Skin care is very important in cosmetics, especially facial treatments. Black mulberry is rich in phenols and is therefor usable in the treatment of acne. It also contains anthocyanin, a well-known antioxidant and a potential source of sun protection. This research aimed to develop a gel dossage from black mulberries (Morus nigra) extracts that would function as an antibacterial, antioxidant and sun blocking facial treatment. This research started with black mulberry fruit extracted through the maceration method by using ethanol (96%). Then, the antibacterial activity of the extract was determined by the disc-diffusion method, while the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were determined by the microdilution method. Antioxidant activity of the extract was determined using the 1,1- diphenyl-2-picrilhidrazil (DPPH) method with vitamin C as a comparison. Furthermore, the extracts were formulated into gel formulas with variations of HPMC, Na-CMC, carbopol 934 and extract concentrations. The products were then physically evaluated for organoleptics, homogeneity, pH, viscosity, and dispersion as well as undergoing a hedonic test, an irritation test, an antioxidant activity test and determining the SPF value of the preparation. The results showed that the black mulberry fruit extract has antibacterial activity with MIC value of 0,025 g/mL against S. epidermidis and P. acnes, while MBC values were 0,025 g/mL and 0,05 g/mL, respectively. The black mulberry extract had antioxidant activity with IC50 value, i.e 146,73 μg/mL vitamin c i.e. 3,17 μg/mL. Formulation with best physical evaluation results showed ina formula containing a carbopol gel base of 934 0,015 g/mL with an extract cconcentration of 0,075 g/mL. This formula resulted in antioxidant activity with an IC50 value, i.e 1004,6 μg/mL, antibacterial activity with inhibition zone 6.83 ± 1.4 mm against and 6.76 ± 0.9 mm against S. epidermidis and P. acnes respectively and an SPF value of 1.9.

Senggani fruit (Melastoma Malabathricum L.) contains anthocyanin that functioning as an antioxidant. Anthocyanin are tremendously sensitive to thermal processes which trigger phytochemical or photo-oxidation reactions that can open anthocyanin rings. The objective of this study is to identify the effect of the simplicia drying method on the antioxidant activity of Senggani fruit extract. Senggani fruit extract was prepared by obtaining samples of ripe fruit, dry sorting, washing, wet sorting, and drying using two methods; sunlight and oven at 70oC. After the simplicia was dry, it was blended and sifted until smooth. The fine simplicia was macerated with 96% ethanol and evaporated to gain a crude extract. The crude extract was assessed with reagents for phytochemical screening. Furthermore, the crude extract was examined for antioxidant activity by the DPPH method. This study implies that the simplicia and crude extract of Senggani fruit from drying in sunlight and oven possess different organoleptic properties such as color, smell, and taste. In phytochemical testing with reagents, it was discovered that anthocyanin compounds were unveiled in drying utilizing sunlight while employing an oven at 70oC; no anthocyanins were found. The antioxidant testing of Senggani fruit extract revealed that the drying method employing sunlight had an IC50 value of 18.8 g/mL while the oven temperature of 70oC owned an IC50 value of 28.3 g/mL. Based on the study results, it can be identified that the simplicia drying method affects the antioxidant activity of the Senggani fruit extract. The drying method in the sun produces extracts with greater antioxidant activity while drying in an oven at 70oC results in a degradation process of anthocyanin compounds, thereby decreasing the antioxidant activity of the Senggani fruit extract.

Abstract Persea lingue Ness is a tree species that lives mainly in temperate forests of south-central Chile. Its leaves are used in ethnomedicine, the fruit is a drupe similar to that of the avocado and has not been studied. The aim of this study was to determine the cytotoxicity in leukemia cell and antibacterial activity, along with some chemical content characteristics of P. lingue fruit and leaf extracts. The antibacterial activity was determined by the inhibition of bacterial growth in liquid medium assay against Gram-positive and Gram-negative bacteria. The leukemia cell lines Kasumi-1 and Jurkat were used to evaluate the cytotoxic activity by using propidium iodide and AlamarBlue assays. Total phenolic, flavonoid, condensed tannin, alkaloid and lipid contents were evaluated in the fruit and in the leaf extracts. The antioxidant activity of both extracts were also elavaluated. Leaf extract presented the highest content of total phenols, condensed tannins and flavonoids, and also the highest antioxidant activity. While the fruit extract has a higher amount of lipids and alkaloids and the high antibacterial activity against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus megaterium and Micrococcus luteus. The leaf extract only showed activity against M. luteus. Concerning the cytotoxic activity, only the fruit extract showed cytotoxicity against the cell lines Jurkat and Kasumi-1. P. lingue fruit extract is a potential source of biologically active molecules for the development of new drugs to be used in some types of leukemia, as well as antibacterial agent.

Abstract Background Dental caries and periodontal disease are the most common chronic infectious oral diseases in the world. Acacia nilotica was commonly known in Sudan as Garad or Sunt has a wide range of medicinal uses. In the present study, antibacterial activity of oral bacteria (Streptococcus sobrinus and Porphyromonas gingivalis), inhibitory activity against glucosyltransferase (GTF) enzyme and antioxidant activity were assayed for methanolic crude extract of A. nilotica bark and its fractions. Methods Methanoilc crude extract of A. nilotica bark was applied to a Sephadex LH-20 column and eluted with methanol, aqueous methanol, and finally aqueous acetone to obtain four fractions (Fr1- Fr4). Furthermore, the crude extract and fractions were subjected to analytical high performance liquid chromatography (HPLC). The crude extract and its fractions were assayed for antibacterial activity against S. sobrinus and P. gingivalis using a microplate dilution assay method to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC), as well as GTF inhibition and antioxidant activity using ABTS radical scavenging method. Results Fractions (Fr1 and Fr2) exhibited MIC values of 0.3 mg/ml against the P. gingivalis. Additionally, Fr2 displayed MBC value of 1 mg/ml against two types of bacteria. Fr4 showed an especially potent GTF inhibitory activity with IC50 value of 3.9 μg/ml. Fr1 displayed the best antioxidant activity with IC50 value of 1.8 μg/ml. The main compound in Fr1 was identified as gallic acid, and Fr2 was mostly a mixture of gallic acid and methyl gallate. Conclusions The results obtained in this study provide some scientific rationale and justify the use of this plant for the treatment of dental diseases in traditional medicine. A. nilotica bark, besides their antibacterial potentiality and GTF inhibitory activity, it may be used as adjuvant antioxidants in mouthwashes. Further studies in the future are required to identify the rest of the active compounds.
