Mangosteen Peel

Mangosteen (Garcinia mangostana Linn) is one of the tropical plants grown in many countries, including Vietnam. This is a fruit of high nutrition value and its fruit peels have been used in many traditional remedies. Many scientific publications showed that mangosteen peel contains active ingredients such as xanthone, anthocynin and tannins in this study, we investigated extraction of anthocyanin from fresh mangosteens’ peel of Vietnam in organic solvent and then isolation by supramolecular method. Antioxidant activity was determined in vitro using DPPH reagent. Using 90% acetonitrile acidified with 1% HCl as a solvent, with a ratio of material to solvent of 3 (v/w) at 4°C for 3.5 hours. Anthocyanin content in the extract reached 0.41% dry matter, antioxidant activity DPPH was 51.28 nmol Trolox/mg. Next, anthocyanin was separated by liquid liquid extraction with a solvent mixture (1 water and 2 dichloromethane) and then isolated by supramolecular method with flavocomelin and aluminum chloride. The results of the anthocyanin isolation test by supersymmetry showed that anthocyanin complexes are formed with flavocomelin and aluminum chloride. That way could separate high purity anthocyanins without sophisticate instruments. The antioxidant activity of the super molar complex was 25.39 nmol Trolox/mg. Practical applications Anthocyanin extracted from peels of mangosteen, can be used afterward for additive in some food application as natural coloring substance and antioxidants for preservation.

Abstract. Larasati F, Batubara I, Lestari Y. 2020. The presence of endophytic actinobacteria in mangosteen peel (Garcinia mangostana L.) and its antioxidant activity. Biodiversitas 21: 1488-1497. Mangosteen (Garcinia mangostana L.) is a family member of Clusiaceae which is rich in secondary metabolite compounds that can function as antioxidants. Besides being produced by its host plant, the bioactive compounds can also be produced by endophytic actinobacteria. The purpose of this study was to explore the presence of endophytic actinobacteria from mangosteen peel and determine its antioxidant activity. The actinobacteria were isolated, purified, morphologically characterized, molecularly identified, extracted with ethyl acetate and tested for antioxidant properties. The antioxidant activity was assayed using DPPH (2.2-diphenyl-1-picrylhydrazyl) and ABTS (2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) methods. The components of extracts were separated by Thin Layer Chromatography (TLC) and bioautography was done to determine the antioxidant bands. As a result, five isolates of endophytic actinobacteria in mangosteen peel showed to have difference in aerial mycelium color, substrate mycelium color, and types of spore chains. Based on 16S rRNA gene analysis, AGM3.2 isolate showed similarity with Streptomyces griseochromogenes ATCC 14511 (T) 99.06%. AGM3.1 had similarity with Streptomyces osmaniensis OU-63 (T) 98.35%. Meanwhile, AGM2.3 were similar to Streptomyces xanthophaeus NBRC B-5414 (T) 99.82%, AGM2.2 had similarity with Streptomyces xanthophaeus NBRC B-5414 (T) 98.95%. In addition, AGM2.1 has homology with Streptomyces goshikiensis NBRC 12868 (T) 99.52%. Using both DPPH and ABTS, supernatant of AGM2.1 showed the highest antioxidant activity indicated by 36.96 and 98.80 inhibition, respectively. Antioxidant capacity of ethyl acetate extract of AGM2.1 was 22.22 μg AEAC/mg extract (DPPH) and 20.34 μg AEAC/mg extract (ABTS). Meanwhile, ethyl acetate extract of mangosteen peel had antioxidant capacity by 21.17 µg AEAC/mg extract (DPPH) and 18.75 µg AEAC/mg extract (ABTS). Antioxidant bioautographic analysis of mangosteen peel ethyl acetate extract was compared with alpha mangosteen standard. The results showed that alpha mangosteen presence in the mangosteen extract with the same Rf value of 0.64 with standard. Meanwhile, actinobacterial ethyl acetate extract from AGM3.1, AGM2.3, AGM2.2, AGM2.1 each have the same Rf value with the alpha mangosteen standard. However, the spot for alpha mangosteen had dark red color, while spots of the four actinobacterial isolates showed to have blue color indicating different antioxidant compounds. The blue spot indicates the flavone, flavanone, flavonol, and isoflavone. These compounds include a subgroup of flavonoid compounds. Ethyl acetate extract AGM3.2 does not have spot compounds with the same Rf value as the alpha mangosteen standard. Study clearly shows that endophytic actinobacteria from mangosteen peel have potency as antioxidant.

