Abstract

Alga coklat (Sargassum sp.) merupakan tanaman yang mengandung senyawa flavonoid, alkaloid, tanin, dan terpenoid. Salah satu pemanfaatan alga coklat dalam ilmu farmasi adalah sebagai zat aktif dalam obat. Pada penelitian ini obat dibuat dalam bentuk sediaan tablet yang memiliki komposisi sebagai zat aktif utama obat dan bahan penghancur yaitu explotab (sodium starch glycolat). Penelitian ini bertujuan untuk membuat tablet dari ekstrak alga coklat (Sargassum sp.) dengan cara sokhletasi menggunakkan pelarut etanol 96%. Tablet dibuat menjadi tiga formula dengan varian konsentrasi explotab yang berbeda agar dapat mengetahui konsentrasi terbaik explotab sebagai bahan penghancur. Ketiga varian konsentrasi tersebut adalah 3%, 5%, dan 7%. Keuntungan bahan explotab sebagai bahan penghancur yaitu kekuatan pada aksi kapiler yang akan menarik cairan ke dalam tablet, sehingga dalam formulasi tablet bahan ini akan mengembang dan menjadikan tablet pecah dan hancur kemudian melarut. Metode yang digunakan pada pembuatan tablet adalah granulasi basah. Hasil uji evaluasi granul meliputi sifat alir, sudut istirahat dan kompresibilitas telah memenuhi syarat. Hasil uji evaluasi fisik tablet yang terdiri dari waktu hancur, kerapuhan, kekerasan, keseragaman bobot dan keseragaman ukuran, namun pada uji kekerasan tablet tidak memenuhi syarat. Konsentrasi explotab yang semakin tinggi maka waktu hancur yang dihasilkan semakin cepat dan kekerasan tablet semakin menurun. Kekerasan tablet berhubungan dengan kerapuhan, dimana semakin keras tablet maka kerapuhannya juga akan semakin kecil.

Abstract

Tanaman alga coklat (Sargassum sp.) dalam ilmu farmasi dapat dimanfaatkan sebagai salah satu zat aktif dalam obat. Obat yang dibuat dalam bentuk sediaan tablet ini memiliki komposisi alga coklat (Sargassum sp.) sebagai zat aktif utama obat dan bahan pengikat lainnya yang berupa polivinil pirolidon (PVP). Penelitian ini membahas lebih dalam mengenai keefektifan zat pengikat (PVP) dalam sediaan obat menggunakan metode granulasi basah. Ekstrak alga (Sargassum sp.)  yang pekat diperoleh dari ekstraksi dengan metode sokletasi menggunakan etanol 96%. Pembuatan tablet alga coklat (Sargassum sp.) diuji dengan zat pengikat (PVP) dalam 3 konsentrasi yang berbeda yaitu 3%, 5%, dan 9%. Sebelum memasuki tahapan pencetakan granul, sediaan obat harus melewati evaluasi sifat alir, sudut diam, dan kompresibilitas. Setelah itu dilakukan evaluasi sifat fisik tablet yang terdiri atas keseragaman bobot, keseragaman ukuran, kekerasan, waktu hancur, dan waktu paruh. Hasil yang didapatkan menunjukkan bahwa evaluasi uji sifat fisik granul dengan 3 variasi konsentrasi formula telah memenuhi syarat. Pada uji waktu hancur, kekerasan, keseragaman bobot, dan keseragaman ukuran tablet hanya konsentrasi PVP 5% saja yang memenuhi syarat dalam tablet obat alga coklat.

Abstract

Rhaphidophora pinnata, a plant traditionally recognized for its wound-healing properties, contains active compounds such as megastigmane glycosides and damascenone, known for their anti-inflammatory effects. To enhance efficacy and user comfort, this study focused on developing an R. pinnata leaf extract nanoparticle gel. Previous research from our group highlighted the significant wound-healing potential of a conventional R. pinnata gel. This present study aimed to evaluate the wound-healing efficacy of a novel R. pinnata nanoparticle gel in male Wistar rats, specifically investigating the impact of nanotechnology application. Nanoparticles were successfully formulated via the ionic gelation method, utilizing 0.250 g of R. pinnata extract, 0.1% chitosan, 0.2% sodium tripolyphosphate, and 0.5% Tween 80. Characterization revealed an average nanoparticle size of 165.70±42.76 nm with a zeta potential of 22.0±1.83 mV. The wound-healing efficacy was assessed across five treatment groups: a positive control (Bioplasenton®), a plain gel base (Formula 0), and nanoparticle gels at 0.5% (Formula I), 1% (Formula II), and 1.5% (Formula III) extract concentrations. Statistical analysis using one-way ANOVA (p <0.05) demonstrated a significant difference in incision wound healing across the groups. Formula III, containing 1.5% R. pinnata nanoparticle extract, exhibited the most superior wound-healing effect, achieving 100% inhibition by day 14, elevated hydroxyproline levels (59 µg/mL), and histologically confirmed excellent skin tissue repair. Formulas II and I followed in efficacy. These compelling findings underscore the significant potential of utilizing nanotechnology in the development of topical preparations for accelerated and effective wound healing.

