Abstract

Rosella plants are a type of hibiscus plant and can be used as a health drink for various diseases. Rosella flowers have the potential to be used as a source of natural dyes in food. The purpose of this study is to determine the anthocyanin of rosella petals as a chemosensory anion compound. To be used as a chemosensory anion compound, testing needs to be done. The ethanol extract of rosella flower petals was extracted by sonication and the filtrate was evaporated to obtain a red extract. From the results of the extract obtained a rendition of 2.9%. Then the extract was tested as an anion chemosensory with the stages of determining the total anthocyanin content, solvatochromic test, and chemosensory test for saturated anions. The total anthocyanin content obtained was 7.648 grams / 100 grams and the chemosensor test results for saturated anions showed a significant change with the addition of KSCN from pink to clear color. Anthocyanin contained in rosella petals can be used as a chemosensor cyanide anion compound.

Abstract

Cancer is one of the diseases that cause the biggest death in the world. The research for natural compounds derived from marine is very developed at this time, especially in algae. Brown algae have more phenolic content than other types of algae, T. decurrens Bory is one of the brown algae that had taken from the Indonesian island of Dutungan, South Sulawesi. Phenolic groups are also known to be able to inhibit the growth of cancer cells. The purpose of this study is to isolate and identify compounds using spectrophotometer instruments. The isolates obtained were tested for anticancer activity against H460 and MCF-7 cells. Extraction was carried out by maceration method, fractionation was done by chromatography column eluent n-hexane:EtOAc: MeOH by increasing polarity. The structure determination is done based on the interpretation of FT-IR, 1D-NMR 1H,13C, and ESI-LCMS spectra data and anticancer activity test used MTT bioassay. The isolate is known as gallic acid, and the isolate was tested for anticancer activity against H460 and MCF-7 cells. The result is obtained IC50 value for H460 cells 5.69 μg/ml and MCF-7 cells 4.63 μg/ml. As a positive control used cisplatin with an IC50 value of 5.81 μg/ml against H460 cells and MCF-7 cells with a value of 5.59 μg/ml. Gallic acid has a higher toxic effect compared to cisplatin. One phenolic compound has been found in T. decurrens Bory which is gallic acid. Gallic acid has a higher toxic effect than cisplatin, this compound can be used as an anticancer agent.

Abstract

The black mulberry (Morus nigra) plant has been widely developed for its bioactivity as natural medicine. This study evaluated plant extracts' total phenolic and flavonoid content and their correlation to M. nigra stem's antioxidant activity and toxicity. Dry powder from the M. nigra stem was extracted by maceration with 96% ethanol to obtain a thick extract (TE) and fractionated using hexane (HF), ethyl acetate (EAF), and ethanol-aqueous (EF). The samples were analyzed for a compound using reagents and the determination of total phenolic and flavonoid content. The samples were evaluated for antioxidant activity using several parameters and their cytotoxic effects using the BSLT method. Identification of compounds in EAF was confirmed to contain phenolic, flavonoids, alkaloids, saponins, tannins, steroids, and terpenoids. EAF showed higher phenolic and flavonoid content than others. The evaluation of antioxidant activity showed that extracts and fractions from M. nigra stems showed the ability to reduce ions and free radicals. EF sample has activity in reducing Mo (IV) ion by TAC method of 98.82±0.53 µM/mg, indicating substantial antioxidant capacity. In addition, EAF samples showed potential activity in reducing DPPH, hydroxyl, and peroxide radicals in the β-carotene bleaching method with IC50 values of 12.13, 42.06, and 57.6 µg/mL, respectively. Similar activity was also seen in the cytotoxic effect of a robust EAF sample with an LC50 value of 16.31 µg/mL. The results show that EAF can be developed as a raw material for traditional medicine as an antioxidant and anticancer candidate with a significant flavonoid and phenolics content.

Abstract

This experiment aims to determine the correlation of total phenolic and flavonoid content of jati putih leaves fraction (Gmelina arborea Roxb.) towards Antioxidant activity . Sample was extracted by maceration method using ethanol 70% to obtain the ethanol extract (EE), followed by liquid-liquid extraction method to obtain fraction of ethyl acetate (EA) and n-Hexane (EH). The phytochemical screening and determination of total phenolic and flavonoid content were done by colorimetric method. Antioxidant activity were done by DPPH, FRAP and ABTS methods. Phytochemical screening showed positive results for flavonoids, phenolic and saponins. The largest total phenolic content was found on EA (11,59 µg/ml ± 0,3 %b/b EAG) and the largest total flavonoid content was on EA (3,88 µg/ml ± 0,02 %b/b EK). The total phenolic and flavonoid content of Jati putih leaves has a correlation with antioxidant activity. The coefficient correlation of activity on reducingDPPH radical was 56,7% (total of phenolic content) and 57,8% (total of flavonoid content) and on iron reduction power in FRAP method was 99,9% (total of phenolics and flavonoids content). The relationship with the activity in reducing radical ABTS obtained coefficient correlation of 57,0% and 58,1% for total phenolic and flavonoids contents, respectively.

Abstract

Kersen leaves (Muntingia calabura L.) are plants that contain many secondary metabolites, one of which is flavonoids that can act as antioxidants. This study aims to determine the total content of flavonoids which also have the potential as antioxidants in cherry leaves using the DPPH method (2,2-diphenyl-1-picrylhidrazyl) with various filters, namely 70% ethanol, ethyl acetate and n-hexan. Testing of total flavonoid content was carried out using AlCl3 reagent and measured using spectrophotometry at a wavelength of 422 nm. Antioxidant activity testing was measured at an absorption wavelength of 516 nm. The results showed the total flavonoid content of 70% ethanol filter leaf extract as much as 8.13 (mgQE/g), ethyl acetate as much as 8.32 (mgQE/g) and n-hexan as much as 18.96 (mgQE/g). antioxidant activity of cherry leaves using DPPH method (2,2-diphenyl-1-picrylhidrazyl) with filter variations. 70% ethanol extract of cherry leaves has an IC50 value of 7.56 μg/mL, ethyl acetate extract with an IC50 value of 36.05 μg/mL, and n-hexan extract with an IC50 value of 21.33 μg/mL. From the results obtained it can be concluded that the highest antioxidant activity is contained in 70% ethanol extract of 7.56 μg/mL.
