Karakteristik Fisika Sediaan Suspensi  Ekstrak Etanol Daun Gaharu  (Aquilaria microcarpa Baill.) dengan Variasi Carboxymethyl Cellulose Sodium (CMC-Na)

ABSTRAK Gaharu (Aquilaria microcarpa Baill.) merupakan salah satu hasil hutan yang memiliki aktivitas antioksidan. Ekstrak etanol daun A. microcarpa terbukti memiliki aktivitas antioksidan yang tergolong sangat aktif. Ekstrak etanol daun A. microcarpa kemudian dibuat menjadi sediaan suspensi dengan variasi CMC-Na sebagai agen pengsuspensi. Penelitian ini bertujuan untuk menentukan pengaruh konsentrasi CMC-Na terhadap karakteristik fisik suspensi ekstrak etanol daun A.microcarpa. Suspensi dibuat dengan variasi CMC-Na pada F1 (0,5% CMC-Na), F2 (1% CMC-Na) dan F3 (1,5% CMC-Na). Evaluasi sediaan suspensi meliputi organoleptis, uji viskositas, uji pH, uji homogenitas serta uji berat jenis suspensi. Nilai evaluasi suspensi dianalisis secara statistik dengan software SPSS 21. Hasil evaluasi fisik menunjukkan bahwa penambahan konsentrasi CMC-Na akan meningkatkan nilai viskositas dan berat jenis sediaan. Kesimpulan dari pengujian ini adalah variasi konsentrasi CMC-Na mempengaruhi hasil viskositas, serta berat jenis suspensi (p<0,05) dan tidak mempengaruhi hasil organoleptis, homogenitas dan pH suspensi. Kata kunci: Gaharu, suspensi, CMC-Na ABSTRACT Gaharu (Aquilaria microcarpa Baill.) is one of the Borneo’s forest products that has antioxidant activity. Ethanol extract of A. microcarpa folium has been shown to have antioxidant activity that is classified as very active. The ethanol extract of A. microcarpa folium was then made into a suspension preparation with variations of sodium CMC as a suspending agent. This study aimed to determine the effect of sodium CMC concentration on the physical characteristics of the ethanol extract of A.microcarpa folium. Suspension was made with variations of sodium CMC in F1 (0.5% sodium CMC), F2 (1% sodium CMC) and F3 (1.5% sodium CMC). Evaluation of suspension preparations included organoleptic, viscosity test, pH test, homogeneity test and suspension specific gravity test. The suspension evaluation data were analyzed statistically with SPSS 21 Software. The physical evaluation results showed that the addition of sodium CMC concentration would increase the viscosity and specific gravity of the preparation. The conclusion of this test was that variations in the concentration of sodium CMC affected the results of viscosity and suspension specific gravity (p <0.05) and did not affect the organoleptic yield, homogeneity and pH of the suspension.

Treatment Of Diabetes

This study aims to find the treatment of diabetes using natural materials by exploring plants in the province of East Nusa Tenggara. his research was conducted out by extracting the Strychnos nitida G.Don stem using a method of maceration by ethanol 70%. Ethanol extract was then fractionated using n-hexane and ethyl acetate. Simplicia from maceration and fractionation results were then tested for antioxidant activity, α-glucosidase inhibition activity and identification of active compounds. The results showed that ethyl acetate fraction had the lowest IC50 value of 86.83 μg / ml. Results of the α-glucosidase activity test showed that ethyl acetate fraction and n-heksan fraction at 900 ppm had the highest percentage of inhibition of 34.23% and 33.89%. Identification using LCMS/MS method showed that ethyl acetate fraction consist of Benzenemethamine, N, N-dioctyl- as an antioxidantcompound and compound 24-methyl-5-cholestone-hexol as an antidiabetic compound. From the results of this study, we concluded that the extract of kayu ular Strychnos nitida G.Don stem has inhibition activity toward α-glucosidase enzyme.