Abstract

Gastroprotection refers to the effect of compounds that protect the gastric mucosa. Peperomia pellucida L. and Chromolaena odorata L. have demonstrated gastroprotective activities. Chromolaena odorata L., in particular, shows inhibition of gastric mucosal damage due to the presence of secondary metabolites such as flavonoids, phenolics, and tannins. Chitosan is a drug carrier that enhances drug bioavailability and allows pharmacological effects to be achieved at lower doses. This study aims to evaluate the gastroprotective activity of chitosan-based formulations containing Peperomia pellucida L. and Chromolaena odorata L. leaf extracts in rats. The contribution of this research lies in demonstrating the synergistic potential of medicinal plant extracts with chitosan as a delivery system, thereby providing a safer, more effective, and innovative therapeutic strategy for gastric ulcer management. Chitosan formulations containing Peperomia pellucida L. and Chromolaena odorata L. extracts were prepared and tested on male rats. The rats were divided into seven groups: Group I (normal control), Group II (negative control), Group III (positive control, treated with sucralfate), Groups IV and V (treated with chitosan-Chromolaena odorata formulations at doses of 100 and 200 mg/kg BW), and Groups VI and VII (treated with chitosan-Peperomia pellucida formulations at doses of 100 and 200 mg/kg BW). Treatments were administered orally for 14 days. On day 14, one hour after the final treatment, all groups except the normal group received oral absolute ethanol at a dose of 5 mL/kg BW to induce gastric injury. Gastric ulcer index, protection ratio, and histopathological changes were evaluated. The ulcer index values for the negative control, positive control, and treatment groups with doses of 100, 200, and 400 mg/kg BW were 4.89, 0.89, 0.33, 0.11, 1.00, and 0.78, respectively. The chitosan-based formulations containing Chromolaena odorata L. and Peperomia pellucida L. extracts demonstrated significant gastroprotective effects in ethanol-induced gastric injury in rats.

Abstract

The content of marine algae Sargassum hystrix includes polysaccharides (alginates), polyphenols, proteins, peptides, amino acids, lipids, minerals, and several vitamins. However, the use of natural ingredients has limitations, namely that it often fails in the clinical phase due to low bioavailability. One effort that can be done to overcome this problem is to formulate nanoparticles using chitosan polymer and sodium tri-polyphosphate. This study aims to formulate nanoparticles from the methanol extract of Sargassum hystrix with various chitosan concentration ratios. The methanol extract of Sargassum hystrix was obtained by extraction using the maceration method with 50% methanol as a solvent. The results of the extract were made colloidal nanoparticles using ionic gelation techniques using a variation of the methanol extract of Sargassum hystrix: chitosan: NaTPP: Tween 80, Formulation 1 (0.75 gram: 0.1% 18 mL: 0.1% 9 mL: 0.5% 3 mL); Formulation 2 (0.75 gram: 0.2% 18 mL: 0.2% 9 mL: 0.5% 3 mL); Formulation 3 (0.75 gram: 0.1% 18 mL: 0.2% 9 mL: 0.5% 3 mL); Formulation 4 (0.75 gram: 0.2% 18 mL: 0.1% 9 mL: 0.5% 3 mL). The nanoparticle colloids formed were characterized by particle size (nm), and the zeta potential (mV), Formula 1 (212.65 ± 45.32; -11.4 ± 5.65), Formula 2 (514.55 ± 56.35; -8.85 ± 1.34), Formula 3 (219.35 ± 43.76; -14.5 ± 1.83), Formula 4 (326.5 ± 3.39; -1.25 ± 17.88). All formulas show that they can form nanoparticle formulas between 1-1000 nm., But the preparation that will be more stable is formula 3 because it has a zeta potential that is close to +/- 30 mV.
