Abstract

Latar Belakang : Salah satu sumber antioksidan yang mudah ditemui terutama hampir di semua daerah di Provinsi NTT adalah daun kelor. Selain daun kelor, penggunaan jeruk nipis juga marak digunakan, akan tetapi kulit dari jeruk nipis kurang dimanfaatkjan, padahal jeruk nipis memiliki antioksidan dan juga dapat menekan rasa langu dari daun kelor. Dalam penyajiannya daun kelor dan kulit jeruk nipis dapat diolah menjadi minuman olahan yang praktis, salah satunya adalah teh celup. Tujuan dari penelitian ini adalah untuk mengetahui kandungan metebolit skunder khususnya flavonoid pada produk teh celup kombinasi daun kelor dan kulit jeruk nipis, parameter kualitas mutu dan IC50. Metode penelitian yang digunakan adalah metode penelitian eksperimen. Teknik pengumpulan data pada formulasi, uji kualitatif flavonoid, dan uji usia simpan dilakukan melalui uji praktikum. Sedangkan pada uji hedonik dilakukan dengan membagikan formulir kuisioner kepada para responden. Hasil penelitian menunjukkan teh positif mengandung flavonoid, kadar air diperoleh (1,04±0,68%)(b/b). Sedangkan pada hasil uji kadar abu, kadar abu diperoleh (7,34±0,17%)(b/b). Simpulan diperoleh hasil uji pada teh daun kelor kombinasi kulit jeruk nipis mengandung flavonoid, kadar air (1,04±0,68%)(b/b), kadar abu (7,34±0,17%)(b/b), dan 87,3 % dengan IC 50 2,94 dan tergolong sangat kuat Kata Kunci : Daun Kelor, Kulit Jeruk Nipis, Teh Celup

Abstract

Moringa (MO) leaves contain several chemical substances of high value, including vitamin C, flavonoids, phenolic compounds, carotenoids, tannins, and triterpenoids, among which one functions as an antioxidant. Previous research observed that MO leaves have already been developed into various formulations; unfortunately, these formulas could not completely obscure the aroma and taste problems that rendered MO leaves less acceptable to consumers. In this research, Moringa leaf powder (MLP) and red ginger (RG) are combined to cover the unpleasant taste and aroma of MO leaves. The purpose of this study assess the quality of three tea bag formulations, including their water content, ash content, hedonic and antioxidant activities, by quantitative tests; F0 (3 Gr of MLP), F1 (2.25 Gr of MLP, and 0.75 Gr of RG), and F2 (the amount of MLP and RG is equal to 1.5 Gr). This experimental study employs a completely randomized design, three special treatments, and three repetitions. Statistical analysis of quality test results and antioxidant activity uses One-Way ANOVA followed by a post hoc test utilizing the Least Significant Difference (LSD). The water content tests revealed that all three formulations qualified the Indonesian National Standard (SNI), ranging from 3.86% to 4.29%. Adding ginger did not influence the water content (p > 0.05). Otherwise, it increases the ash level from 8.65% to 9.98%. Based on the results of the hedonic test, the panelists preferred F0 over F1 and F2 concerning color by a score of 86%. In contrast, they preferred F2 regarding aroma and taste by a score of 82%. The addition of RG in F1 and F2 was significant to the preference level of panelists ('p <0.05). The IC50 value for the antioxidant activity test was highest for F2 at 59.31 ± 0.13 ppm. The addition of RG boosted the antioxidant activity of MO tea products considerably (sig <0.05). Consequently, developing MO tea products containing RG in F2 could be potentially produced as herbal tea beverages with antioxidant properties.

Abstract

The current development of antimalarial drug resistance encourages researchers to discover and develop novel antimalarials. One of its alternatives for antimalarial discovery is using medicinal plants remembering the success of artemisinin. Sterculia quardrifida R. Br. bark, locally name as faloak, is an endemic medicinal plant from East Nusa Tenggara that has been used traditionally to treat malaria. However, its antimalarial activity has not been investigated, yet. This study was aimed to evaluate the antiplasmodial activity of ethanolic extract of faloak bark against Plasmodium falciparum in vitro. Using FCR-3 P. falciparum strain, the ethanolic extract was evaluated on various concentration (1, 10, 50, and 100 μg/mL, respectively). The IC50 value was determined by the relationship between concentration and percentage of growth inhibition. The result showed that the percentage of inhibition of P. falciparum was concentration dependent, higher concentration resulting on higher percentage of inhibition with the IC50 42.399 ± 9.517 μg/mL. It can be concluded that the ethanolic extract of faloak bark have moderate antiplasmodial activity against P. falciparum in vitro.
