Pemanfaatan kosmetik  tradisional sebagai upaya pemeliharaan kecantikan  berupa kosmetik tradisional  oleh masyarakat terus meningkat. Tidak hanya racikan sendiri, produk kosmetik  tradisional saat inipun telah banyak beredar. Biji pepaya merupakan limbah dari pepaya yang tidak digunakan oleh masyarakat sehingga perlu diteliti kemanfaatannya dengan penghambatan terhadap enzim tyrosinase. Biji papaya (Carica papaya seed) mengandung senyawa flavonoid yaitu kaempferol dan quercetin. Penelitian ini bertujuan untuk mendapatkan hasil penghambatan enzim tyrosinase dar biji papaya yang akan membuat kulit menjadi lebih putih. Pengujian ini menggunakan tiga jenis ekstrak biji pepaya dengan variasi cairan penyari (methanol, n-Heksane, air) dan dilakukan pengujian terhadap penghambatan enzim tyrosinase. Dipoeroleh penghambatan IC50 177 ppm. Dari hasil penelitian yang telah dilakukan maka disimpulkan bahwa ekstrak biji papaya (Carica papaya) dengan perbedaan cairan penyari memiliki efektivitas sebagai krim pemutih.

The future of fossil fuel sources of energy has necessitated the need to search for renewable alternatives. Thus, Carica papaya seed oil (CPSO) was employed as feedstock for the production of biodiesel by methanolysis. The seed was obtained locally, dried, and extracted with n-hexane. The CPSO was analyzed for specific gravity, viscosity, iodine value, and saponification value, among others using standard methods. The oil was transesterified by two-stage catalysis with oil to methanol mole ratio of 1 : 9. The biodiesel produced was subjected to standard fuel tests. The seed has an oil yield of 31.2% which is commercially viable. The kinematic viscosity of the oil at 313 K was 27.4 mm2s−1 while that of Carica papaya oil methylester (CPOME) was reduced to 3.57 mm2s−1 and the specific gravity was 0.84 comparable with other seed-oil biodiesels and number 2 diesel. Other oil properties were compared favourably with seed oils already documented for biodiesel synthesis. CPOME’s cloud and pour points were 275 K and 274 K, respectively, and relatively higher than other biodiesels and number 2 diesel. CPOME exhibits moderate corrosion of copper strip. The methanolysis improved the fuel properties of the CPOME similar to other biodiesels. CPSO therefore exhibits a potential for biodiesel production.

Aims: Rifampicin one of the most commonly used front-line drugs in antituberculosis therapy, has been known to be hepatotoxic. The oxidative stress that is formed in the mitochondria due to rifampicin and isoniazid causes an imbalance in lipid metabolism. This study aims to determine the effect of lowering total cholesterol, triglyceride, and LDL levels and increasing HDL levels of papaya seed ethanol extract in rats induced by rifampin and isoniazid. Study design: This study is experimental study. Methodology: This study was divided into 9 groups including normal group, negative group 1, 2, 3, positive 1, 2, treatment group I (EECP 100 mg/kgbw), treatment group II (EECP 300 mg/kgbw), and treatment group III (EECP 500 mg/kgbw). Rifampicin (50 mg/kgbw), isoniazid (50 mg/kgbw), and EECP were given 28 days, on day 29 rats were dissected and blood was taken and the total cholesterol, triglyceride, LDL and HDL levels were measured. Results: The results showed that the ethanol extract of papaya seeds at a dose of 100 mg / kgbb, 300 mg / kgbb, and 500 mg / kgbw could reduce levels of total cholesterol, triglycerides, LDL and increase HDL levels. The dose of 500 mg / kgbw was not statistically significant (P> 0.05) with the normal group. Conclusion: Ethanol extract of Carica papaya has a potential effect of preventing the destruction of lipid metabolism effect by reducing the LDL, Trygliseride, Cholesterol Total, and increasing the level of HDL.
