carbon dioxide absorption is 393.59 tCO2 / ha with a mangrove area of ± 5276 ha. The total estimated economic value of carbon generated from mangrove are Rp174.441.016.895 (free market) and Rp455.872.524.151 (CDM). Keywords: carbon, mangrove, Musi river estuary

Young Leaves

The fractions from young leaves of mangrove Sonneratia alba was studied for its associated secondary metabolites and antioxidant activities. The objective of this study was to determine the secondary metabolite components and antioxidant activity of water, ethyl acetate, and hexane fractions of the young leaves of mangrove S. alba. The fraction was obtained from dry powder of young leaf S.alba using continuous fractionation of crude extracts. The crude extract was attained by 2 extraction methods (soxhlet and maceration) and 2 extraction solvents (methanol and ethanol). Secondary metabolites analyses were qualitatively conducted to detect the presence or absence of phenols, flavonoid, tannin, steroid, triterpenoid and alkaloid. Total phenols were measured using Folin Ciocalteau reagents and gallic acid standard curves whereas antioxidant activity were analyzed using DPPH method (1- 1-diphenil-2-picrihydrasil). Results showed that all fractions contained secondary metabolite components tested. The highest rendement was found in the water fraction fromsoxhletation extract with methanol (6.36±0.29%). The total phenol values were found the highest in the ethylacetatefraction from macerated extract with ethanol (352±9.77 mgGAE/g). Stronger antioxidant activity was also found in ethylacetate  fraction as indicated by the small value of IC50 DPPH namely the ethylacetate fraction with soxhletation extract with ethanol  (3.43±0.25 µg / mL). The results of this study indicate that the semipolar fraction (ethylacetate fraction) has more potential as a source of natural antioxidants.

Medicinal plants are a promising host for endophytic fungi to produce secondary metabolites relevant for food and health. In this study, we evaluate antioxidant activity to determine the species of endophytic fungi isolated from Syzygium aqueum. Endophytic fungi were isolated from leaf stalks through surface sterilization. The fungi’s isolate was identified with morphology and molecular analysis (ITS-rDNA). The pure fungi strain was cultivated on PDB media for 4 weeks, and metabolites were extracted using ethyl acetate. The crude extract of endophytic fungi was examined for its antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH). The pure compound was isolated using the chromatography method, and its structure was determined using spectroscopy analysis involving NMR 1D and 2D. In total, four obtained endophytic fungi were isolated from leaf stalks. The fungi with good antioxidant activity (IC50 59.2 µg/mL) were identified as Beltrania rhombica. The characteristics of the pure compound are white-yellowish powder with IC50 44.2 µg/mL. Based on spectroscopy analysis, the pure compound was identified as 3-(hydroxyl(3,4,5-trihydroxylphenyl)methyl)-3,4-dihydro-2H-pyran-4,5,6-triol.

Cardiospermum halicacabum is one of the most potent medicinal plants used in Indian traditional systems of medicine for the treatment of various diseases, mainly for arthritis. Apigenin is one of the major constituent present in Cardiospermum halicacabum. The present study mainly aimed to estimate the content of major constituent apigenin present in Cardiospermum halicacabum collected from 21 districts of Tamil Nadu by HPTLC method using the marker compound apigenin. The HPTLC method was performed using HPTLC aluminium sheets precoated with Silica Gel 60 GF254 as stationary phase and Toluene: Ethyl acetate: formic acid: methanol (3:6:1.6:0.4 v/v) as the mobile phase. The developed chromatogram was scanned at 254nm using Camag Scanner III. The Rf value of standard apigenin and apigenin in the leaf extract of Cardiospermum halicacabum was found to be in the range of 0.80 to 0.89. Plant collected from Cuddalore district of Tamil Nadu was found to contain relatively high amount of marker compound apigenin than other regions.
