Abstract

Herbal yang berperan sebagai antioksidan dan antikanker diantaranya temulawak. Penelitian pengaruh ekstrak temulawak terhadap hematologi tikus pada pengujian keamanan subkronis dilakukan pada penelitian ini.  Parameter hematologi yang ditentukan adalah nilai hemoglobin, hematokrit, dan jumlah leukosit. Hewan coba yang digunakan adalah tikus jantan dan betina dari galur Sprague Dawley. Herbal yang diberikan sebagai pengobatan adalah ekstrak etanol 70% temulawak yang diberikan sebanyak 5 hari dalam seminggu selama 28 hari dengan dosis bertingkat mulai dari 45 mg/Kg BB hingga 5.625 mg/kg BB. Hasil yang diperoleh adalah perlakuan terakhir tidak ada tikus yang mati. Berdasarkan pengukuran diperoleh nilai hemoglobin antara 12,57-17,97 g/dL, nilai hematokrit antara 31,77-51,57%, dan jumlah leukosit antara 5,01-23.22x103 sel/μL (normal). Kesimpulan dari penelitian ini adalah bahwa dosis lebih besar dari 5625 mg/kg BB merupakan nilai LD50 untuk ekstrak etanol 70% temulawak. Pemberian ekstrak etanol 70% temulawak hingga dosis 5.625 mg/kg BB selama 28 hari pada tikus jantan dan betina memberikan efek penurunan terhadap nilai hemoglobin, hematokrit, dan leukosit, namun nilainya masih dalam batas normal. Tidak ada perbedaan nyata antara tikus jantan dan betina pada hasil pengukuran nilai hemoglobin, hematokrit, dan leukosit. Kata Kunci: Dosis, Hematologi, Subkronis, Temulawak, Tikus  Herbs that act as antioxidants and anticancer include temulawak. Research on the effect of temulawak extract on rat hematology in subchronic safety testing was carried out in this study. The determined hematological parameters were the value of hemoglobin, hematocrit and the number of leukocytes. The experimental animals used were male and female rats from the Sprague Dawley strain. The herbs given as treatment were an ethanolic extract of 70% temulawak which was given 5 days a week for 28 days with a graduated dose ranging from 45 mg/Kg BW to 5625 mg/kg BW. The results obtained are the last treatment no rat died. Based on the measurement of hemoglobin values obtained between 12.57 to 17.97 g/dL, hematocrit values obtained between 31.77 to 51.57% and leukocyte counts obtained between 5.01 to 23.22x103 cells/μL were still in the normal range. The conclusion of this study is that a dose greater than 5,625 mg/kg BW is the LD50 value for the ethanol extract of 70% temulawak. Giving 70% ethanol extract of temulawak until a dose of 5,625 mg/kg BW for 28 days to male and female rats had a decreasing effect on hemoglobin, hematocrit, and leukocyte values, but the values were still within normal limits. There is no significant difference between male and female rats in the measurement results of hemoglobin, hematocrit, and leukocyte values.

Abstract

Alzheimer adalah salah satu penyakit neurodegeneratif kronis dan menjadi penyakit yang sering dialami oleh orang lanjut usia. Perubahan yang terjadi dari penyakit Alzheimer, yakni penurunan fungsi kognitif, memori, dan perubahan perilaku secara permanen. Senyawa aktif pada daun sirih merah memiliki kesamaan kandungan dengan daun sirih hijau untuk menghambat butirilkolinesterase (BChE). Butirilkolinesterase adalah salah satu enzim yang berperan dalam penanganan penyakit Alzheimer dikaitkan dengan terbentuknya Alzheimer, yakni hipotesis kolinergik. Penelitian dilakukan menguji daya inhibisi senyawa aktif yang terkandung dalam daun sirih merah terhadap aktivitas butirilkolinesterase melalui pendekatan simulasi penambatan molekuler. Penelitian menggunakan dua metode, yakni penggabungan penapisan virtual dan penambatan molekuler sebagai tahapan awal pengembangan daun sirih merah terhadap aktivitas penghambatan butirilkolinesterase. Hasil dalam penelitian diperoleh, daya inhibisi terbaik ditemukan pada 1,2,3,4,5,6,7-heptazacycloicosane sebesar 0,4888 µM dan energi bebas pengikatan sebesar -8,6 kkal∙mol-1. Residu yang berperan dalam menghambat butirilkolinesterase, yakni pada pengikatan substrat oleh ligan uji, yakni Tyr-332 dan Trp-82. Hasil penelitian ini dapat dijadikan sebagai sumber referensi dalam menemukan alternatif pengobatan penyakit Alzheimer. Molecular Docking of the Active Compound of Red Betel (Piper crocatum) on Butyrylcholinesterase as an Antialzheimer's Candidate. Alzheimer's is a chronic neurodegenerative disease often experienced by the elderly. Changes that occur from Alzheimer's disease such as permanent decline in cognitive function, memory, and behavioral changes. The active compounds in red betel leaves have similar contents with green betel leaves to inhibit butyrylcholinesterase (BChE). Butyrylcholinesterase is an enzyme that may play an important role in the treatment of Alzheimer's disease associated with the formation of Alzheimer's, the cholinergic hypothesis. The study tested the inhibition power of the active compounds contained in red betel leaves against the activity of butyrylcholinesterase through a molecular docking simulation approach. The method in the study used the merger of virtual screening and molecular docking as the initial stage for the development of red betel leaves against the inhibitory activity of butyrylcholinesterase. The result in the study found the best inhibitiron power was found at 1,2,3,4,5,6,7-heptazacycloicosane of 0.4888 µM and binding free energy of -8.6 kkal∙mol-1. The residues that play a role in the inhibition of butyrylcholinesterase on substrate binding by test ligands were Tyr-332 and Trp-82. The research result can be used as a reference in finding alternative treatments for Alzheimer's disease.

Abstract. Andrianto D, Husnawati, Hermita S, Haryanti S. 2020. Classification of betel leaves (Piper betle) from 15 ethnics in eastern Indonesia based on phytochemicals fingerprint analysis. Biodiversitas 21: 252-257. Betel (Piper betle Linn), also called Golden Heart of Nature, is often used as traditional medicine. Nonetheless, betel plants originated from different places contains different phytochemicals profile, resulting in different utilization across ethnics. The research aimed to classify betel leaves from eastern Indonesia origins based on phytochemical profiles. In this study, the phytochemical profiles of 69 betel leave samples from 15 ethnics in eastern Indonesia were obtained using High-Performance Liquid Chromatography (HPLC) fingerprint analysis. This data was then used to classify the betel leaves samples using Principal Component Analysis (PCA). The results of the analysis show that the betel leaves from Eastern Indonesia can be divided into three clusters. Cluster 1 consisted of betel leaves originated from two ethnics, namely Komoro and Greri, from Papua, while Cluster 2 consisted of those originated of two ethnics, namely Sumber Baba and Demta, both were also from Papua. Cluster 3 consisted of betel leaves originated 11 ethnics, namely Asilulu (Maluku), Balesang (Central Sulawesi), Bungku (Central Sulawesi), Mulong Kuni (Central Sulawesi), Saluan (Central Sulawesi), Tialo (Central Sulawesi), Tolage (Central Sulawesi), Gebe (North Maluku), Makian (North Maluku), Mey Brat (West Papua) and Waigeo (West Papua). The location of P. betle plantation in this research accounts for clusterization of samples, Papua island give the highest biodiversity because we can find all the three cluster in Papua island.