Tomato lines carrying the genes Aft, atv, Abg, hp-1, and an as yet undetermined gene from the introgression line LA2099 have been combined to produce fruit with elevated anthocyanin content. The antioxidant activity of juice made from anthocyanin-expressing tomatoes was compared to juices made from tomatoes with varied carotenoid content. The contribution of anthocyanin to the total antioxidant activity of the whole fruit in current material is small, but with potential for significant improvement. The increase in flavonoids in the elevated anthocyanin lines has increased water-soluble antioxidant activity of the fruit in vitro.

The antioxidant activity was assessed of fresh juice from Prunus spinosa L. fruit (Rosaceae) growing wild in Urbino (central Italy) by using different cell-free in vitro analytical methods: 5-lipoxygenase test, 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging, and oxygen radical absorbance capacity (ORAC). Trolox was used as the reference antioxidant compound. In the 5-lipoxygenase and DPPH tests the fresh fruit juice of P. spinosa showed good antioxidant activity when compared with Trolox, while the ORAC value was 36.0 μmol eq. Trolox /g of fruit. These values are in accord with data reported in the literature for small fruits such as Vaccinium, Rubus and Ribes. The antioxidant capacity in cell-free systems of P. spinosa juice has been compared with its cytoprotective – bona fide antioxidant activity in cultured human promonocytes (U937 cells) exposed to hydrogen peroxide. The antioxidant activity of red berries has been correlated with their anthocyanin content. The results of this study indicate that the three most representative anthocyanins in P.spinosa fruit juice (cyanidin-3-rutinoside, peonidin-3-rutinoside and cyanidin-3-glucoside) are likely to play an important role in its antioxidant properties.

Few studies had been conducted on the phytochemical profile and the biological activities of Brachychiton rupestris. The antioxidant activity of 85% methanolic extract of B. rupestris leaves and its derived fractions was assessed using five different in-vitro assays which are DPPH• assay, phosphomolybdenum assay (TAC), hydroxyl radical (•OH) scavenging assay, nitric oxide radical (NO•) scavenging assay and permanganate reducing antioxidant capacity (PRAC). The total phenolic, flavonoid and flavonol contents were also determined for the different plant samples using Folin-Ciocalteu, aluminum chloride and aluminum chloride/ sodium acetate methods, respectively. In-vitro cytotoxic activity of the crude extract and its fractions against HepG2 cell line was also evaluated via SRB assay. The ethyl acetate fraction obtained from the aqueous methanolic extract of the plant leaves possessed the most potent antioxidant potential according to the different applied assays (DPPH• SC50 = 25.50±0.76 µg/mL, TAC= 311.98±1.19 mg AAE/g ext., •OH SA= 68.42±0.15%, NO• SA= 33.68±1.98% & PRAC = 62.88±0.27%). It also owed the highest amount of phenolics (TPC= 342.10±2.08 mg GAE/ g ext.) whose majority were flavonoids (TFC= 309.82±3.64 mg QE/ g ext.). A strong positive correlation was found between the total phenolic contents of various plant samples and their antioxidant activity. The butanol derived fraction exhibited the most potent cytotoxic activity (IC50 = 8.60 µg/mL). To the best of our knowledge, it is the first study reporting the antioxidant and the cytotoxic activities of B. rupestris leaves. The study revealed that the B. rupestris leaves could be a good source of natural antioxidants which may be applied in food and pharmaceutical industries. They could also be a new opportunity of discovering anti-mutagenic agents.
