Mangosteen peel (Garcinia mangostana Linn.) contains 593 ppm of anthocyanin. Anthocyanin pigment from mangosteen peel (Garcinia Mangostana Linn.) can be used as an alternative to synthetic dyes. Eutectic solvents are the latest development in extraction technology to extract anthocyanin from its source. The solvent used is pottasium carbonate-glycerol based eutectic solvent. The purpose of this study was to determine the effect of eutectic solvents on the extraction of anthocyanin pigments from mangosteen peel. This research consists of 2 treatment factors namely rmolar ratio of K2CO3: glycerol of 1: 5, 1: 6, and 1: 7 and material: solvent ratio of 1: 4, 1: 6 and 1: 8. Anthocyanin content and color intensity were analyzed using a Spectrophotometer UV-Vis.  Extraction using K2CO3 : glycerol eutectic solvent at a ratio of 1: 7 and the ratio of material: solvent 1: 8 produced the best treatment with extract yield of 46%; anthocyanin content of 263.976 mg/L, and color intensity value of 0.173.

Anthocyanin is a natural pigment that gives red colour on Nipah husk (Nypa fructican) extract. Extraction of anthocyanin compounds used the soxhletation method with independent variables were the type of solvent (aquadest and ethanol with citric acid 3% (w/v)) and extraction time (30, 45 and 60 minutes). This study aims to determine the best type of solvent and extraction time used for extraction of anthocyanin from Nipah husk. The parameters in this study include qualitative and quantitative analysis of anthocyanin (extract yield, total anthocyanin concentration, color intensity, antioxidant activity and analysis of toxicity) from Nipah husk extract. The results qualitatively and quantitatively indicate that Nipah husk extract had anthocyanin content with the highest extract yield was obtained using ethanol-citric acid 3% solvent at 60 minutes extraction time of 0.546 gram / gram. The highest total anthocyanin was obtained using ethanol-citric acid 3% solvent at 30 minutes extraction time of 226.36 mg / L. The highest color intensity was obtained using ethanol-citric acid 3% solvent at 30 minutes extraction time of 0.925. The strongest antioxidant activity (IC50) was obtained using 3% aquadest-citric acid solvent at 30 minutes extraction time of 3.569 ppm. The strongest toxicity activity (LC50) in ethanol-citric acid 3% solvent was 80.023 ppm.

Background: Selecting an appropriate extraction technique and optimization of extraction conditions must be done to improve the efficiency and productivity of natural colorant. Methods: Flesh and peels of four different raw materials viz., beetroot, carrot, pomegranate and grape were extracted independently using 100% ethyl alcohol using cold solvent extraction method adopting 1: 1 and 1: 2 w/v solid to solvent ratio for 24 and 48 hrs, forming 8 treatments replicated thrice in three factorial CRD. The collected extracts were evaporated at 60oC; per cent yield and pigment content were calculated. Result: Extract yield and pigment content were significantly influenced by raw material, solid to solvent ratio and duration of extraction. Extract yield was higher in flesh of carrot and beetroot as well as in peels of grape and pomegranate. Anthocyanin content in grape and pomegranate and betalain content in beetroot were high in peel where as β-carotene content was higher in carrot flesh extract. Per cent yield and pigment content increased with increased duration of extraction and solid to solvent ratio. Requirement of more solvent and longer extraction time are the drawback of conventional extraction methods and there is a growing demand for non-conventional techniques to enhance yield and maintain pigment stability.

The implementation of synthetic dyes gives a better efficiency with higher durability; however, the production process of synthesizing these dyes is more complex, expensive, and involves the use of toxic materials. For these reasons, the production of such dyes can pose harm not only to humans but also to the environment. An alternative for the synthetic dyes is the natural dyes or pigment extracted from plants such as anthocyanin, carotenoid, chlorophyll and many others. These natural dyes are easily extracted from various parts of plants, such as from the fruits, flowers, leaves, and seeds. Regardless of the limited performance of natural dyes, the natural dyes exhibit advantages, including high absorption coefficients, highlight-harvesting efficiency, inexpensive, ecologically friendly, non-toxic, and are easily extractable. Moreover, this research paper is mainly focused on about extraction of anthocyanin dye pigments from Malabar spinach fruits for Dye-sensitized solar cells (DSSC). The experiment was conducted using three different methods; extraction of anthocyanin pigments from Malabar spinach fruits: a.) using pure methanol solvent, b.) using 50% methanol solvent, and c.) using 50% methanol & 1% HCl solvent, and the resulted data were 160.81 mg/L, 64.62 mg/L and 77.65 mg/L respectively. It can be concluded that the extraction of anthocyanin pigments from Malabar spinach fruits using pure methanol solvent has the highest amount of extracted anthocyanin pigment, which is 160.81 mg/L.

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.

Antioxidant-containing cosmetic has antiaging therapy that can inhibit the free radical formation. Mangosteen peel extract has very strong antioxidant activity. To enhance the effect and comfortness of mangosteen peel extract use on the skin, it could be made into nanoemulgel. The article provides the information about method of preparation and evaluation of nanoemulsion-gel. The purpose of this study was to formulate a stable microemulgel of mangosteen peel extractusing halal materials declared halal according to Islamic Shari’a.  the materials used don’t contain carrion, blood, pig and/ animals that don’t conform to Islamic Shari’a. Microemulgel mangosteen peel extract was made by varying plantacare® 1200 UP concentration as cosurfactant (5, 10, 15, 20 and 25%) in the microemulsion and it was incorporated into the gel base. Evaluations were included the antioxidant activity test and organoleptic, pH, viscosity, stability, particle size analysis and panelist test. The antioxidant activity determined by DPPH method showed that IC50 value of mangosteen peel extract was 5.54 ppm. The third microemulsion formula containing cosurfactant of 15% resulted in the best results in that the parameter of the product can be penetrated by ray laser was at particle size of  23.65 nm, was determined by tranmission Electron Microscopy (TEM). Microemulgel containing Viscolam® MAC 10 of seven percent gave the stable formula proofed by freeze thaw and sentrifuga test. The five microemulgel formulations were stable.
