Abstract

Teh hijau diketahui mengandung senyawa polifenol, yang sangat mendukung aktivitas antioksidannya. Aktivitas tersebut membuat ekstrak teh hijau bisa dimanfaatkan secara oral ataupun topikal. Pada penggunaan topikal, perlu dilakukan upaya untuk meningkatkan kemampuan penetrasi perkutan, salah satunya dengan pengembangan sediaan nanoemulsi. Penelitian ini bertujuan untuk mengembangkan sediaan nanoemulsi antioksidan mengandung ekstrak teh hijau dengan minyak calendula sebagai fase minyak dengan karakteristik yang baik. Teh hijau diekstraksi dengan metode refluks menggunakan etanol 96% sebagai  pelarut. Pengujian aktivitas antioksidan ekstrak dilakukan dengan metode peredaman DPPH. Ekstrak selanjutnya dikembangkan menjadi sediaan nanoemulsi dengan menggunakan surfaktan tween 80 dan kosurfaktan PEG400. Hasil penelitian menunjukkan, ekstrak etanol teh hijau memiliki aktivitas antioksidan yang sangat kuat dengan nilai IC50 2,14 ± 0,01 ppm. Ekstrak etanol berhasil dikembangkan menjadi sediaan nanoemulsi dengan menggunakan minyak calendula sebagai fase minyak, pada perbandingan minyak dan Smix (campuran surfaktan dan kosurfaktan) 1:12  dan perbandingan surfaktan dan kosurfaktan 2:1. Sediaan nanoemulsi teh hijau memiliki karakteristik fisik yang baik, ditandai dengan  penampilan yang transparan,  ukuran globul  15,97  ± 0,49 nm dan nilai indeks polidipersitas  0,29 ± 0,01. Sediaan nanoemulsi juga stabil merujuk pada pengujian heating cooling, sentrifugasi, dan  freeze thaw. Telah berhasil dikembangkan sediaan nanoemulsi mengandung minyak calendula dan ekstrak teh hijau dengan karakteristik dan stabilitas fisik yang baik.

Limbah kulit buah cokelat diketahui mengandung berbagai senyawa aktif seperti polifenol dan flavonoid sehingga berpotensi memiliki aktivitas inhibitor tirosinase. Untuk meningkatkan kemampuan penetrasi ekstrak pada penghantaran topikal akan dikembangkan menjadi sediaan nanoemulsi. Tujuan dari penelitian ini untuk menguji aktivitas inhibitor tirosinase ekstrak kulit buah cokelat dan memformulasikannya menjadi sediaan nanoemulsi yang memiliki sifat fisik yang baik. Simplisia diekstraksi dengan metode maserasi menggunakan etanol 70% dan selanjutnya diuji aktivitas inhibitor tirosinasenya dengan metode dopakrom berbasis colorimetric enzymatic assay. Sediaan nanoemulsi ekstrak kulit buah cokelat dibuat dengan menggunakan minyak biji anggur, tween 80 sebagai surfaktan, dan gliserin sebagai kosurfaktan untuk selanjutnya dikarakterisasi secara fisik. Hasil uji menunjukkan ekstrak kulit buah cokelat memiliki aktivitas inhibitor tirosinase dengan nilai IC50 199,98 ppm. Sediaan nanoemulsi mengandung ekstrak kulit buah cokelat penampilan fisik yang jernih dan homogen, pH 6,21±0,02, viskositas 1070 ± 24,5 cps, sifat alir Newtonian, dengan ukuran globul 108 ±15 nm. Sediaan nanoemulsi memiliki stabilitas fisik yang baik berdasarkan uji sentrifugasi, heating cooling, dan freeze thaw. Disimpulkan bahwa ekstrak kulit buah cokelat terbukti memiliki aktivits inhibitor tyrosinase dan telah berhasil diformulasikan menjadi sediaan nanoemulsi dengan sifat fisik dan stabilitas yang baik.

