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

In conservation, identification of tarsier species based on morphological and molecular characters isrequired. However, to date the identification of animals is simply based on their morphological characterand vocalizations, while in fact it is difficult to identify each species of Tarsius sp morphologicaly.  Thepurpose of this study is to obtain genetic markers that can be used to identify Tarsius sp on ND6 mitochondrialgenes and reveal affiliations and phylogenetic relationships Tarsius sp. with other members of primates.Samples were obtained from several original habitats of Tarsius sp. Three samples were taken from NorthSulawesi, one sample was collected from Central Sulawesi, three samples from Kalimantan  and threesamples from South Sumatra. The isolated DNA is then used as a template for amplification of DNAfragments by PCR. Amplicon (PCR product) obtained 566 bp and 629 bp. Nucleotide sequencing resultsshows 513 nucleotides, the smallest genetic distances of 0%, the highest of 30.2% and average of 16.3%.Nucleotide and amino acid sequences of ND6 can be used as genetic markers to differenciate T. spectrum,T. dianae and  T. bancanus but they fail to function as genetic markers to distinguish  T. bancanus ofKalimantan and Sumatra origin.
