Abstract

Indonesia is rich in flora potentially used for herbal medication. One of the potential herbal is koro benguk (Mucuna pruriens) beans, where in Central Java and Yogyakarta is proccessed into tempe (fermented mucuna beans) for daily human consumption. Koro benguk has high level of L-3,4-dihydroxyphenylalanine (L-DOPA) which has a potential neuroprotective effect on Parkinson’s disease. The aim of this study was to investigate the L-DOPA content in fresh beans, cooked and fermented of koro benguk beans. The investigation were done in fresh mucuna beans, white color (BR D) and black color (BR A) beans originated from Wonogiri, Central Java, and fresh, white color (KP C), cooked, and fermented beans collected from Kulon Progo, Yogyakarta. The samples were extracted using ethanol and n-propanol solutions and were analyzed using high-performance liquid chromatography (HPLC) technique. The results show that the highest L-DOPA level (8,56%) was found in fresh white koro benguk beans from Wonogiri extracted using ethanol. The lowest L-DOPA level (0,016%) was found in fermented beans that extracted using n-propanol. Extraction using ethanol yield a higher L-DOPA level as compared to that of using n-propanol. In brief, all of the samples starting from fresh bean, cooked, and fermented koro benguk beans contain L-DOPA, with highest L-DOPA level was found in the white fresh koro benguk beans, from Wonogiri, Central Java. The lowest ingredient L-DOPA level was found in the fermented beans from Kulon Progo, Yogyakarta. ABSTRAK Indonesia sangat kaya dengan keanekaragaman flora yang potensial untuk terapi herbal, salah satunya tanaman koro benguk (Mucuna pruriens) yang bijinya bisa diolah menjadi tempe sebagai konsumsi harian masyarakat di sekitar Yogyakarta dan Jawa Tengah. Biji koro benguk diketahui mengandung L-3,4-dihydroxyphenylalanine (L-DOPA) tinggi dan berpotensi menjadi agen neuroprotektor pada penyakit Parkinson. Penelitian ini bertujuan untuk menguji kandungan L-DOPA mulai dari biji koro benguk segar, rebus, dan bahan olahannya yaitu tempe benguk. Uji dilakukan pada biji koro benguk mentah kulit berwarna putih (BR D) dan hitam (BR A) asal Wonogiri, Jawa Tengah, serta biji koro benguk mentah kulit berwarna putih (KP C), biji koro benguk yang sudah direbus dua kali, dan tempe benguk asal Kulon Progo, Yogyakarta. Sampel diekstraksi menggunakan pelarut etanol dan n-propanol, kemudian dianalisis dengan teknik high-performance liquid chromatography (HPLC) untuk melihat kadar kandungan L-DOPA-nya. Hasil penelitian menunjukkan, kadar L-DOPA tertinggi (8,56%) ditemukan pada biji koro benguk mentah dengan warna kulit putih asal Wonogiri yang diekstraksi menggunakan pelarut etanol, sedangkan kadar L-DOPA terendah (0,016%) ditemukan pada sediaan tempe yang diekstraksi dengan n-propanol asal Kulon Progo. Secara umum, ekstraksi menggunakan pelarut etanol memberikan hasil kadar L-DOPA yang lebih tinggi dibandingkan dengan pelarut n-propanol. Semua ekstraksi sampel, mulai biji koro benguk segar, rebus sampai bentuk tempenya mengandung L-DOPA, dengan kadar tertinggi terdapat pada biji koro benguk segar berkulit putih asal Wonogiri, Jawa Tengah yang diekstraksi menggunakan etanol, sedangkan kadar terendah dijumpai pada tempe benguk dari Kulon Progo, Yogyakarta yang diekstraksi menggunakan n-propanol.

Abstract

Cuscus is marsupial’s animal (Phalageridae) which has limited spread in eastern Indonesia (Sulawesi,Maluku, Papua), Australia and Papua New Guinea. The ex-situ and in-situ conservation of cuscus undercaptivating condition is an alternative solution to protect cuscus from extinction. This study aimed todetermine nucleotide sequence and genetic markers on 12Sr RNA gene with sequencing method of eachspecies on three islands. Whole genome DNA was extracted from 17 samples of cuscus obtained fromdifferent habitats, Sulawesi (2 individual), Maluku (7 individual), and Papua (8 individual) according tothe protocol of Qiamp DNA Blood Mini Kit (Qiagen), and then it was used as template for amplificationof 12Sr RNA gene by using PCR. PCR product were then purified using column chromatography and wereused as template for sequencing reaction. Result sequencing of 12Sr RNA gene were analyzed usingMEGA program version 6. PCR product gives a result nucleotida of 958 bp according to databasegenebank, sequencing product gives result nucleotida of 896 bp and found of 105 different nucleotide sites.Filogram based on nucleotide sequences 12SrRNA gene from Sulawesi cuscus is Ailurops ursinus whereasthe cuscus from Papua and Maluku is Phalanger sp. and Spilocuscus maculatus species. Thirteen nucleotidasites were found, sites no 67 (A/G), 89 (G/C), 137 (T/C), 285 (G/A), 468 (T/C), 595 (T/C, 598 (T/C), 647 (T/C),654 (G/A), 665 (T/C), 769 (C/T), 874 (C/T), and 876 (A/G) which can be used as genetic marker betweenPhalanger genera from Papua and Maluku, and three nucleotida sites (sites no 127 (G/A), 481 (C/T), and885 (T/C) can be used as genetic marker between Spilocuscus genera from Papua and Maluku.

Abstract

In a conservation effort, the identification of Tarsier species, on the bases of the morphological andmolecular characteristic is necessary. Up to now, the identification of the animals were based on themorphology and vocalizations, which is extremely difficult to identify each, tarsier species. The objective ofthis research was to study the genetic diversity on ATP6 gene of Tarsius sp. Based on sequencing of PCRproduct using primer ATP6F and ATP6R with 681 nts. PCR product. The sequence of ATP6 fragmentswere aligned with other primates from Gene bank with aid of software Clustal W, and were analyzed usingMEGA program version 4.0. Three different nucleotide sites were found (nucleotide no. 288, 321 and 367).The genetic distance based on nucleotide ATP6 sequence calculated using Kimura 2-parameter modelindicated that the smallest genetic distance 0%, biggest 0.8% and average 0, 2%. The phylogenetic treeusing neighbor joining method based on the sequence of nucleotide ATP6 gene could not be used todifferentiate among T. Dianae (from Central Sulawesi), T. Spectrum (from North Sulawesi), T. bancanus(from lampung, South Sumatera) and T.bancanus from West Kalimantan.