Free radicals and reactive species are widely believed to contribute to the development of several diseases by causing oxidative stress and eventually oxidative. Vernonia amygdalina (Astereacea) is a small shrub or tree between 1 and 5m high growing throughout tropical Africa. Plants are generally known as bitter leaves is well cultivated and is a general market for merchandise in several countries. The purpose of this study was to determine the antioxidant activity of hexane fraction from ethanol extract od Frican leaves (Vernonia amygdalina Del.). The method used in this study was the DPPH (1,1-Diphenil-2-Picrylhydrazyl) method. The result of phytochemical screening showed that ethanolic extract of African leaves contained a composition of secondary metabolites of alkaloids, flavonoids, tannins, steroids/triterpenoids and saponins. The antioxidant activity of the extract of n-hexane fraction was classified as very weak with an IC50 value of 317.98 ppm.

New Treatments

Diseases mediated by the immune system are difficult problems to treat such as human immunodeficiency virus (HIV) and other lethal viruses. Infections that occur in normal people are generally brief and rarely leave permanent damage. Treatment of this disease requires an aggressive and innovative approach to the development of new treatments so that it requires the role of immunomodulators to improve the immune system. A substance that acts as an enhancer or immune enhancer can be obtained by using herbs that are efficacious as immunostimulants. One of the herbs used is herbal binara (Artemisia vulgaris L) which has been studied as a potential immunomodulator with high antioxidant activity. Previous research also stated that red shoots (Syzygium oleana) were studied as potential immunomodulators with high antioxidant activity. Several other species such as Syzygium samarangense have 16 flavonoida compounds which show pharmacological immunological activity. The purpose of this study was to determine the content of secondary metabolites of ethanol extract of herbal binara (Artemisia vulgaris L.) with red shoots (Syzygium oleana) and to determine the best dose of extract from the ethanol extract of herbal binara (Artemisia vulgaris L.) with red shoots (Syzygium oleana) can reduce the volume of swelling of mouse feet. Examination of the chemical content of secondary metabolites from the ethanol extract of herbal binara (Artemisia vulgaris L.) with red shoots (Syzygium oleana) is carried out by chemical screening and characterization of simplicia and extract. The method used is the slow type hypersensitivity method. In this test the independent variable is the secondary metabolite of ethanol extract of herb binara (Artemisia vulgaris L.) with red shoots (Syzygium oleana) with four concentrations (50, 100, 200 and 400 mg / kgBB). The positive control used by Stimuno dose is 32.5 mg / kgBB

AbstractSample particle size is an important parameter in the solid–liquid extraction system of natural products for obtaining their bioactive compounds. This study evaluates the effect of sample particle size on the phytochemical composition and antioxidant activity of brown macroalgae Sargassum cristaefolium. The crude ethanol extract was extracted from dried powders of S.cristeafolium with various particle sizes (> 4000 µm, > 250 µm, > 125 µm, > 45 µm, and < 45 µm). The ethanolic extracts of S.cristaefolium were analysed for Total Phenolic Content (TPC), Total Flavonoid Content (TFC), phenolic compound concentration and antioxidant activities. The extract yield and phytochemical composition were more abundant in smaller particle sizes. Furthermore, the TPC (14.19 ± 2.08 mg GAE/g extract to 43.27 ± 2.56 mg GAE/g extract) and TFC (9.6 ± 1.8 mg QE/g extract to 70.27 ± 3.59 mg QE/g extract) values also significantly increased as particle sizes decreased. In addition, phenolic compounds epicatechin (EC), epicatechin gallate (ECG), epigallocatechin (EGC), and Epigallocatechin gallate (EGCG) concentration were frequently increased in samples of smaller particle sizes based on two-way ANOVA and Tukey’s multiple comparison analysis. These results correlate with the significantly stronger antioxidant activity in samples with smaller particle sizes. The smallest particle size (< 45 µm) demonstrated the strongest antioxidant activity based on DPPH, ABTS, hydroxyl assay and FRAP. In addition, ramp function graph evaluates the desired particle size for maximum phytochemical composition and antioxidant activity is 44 µm. In conclusion, current results show the importance of particle size reduction of macroalgae samples to increase the effectivity of its biological activity.