Abstract

Background: The incidence and mortality of cancer are rapidly growing worldwide. Modification on drug delivery systems based on nanotechnology was applied to improve the effectiveness and safety of treatment. Nanoencapsulation, a part of nanotechnology, was known can be involved in cytotoxic agents. Objective: This research was conducted to determine the type of polymers for nanoencapsulation of cytotoxic agents and analyze the effect of nanoencapsulation on the cytotoxic activity. Methods: The study was performed by systematic literature review using selected articles from reputable databases that meet the inclusion and exclusion criteria. Results: The results show that many cytotoxic agents have been developed in nanocapsules systems due to their low water solubility, chemical instability, and low bioavailability. The nanoencapsulation process was carried out using synthetic or natural polymers such as polylactic-co-glycolic acid (PLGA), PEGylated PLGA, polycaprolactone (PCL), chitosan-sodium tripolyphosphate, chitosan-sodium alginate, heparin-poly(l-lysine), and polymethyl methacrylate (PMMA). Those polymers are widely used for nanoencapsulation related to their biocompatible, biodegradable, non-toxic, and providing the desired coating properties. The nanoencapsulation on cytotoxic agents significantly increases the in vitro cytotoxicity, marked by the decrease of IC50 value in the range 1.4-15.4 folds compared to pure drugs. The increase in cytotoxicity could be caused by particle size reduction, modification of particle surface properties, and enhancement of drug stability. Conclusion: It can be concluded that nanoencapsulation can be applied for cytotoxic agents to increase their activity using the appropriate coating polymer.

Abstract

White tea and pomegranate seed oil are known to contain many bioactive compounds that make them potentially have antioxidant and photoprotective activities. This study aimed to examine the antioxidant and photoprotective activities of white tea leaf extract and develop it in an emulgel dosage form. White tea is extracted with 70% ethanol at 600C. The extracts were tested for antioxidant activity by the DPPH method and for photoprotective activity by the Mansur method. White tea extract was developed into an emulgel with pomegranate seed oil as the oil phase, stearic acid and TEA as emulsifiers, and viscolam mac 10 as a gelling agent. The results showed that the ethanol extract of white tea had a very strong antioxidant activity with an IC50 value of 10.80 ± 0.75 ppm. White tea ethanol extract also has photoprotective activity with an SPF value of 12.35 ± 0.63, %Te value of 2.13 ± 0.01 %, and %Tp value of 45.13 ± 0.08 % (ultra protection category). White tea extract has been successfully developed into an emulgel preparation with good characteristics and stability in terms of organoleptic, pH, viscosity, spreadability, and rheological behavior. White tea emulgel are stable based on centrifugation and freeze-thaw tests.

Abstract

Diabetic foot infection (DFI) is a common complication of diabetes, most frequently caused by Staphylococcus aureus. Green tea contains antibacterial compounds and may serve as a potential supportive therapy for DFI. This study aimed to develop a spray gel formulation containing green tea ethanol extract and evaluate its antibacterial activity against S. aureus. The extract was obtained using 96% ethanol through the reflux method and subsequently tested for antibacterial activity using the agar well diffusion method. The extract was incorporated into a spray gel formulation with Viscolam MAC 10 as the gelling agent. The resulting spray gels were evaluated for their physical properties and antibacterial activity. Green tea extract demonstrated antibacterial activity against S. aureus with a minimum inhibitory concentration (MIC) of 0.1%. Furthermore, the ethanol extract was successfully formulated into a spray gel using 5% Viscolam MAC 10, meeting quality requirements in terms of organoleptic properties, pH, viscosity, spray pattern, spray weight, drying time, and adhesion time. Formulations containing 0.75% and 1% GTE exhibited potent antibacterial activity against S. aureus. In conclusion, a green tea–based spray gel formulation with good physical characteristics and potent antibacterial activity has been successfully developed.
