Abstract

Rhizopora stylosa, yang dikenal sebagai bakau merah, merupakan salah satu jenis tanaman bakau yang dapat ditemukan melimpah di Indonesia. Masyarakat secara tradisional memanfaatkan tanaman ini sebagai sumber pewarna dan obat tradisional. R. stylosa juga terbukti mengandung zat bioaktif dan metabolit sekunder yang memiliki nilai penting bagi manusia dan organisme lain. Tujuan dari penelitian ini adalah untuk menguji tingkat sitotoksisitas dan genotoksisitas senyawa metabolit sekunder dalam fraksi-fraksi ekstrak etanol R. stylosa terhadap akar dan kromosom tanaman bawang Allium cepa. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL), melibatkan sebelas fraksi dengan konsentrasi seragam (125 ppm), serta kontrol negatif berupa larutan akuades dan kontrol positif berupa larutan EMS, dengan dilakukan sebanyak 3 kali pengulangan. Parameter yang diobservasi meliputi indeks mitosis, pertumbuhan akar bawang, dan aberasi kromosom. Hasil pengamatan dianalisis menggunakan ANOVA Ft(α.05) dan uji lanjutan Duncan Ft (α.05). Hasil pengujian sebelas fraksi dengan konsentrasi 125 ppm menunjukkan penurunan nilai indeks mitosis yang bervariasi, serta terdeteksi adanya aberasi kromosom dengan frekuensi yang beragam. Meskipun demikian, sebelas fraksi tidak menunjukkan sifat subletal maupun letal terhadap indeks mitosis. Jenis aberasi kromosom yang teramati meliputi anaphase spindle break, ball metaphase, break, bridge, c-mitosis, delayed anaphase, diagonal anaphase, disorder of chromosome kinetic, double bridge, double lesion, fragment, giant cell showing polyploidy, laggard, micronucleus, nuclear erosion, nuclear extrusion, ring, star, stickiness, dan vagrant. Rhizopora stylosa (red mangrove) is one species of mangrove that is easily found in large quantities in Indonesia. This plant is widely used traditionally by the community as dyes and herbal medicine. R. stylosa is also known to contain valuable bioactive substances and secondary metabolites for humans and other organisms. This study aims to examine the cytotoxicity and genotoxicity of secondary metabolite compounds from fractions of R. stylosa ethanolic leaf extract on the roots and chromosomes of A. cepa onions. The study was conducted using an experimental method with a Completely Randomized Design (CRD), the treatment of eleven fractions with one 125 ppm for all fractions, and negative control of distilled water solution and positive control of EMS solution, with 3 repetitions for each treatment. The parameters observed were mitotic index, onion root growth and chromosomal aberration. The observations were analyzed with ANAVA Ft (α.05) and followed by Duncan Ft test (α.05). The results of eleven fractions with a concentration of 125 ppm showed a decrease in the value of various mitotic indices and the discovery of chromosome aberrations with varying frequencies. However, eleven fractions did not show a sub-lethal or lethal effect onf the mitotic index. Among the types of chromosomal aberrations observed were anaphase spindle break, ball metaphase, break, bridge, c-mitosis, delayed anaphase, diagonal anaphase, disorder of chromosome kinetic, double bridge, double lesion, fragment, giant cell showing polyploidy, laggard, micronucleus, nuclear erosion, nuclear extrusion, ring, star, stickiness, and vagrant.
乙醇提取物中提取的乙醇和根瘤性的影响。用于alium cepa的根上的细胞分裂和染色体。
被称为红红树林的根瘤菌是印度尼西亚发现的丰富的红树林品种之一。传统上,人们利用这种植物作为他们的染料和药物的来源。R. stylosa还被证明含有一种二级生物活性和代谢物质,对人类和其他生物具有重要的价值。这项研究的目的是测试洋葱葱的根和染色体的乙醇R.苯酚提取物中次级代谢化合物的细胞毒性和genotoksilance水平。这项研究采用的是一种随机设计的实验方法,涉及11个统一浓度的分数(125 ppm),以及含水率和EMS溶液的负控制和积极控制,重复3次。观测参数包括有丝分裂指数、洋葱根生长和染色体abersion。使用ANOVA分析扫描Ft(α。05)和邓肯后续试验Ft(α05)。测试结果显示,密度125 ppm的11个分数分数出现了不同程度的有丝分裂指数的下降,并检测到染色体的分布频率不同。然而,11个分数并没有表现出丝分裂指数的潜质和致残性。可识别的染色体破损类型包括:rhizomus stylosa是一种红树林,很容易在印尼的大范围内找到。这棵植物作为医生和草药在社区中自由使用。R. stylosa还被称为对人类和其他有机体的生物活性和二线代谢物质的评估。这一研究将揭示从R. stylosa ethanolic leaf暴露在roots和chrosomes上的岩屑和二氧化物代谢和genotoxicity的证据。这项研究采用了一种完全融合设计的方法,采用了11个框架的方法,其中包含1 125 ppm的全部成分,以及EMS解决方案的负控制和负控制,每项作业3次重复。观察者观察到有谣言索引、洋葱根生长和色素吸收。《一名是analyzed ANAVA Ft(α。05)和邓肯跟着由Ft(α测试。05)。以125 ppm为中心的11帧的结果显示,存在着各种各样的谣言和扭曲频率的尴尬发现。However, 11帧并没有显示一个子lethal或致幻剂的虚幻指数。在chromosomal的特征中,观察到的是双主轴断裂、中期球、裂纹、c丝分裂、c丝分裂、c-有丝分裂、双桥、双环、分裂、严重缺陷、红细胞多动症、拉格德、微色情、微色情、核腐蚀、核外露、环、stickiness、vagrant。

期刊介绍: The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
