Abstract

Background: cinchona extract contains quinoline alkaloids, has telangiectatic activity, is practically insoluble in water so penetration into hair follicles is low and requires a delivery system, namely cream. Objective: to determine the formula of cinchona extract cream with good activity, physical stability and safety. Methodology: cinchona bark extraction (soxhletation method), phytochemical screening, cinchona extract dosage determination, optimization of cream formula using Design Expert software version 11. Evaluation: pH, adhesion, spreadability, viscosity and cycling test stability. Activity test using guinea pigs (Cavia porcellus) for 14 days, parameters of hair length/2 days, hair mass (14th day). Acute dermal irritation test using rabbit (Orycogalus cuniculus) by erythema and edema index parameters. Results: cinchona extract (13.32% yield) contained quinoline alkaloids, cinchona extract dosage was 20% (p<0.05). The optimum formula is F2 with characteristics: pH 6.48±0.07, adhesion 1.16±0.07, spreadability 4.99±0.85 and viscosity 3067±416.45, has good physical stability. Activity test: test area hair length 13.54 – 62.14% longer than normal control and 10.10 – 49.17% than negative control. The hair mass of test area was 122.91% heavier than normal control and 104.48% of negative control (p<0.05). Cinchona extract and excipients were non-irritant. Conclusion: Cinchona extract cream (20%) has hair fertilizer activity, good physical stability and safety.

Abstract

Sinkonin praktis tidak larut dalam air, sedikit larut dalam kloroform dan alkohol. Hal ini berdampak pada rendahnya penetrasi transfollicular sinkonin, karena hanya bahan aktif hidrofilik yang mampu melewati hair follicle. Dengan demikian dibutuhkan satu sistem penghantaran yang mampu menurunkan hidrofobisitas sinkonin untuk meningkatkan penetrasi sinkonin ke follicle. Niosom merupakan vesikel ampifilik dengan struktur lapisan rangkap yang terbentuk dari hidrasi kombinasi surfaktan nonionik dan kolesterol yang mampu menurunkan hidrofobisitas sinkonin. Penelitian ini bertujuan untuk menentukan proses pembuatan niosom sinkonin yang optimum. Pembuatan niosom sinkonin diawali dengan menentukan temperatur gelasi (Tg) dari span 60 dengan Differential Scanning Calorimetry (DSC), kemudian dilanjutkan dengan optimasi proses meliputi: optimasi kecepatan rotavapor pembentukan film lapis tipis, temperatur hidrasi, kecepatan rotavapor hidrasi, waktu hidrasi, dan waktu sonikasi. Karakteristik vesikel niosom yang optimal meliputi: ukuran partikel dan indeks polidispersitas dengan menggunakan Particle Size Analized (PSA) serta efisiensi penjeratan sinkonin dengan menggunakan KCKT. Temperatur gelasi (Tg) span 60 45±2 oC, kecepatan rotavapor pembentukan film lapis tipis niosom 210 rpm, temperatur hidrasi 55±2 oC, kecepatan rotavapor hidrasi 210 rpm, waktu hidrasi 20 menit, waktu sonikasi suspensi niosom 1 menit. Ukuran vesikel yang diperoleh adalah 100–200 nm, indeks polidispersitas 0,2–0,4 dan efisiensi penjeratan niosom sinkonin 84,49±0,0025%. Proses pembuatan niosom sinkonin memiliki pengaruh besar terhadap hasil ukuran vesikel dan efisiensi penjeratan niosom sinkonin.

Abstract

Cassava peel is a natural material with cellulose content reaching 33.33%. In order to utilize cassava peel as a biodegradable polymer and renewable energy alternative, a delignification process is essential to separate cellulose from hemicellulose and lignin, which prevents the penetration of cellulose hydrolyzer. The delignification method chosen in this study was alkaline hydrogen peroxide (AHP). The AHP is based on the autoxidation of lignin using hydrogen peroxide (H2O2) in an alkaline environment. This method was chosen because it can damage the lignocellulosic structure with relatively low energy and is more selective for lignin. However, under certain conditions, AHP can trigger carbohydrate depolymerization, which decreases yield. Therefore, it is necessary to study the effect of H2O2 concentration, Solid/Liquid ratio (S/L) (w/v), and pH to evaluate the effectiveness of lignin removal in cassava peel. The concentration of H2O2 was varied into 1.5%, 3%, 4.5%, 6%, and 7.5%. The S/L ratio is varied to 1:3, 1:5, 1:7, 1:9,1:12. The pH of the solution was varied to 8, 9, 10, 11, and 12. The reaction temperature was maintained at 70-90 °C for 3 hours. The results showed that lignin could be reduced to 84.05% for 3 hours by using 6% H2O2, an S/L ratio of 1:5, and a pH of 11. The reaction carried out under these conditions can also increase the amount of cellulose from 33.33% to 49.00%.
