Convective drying of papaya seeds (Carica papaya L.) and optimization of oil extraction

Papaya is the most beneficial fruit for human health. In addition to the fruit that can be consumed, it turns out papaya seeds can also be used. In addition to the seeds used to be planted as well as only being waste, oil can also be obtained from papaya seeds. One method for obtaining papaya seed oil is a method of extracting heat (requires installation in the process), in general the notion of reflux is extraction with a solvent at its boiling temperature point, for a certain time and the amount of solvent adjusted to air temperature. In this research, papaya seed extraction was carried out, percent yield analysis was carried out, and heavy type analysis of papaya seed oil extraction was carried out. The purpose of this study was to study the variation in extraction time of papaya seeds with solvents on the yield of oil produced. This research was carried out by reacting papaya seeds with hexane solvents at 65 ℃. Where the weight of papaya seeds is 50 gr, and the volume of solvents varied by 300 ml, 400 ml, and 500 ml and the reaction time is 120 minutes, 150 minutes, and 180 minutes. The results showed that the largest papaya seed oil was 34.2% at a volume of 500 ml solvent for 180 minutes and a high density of 0.87 gr / ml at a volume of 500 ml solvent for 180 minutes.Keywords: Extraction, hexane, papaya seed oil, reflux

ABSTRAKTumbuhan pepaya (carica papaya L) merupakan tumbuhan tropis yang banyak terdapat di Indonesia. Tumbuhan ini mempunyai banyak manfaatnya mulai dari buah, biji, hingga daunnya. Penelitian pendahuluan menyebutkan buah pepaya mengandung alkaloid dan flavonoid yang berkhasiat sebagai antikanker. Senyawa BenzylIsothiocyanat diketahui banyak terdapat pada biji dan buah pepaya yang sudah matang. Kandungan BenzylIsothiocyanat mempunyai khasiat sebagai antikanker. Pemanfaatan limbah biji pepaya pada penelitian ini untuk membuktikan aktivitas Benzyl-Isothiacyanat yang berkhasiat sebagai antikanker. Penelitian ini merupakan penelitian pendahuluan untuk menganalisis aktivitas antikanker dari Ekstrak kental biji pepaya dengan menggunakan metode BSLT. Konsentrasi ekstrak kentak yang digunakan yaitu 100 ppm, 200 ppm dan 300 ppm masing-masing diujikan pada 10 larva udang dalam air laut. Diperoleh hasil rata-rata kematian pada konsentrasi 100 ppm adalah 4,3, 200 ppm adalah 5,3 dan 300 ppm adalah 6,7. Hasil regresi linearitas menunjukkan aktivitas antikaker pada uji BSLT dari Ekstrak kental biji pepaya dengan LC50 sebesar 163,89 ppm. Dengan demikian ekstrak kental biji pepaya tersebut berpotensi untuk dikembangkan sebagai bahan antikanker alamiKata kunci: Aktivitas antikanker, Carica papaya, metode BSLT.ABSTRACTPapaya plant (carica papaya L) is a tropical plant that is widely found in Indonesian. This plant has many benefits ranging from fruit, seeds, to leaves. Preliminary research says papaya fruit contains alkaloids andflavonoids which are efficacious as anticancer. Benzyl-Isothiocyanat compounds are known to be widely found in ripe papaya seeds and fruit. The content of Benzyl-Isothiocyanat has properties as an anticancer. The use of papaya seed waste in this study is to prove the activity of Benzyl-Isothiacyanat which is efficacious as an anticancer. This research is a preliminary study to analyze the anticancer activity of thick papaya seeds using the BSLT method. The concentrations of used fart extracts were 100 ppm, 200 ppm and 300 ppm each tested on 10 shrimp larvae in seawater. The results of the average mortality at concentrations of 100 ppm were 4.3, 200 ppm were 5.3 and 300 ppm was 6.7. The linearity regression results showed the anticaker activity in the BSLT test from the thick extract of papaya seeds with LC50 of 163.89 ppm. Thus the thick extract of papaya seeds has the potential to be developed as a natural anticancer material.Key Words : Anticancer activity, BSLT method, Carica papaya.

Background: Nephrotoxicity is characterized by raised serum urea and creatinine levels and kidneys being one of the primary organs of drug concentration and excretion are vulnerable to many widely used marketed drugs, including anti-cancer drugs, antibiotics, immunosuppressants, and radio contrast agents, are nephrotoxic. Aim: To determine the nephroprotective effect of ethanolic extract of Carica papaya seeds in Aminoglycoside induced acute nephrotoxicity. Study design: Quasi Experimental study. Methodology: Thirty Sprague Dawley rats were sub divided into 3 groups i.e., I, II and III with 10 rats in each group. Group II and III were administered Aminoglycoside drug; Gentamycin in 80 mg/kg) via intraperitoneal route once daily for 5 consecutive days to induce acute nephrotoxicity. At day 6, nephrotoxicity was confirmed by measuring serum urea and creatinine. Ethanolic extract of Carica papaya seeds (1000 mg/kg) was started once daily through oral route in group III for 5 consecutive days to see the nephroprotective effects of seed extract after causing acute kidney injury. All animals were given standard diet pellets manufactured at NIH. Results: Mean serum urea and creatinine for Group I (Control Group) at day 0 were 24.90 mg/dL ± 1.633 and .750 mg/dL ± .0619 respectively. Mean serum urea and creatinine for Group II (Disease Control Group) was 81.00 mg/dL ± 1.247 and 1.980mg/dL ± .0467 at day 6th. This suggested induction of nephrotoxicity by Gentamycin. Mean serum urea and creatinine for Group III (Ethanolic Extract Treated Group) at 11 day was 72.40mg/dL± .991 and 1.680 mg/dL± .0467 after 5 days treatment with ethanolic extract of Carica papaya seeds. Conclusion: We concluded that ethanolic extract of Carica papaya seeds has significant nephroprotective effects on Aminoglycoside induced acute nephrotoxicity in rats.

Tetrazolium Test

Germination test for papaya seeds demands thirty days to obtain the results, which is a long period for decision-making. Thus, rapid tests become essential tools to evaluate seed viability, and the tetrazolium test is an alternative for this purpose. Hence, this study aimed to establish the adequate procedure to apply this test, in order to reduce the time of evaluation of papaya seeds. For that, four tetrazolium solution concentrations (0.05, 0.1, 0.5 and 1%) and three staining times (3, 6 and 9 hours) were tested at temperatures of 35 and 40 ºC. The experimental design was completely randomized in 4 × 3 + 1 factorial scheme (concentrations × staining times + one control = germination test). It was found that the tetrazolium test allows to evaluate the physiological quality of papaya seeds, thus reducing the time for decision-making. For the test, we recommend using the concentrations of 0.1% for 9 hours or 1% for 6 hours of staining, at temperature of 40 ºC.
