INTISARI Umbi bawang dayak memiliki kadar antioksidan yang sangat tinggi. Penelitian ini bertujuan mendapatkan formula masker gel feel off ekstrak umbi bawang dayak yang menghasilkan pembentukan film yang baik berdasarkan hasil evaluasi fisik. Masker gel peel off dibuat dalam 3 formula dengan parameter perbedaan konsentrasi PVA. Formula 1 PVA 10 %, formula 2 12%, formula 3 PVA 13%. Proses pembuatan ekstrak dengan cara maserasi, kemudian dipekatkan dengan evaporator dan dibuat sediaan masker gel peel off dengan penambahan eksipien. Hasil uji organoleptis menunjukkan parameter aroma, warna dan tekstur tidak berbeda nyata antar formula. Hasil uji fisik menunjukkan formula 3 dengan PVA 13 % menghasilkan masker gel peel off yang paling baik dibandingkan dengan formula 1 dan 2, dengan nilai viskositas 3,833 cps, pH 6, homogeny, waktu mongering < 15 menit dan uji daya sebar 5, 815 cm. Kata kunci: bawang dayak, masker gel peel off, PVA. ABSTRACT Bawang Dayak bulbs have a very high antioxidant content. This study aims to get the mask gel feel off formula the bawang Dayak bulb extract that results in good film formation based on the results of physical evaluation. The mask gel Peel off is made in 3 formulas with different parameters of PVA concentration. Formula 1 PVA 10%, formula 2 12%, formula 3 PVA 13%. The process of preparing the extract by maceration, then concentrated with evaporator and made gel mask preparation with the addition of excipients. The results of organoleptic tests showed the parameters of aroma, color and texture were not significantly different between the formulas. Physical test results showed that formula 3 with PVA 13% yielded the best peel off gel mask compared with formula 1 and 2, with viscosity value 3,833 cps, pH 6, homogeny, mongering time <15 min and spreading test 5,515 cm. Keywords: Bawang Dayak, mask gel peel off, PVA.
Pharmaceutical raw materials from agriculture or collection of wild plant chemical content can not be guaranteed always constant due to variable seed, the body, the climate, the conditions (age and how to harvest). The content of the chemical compounds responsible for the biological response must have chemical specifications, namely the composition information (type and concentration). The efficacy of traditional medicine based on the chemical compound. Therefore, the assay of the active substance a crude drugs and extracts needs to be done to ensure that a traditional medicinal products can be assured of quality and usefulness. The assay performed on botanicals and 50% ethanol extract of leaves of Stevia rebaudiana. The assay of the crude drugs and extracts from the stevia leaf area of Malang, Tawangmangu, and Bogor using High Performance Liquid Chromatograph method. Results of the assay stevioside on simplicia and stevia leaf extract obtained stevioside levels in simplicia stevia leaves from Malang, Bogor, Tawangmangu consecutive namely 5.65%; 3.89%; 1.59%. Stevioside levels in the stevia leaf extract of Malang, Bogor, Tawangmangu respectively, are 14.14%; 22.40%; 66.65%.Key word: Stevia rebaudiana leaf, stevioside content, High Performance Liquid Chromatograph
esum leaves are one of the plants that are widely available in West Kalimantan and are used by the community as vegetables or cooking spices. Research on the chemical content of kesum leaves has been carried out by several researchers, but research on whether there are differences in the chemical content obtained from the extraction with several types of solvents in kesum leaves has not been carried out. Therefore, in this study, the chemical content of kesum leaves will be tested. The method used is to test the presence of chemical compounds by phytochemical screening on several kesum leaf extracts using different solvents, namely 70% ethanol, 50% ethanol, 96% ethanol and methanol. The observations obtained were then analyzed descriptively and presented in tabular form. The results of the phytochemical screening test showed that the kesum leaf extracted in 70% ethanol, 50% ethanol, 96% ethanol, and methanol solvent contained phenols, flavonoids, saponins, and tannins. Moreover, extract of ethanol 70% and ethanol 50%, also contain terpenoids amd alkaloids, which were not detected on ethanol 96% and methanol extract.
ABSTRAKPenentuan kadar flavonoid pada ekstrak etanol daun andong merah dan daun andong hijau, yang di tentukan dengan metode kolorimetri menggunakan spektrofotometri Uv-Vis, bertujuan untuk mengetahui kadar flavonoid pada ekstrak etanol daun andong merah dan daun andong hijau, analisis flavonoid dilakukan pada panjang gelombang = 433 nm, kadar flavonoid total dihitung dengan persamaan regresi linear y = 0,00757x + 0,0324 dengan koefisien relasi r² = 0,997842544. Penentuan kadar flavonoid total dilakukan dengan spektrofotometri berdasarkan pada kemampuan flavonoid membentuk kompleks dengan AlCl3. Kadar flavonoid yang di peroleh dari ekstrak etanol daun andong merah adalah 0,329 % dan ekstrak etanol andong hijau adalah 0,4354 %. Kata kunci : Flavonoid, daun andong merah, daun andong hijau, kolorimetri. ABSTRACTDetermination of flavonoid content in the ethanol extract of red andong leaves and green andong leaves, which was determined by the colorimetric method using Uv-Vis spectrophotometry, aims to determine the flavonoid levels in the ethanolic extract of red andong leaves and green andong leaves. nm, the total flavonoid content is calculated by linear regression equation y = 0.00757x + 0.0324 with the coefficient of relation r² = 0.997842544. Determination of total flavonoid content was carried out by spectrophotometry based on the ability of flavonoids to form complexes with AlCl3. The flavonoid content obtained from the ethanol extract of red andong leaves is 0.329% and green andong ethanol extract is 0.4354%.
Prevention and treatment with synthetic antidepressants has many side effects that affect the central nervous system and usage must be under the supervision of a doctor. Whereas prevention and traditional medicine relatively do not cause side effects, are inexpensive, and easy to obtain. One example of traditional medicine from natural ingredients, which can provide an antidepressant effect is ginger rhizome. This research aims to determine whether ginger rhizome have antidepressant effects on male white mice. Antidepressant effect testing was carried out on male white mice (Mus musculus) using the forced swim test method. The part of the plant used is the rhizome of the ginger plant. Curcuma rhizome is made with juice and given orally with a concentration of 20%, 40%, and 60%. The negative control used is Na CMC 0.5%, while the positive control used, namely amitriptilyn. The parameters observed were the duration of immobility time, swimming time and climibing time (in seconds) which were calculated from minutes 3-6 for 6 minutes, and statistical tests were carried out with a confidence level of 95%. The results showed that at a concentration of 40% the curcuma rhizome juice had a significant value (p> 0.05) which means that there was no significant difference in antidepressant effect (%) from the juice of temulawak 56.31% and amitriptylin 78.78%Keywords: ginger rhizome, antidepressants, the forced swim test
