Abstract. Wahyuni DK, Rahayu S, Purnama PR, Saputro TB, Suharyanto, Wijayanti N, Purnobasuki H. 2019. Morpho-anatomical structure and DNA barcode of Sonchus arvensis L. Biodiversitas 20: 2417-2426. Tempuyung or show thistle (Sonchus arvensis L.) belongs to the Asteraceae. Morpho-anatomy and DNA (Deoxyribonucleic Acid) barcoding of the plant correlates with species identification and metabolite synthesis. This research aims to look at morpho-anatomical structures and analyze the DNA barcode of Sonchus arvensis L (tempuyung). Three samples used for morpho-anatomical analysis are leaves, stems, roots, fruit, and seeds. Anatomical samples are made using the embedding method. DNA barcode uses multiple locus from plastid genome: rbcL and matK. Morpho-anatomical structure of tempuyung showed a similar structure of Sonchus genus. The stem presents in the intercellular space, whereas the roots and leaves present in the vascular tissue and the seeds. Fruits present in each part of the body. Tissues that formed root are epidermis, cortex, endoderm, and stele. Tissues that formed stem are epidermis, cortex, and stele. Tissues that formed leaf are epidermis, cortex, phloem, and xylem. Tissues that formed the fruit and seed are paranormal and sclerenchyma tissues. Sonchus arvensis sequence for rbcL has a similar 100% maximum identity to rbcL gene of S. arvensis, Sonchus asper, and Sonchus oleraceus, whereas Sonchus arvensis matK sequence has a similar 99.31% maximum identity to other S. arvensis matK sequences in BLAST system. These findings provide morpho-anatomical features and DNA barcoding for identification of S. arvensis. from others species in the same genus. Thus also can be considered as pharmaceutical standard.
Malaria is still a global health problem. Plasmodium is a single-cell protozoan parasite that causes malaria and is transmitted to humans through the female Anopheles mosquito. The previous study showed that Sonchus arvensis L. callus has antiplasmodial activity. Several treatments are needed for callus quality improvement for antimalarial compound production. This study aimed to examine the effect of dolomite [CaMg(CO3)2] on growth (morpho-anatomical structure and biomass), secondary metabolite production, and in vitro antiplasmodial activity of S. arvensis L. callus. In this study, leaf explants were grown in Murashige and Skoog medium with a combination of 2,4-dichlorophenoxyacetic acid (2,4-D, one mg/L) and 6-benzyl amino purine (BAP, 0.5 mg/L) with dolomite (50, 75, 100, 150, and 200 mg/L). The 21 days callus ethanolic and methanolic extract were analyzed by gas chromatography-mass spectrometry (GC-MS) and thin-layer chromatography (TLC). The antiplasmodial test was performed on a blood culture infected with Plasmodium falciparum strain 3D7 using the Rieckmann method. The results showed that dolomite significantly affected callus growth, metabolite profile, and in vitro antiplasmodial activity. Dolomite (150 mg/L) showed the highest biomass (0.590 ± 0.136 g fresh weight and 0.074 ± 0.008 g dry weight). GC-MS analysis detected four compounds from callus ethanolic extract. Pelargonic acid, decanoic acid, and hexadecanoic acid were major compounds. One new terpenoid compound is based on TLC analysis. S. arvensis L. callus has antiplasmodial activity with the IC50 value of 5.037 μg/mL. It was three times lower than leaf methanolic extract and five times lower than leaf ethanolic extract.
AbstrakVanda hookeriana Rchb.f. merupakan anggrek yang dilindungi dan keberlangsungan hidupnya di alam terancam punah, sehingga perbanyakan anggrek secara in vitro sangat diperlukan. Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak yeast dan pisang raja terhadap pertumbuhan tunas embrio anggrek V. hookeriana Rchb.f. Desain penelitian ini menggunakan RAL faktorial, faktor pertama adalah ekstrak yeast dengan 3 taraf: 0,5 g/L, 1 g/L, dan 1,5 g/L, faktor kedua adalah buah pisang raja dengan 3 taraf: 50 g/L, 100 g/L, dan 150 g/L. Penelitian dilakukan menggunakan teknik kultur jaringan, pengamatan dilakukan setiap bulan sekali dengan mengamati aspek morfologi plantlet. Media yang digunakan adalah Vacin-Went (VW) + kombinasi ekstrak yeast dan pisang raja. Parameter pengamatan berupa tinggi tunas, berat kering tunas, jumlah daun, diameter daun, panjang daun, berat kering daun, jumlah akar, diameter akar, panjang akar, berat kering akar, dan morfologi tunas. Hasil analisis menunjukkan bahwa perlakuan pisang raja 150 g/L + ekstrak yeast 0,5 g/L merupakan konsentrasi yang paling berperan terhadap parameter pertumbuhan anggrek V. hookeriana Rchb.f. Penelitian ini berhasil membuktikan bahwa penambahan komponen organik dalam media kultur jaringan memberikan respon pertumbuhan dan perkembangan yang baik pada eksplan. Komponen organik membantu proses fisiologis eksplan, karena komponen organik mengandung senyawa potensial yang dibutuhkan selama proses pertumbuhan dan perkembangan. Abstract Vanda hookeriana Rchb.f. is one of protected orchid and its survival in the wild was threatened by extinction, so orchid propagation was needed. This research aimed to determine the effect of yeast and pisang raja extracts to embryonal shoot growth of Vanda hookeriana Rchb.f. Experimental design used factorial RAL, first factor was yeast extract with 3 treatments (0.5 g/L; 1 g/L; & 1.5 g/L). Second factor was pisang raja with 3 treatments (50 g/L; 100 g/L; & 150 g/L). The research was conducted using in vitro culture techniques, observations were made once a month by observing the plantlet morphological parameters. The medium used was Vacin-Went (VW) + combination of yeast and pisang raja extracts. Observation parameters were shoot height, shoot dry weight, leaf number, leaf diameter, leaf length, leaf dry weight, number of roots, root diameter, root length, root dry weight and shoot morphology. The analysis showed that pisang raja treatment 150 g/L + yeast extract 0.5 g/L was the best concentration for the growth parameters of Vanda hookeriana Rchbf. This research were succeeded in proving that the addition of organic components in tissue culture media gave better response to growth and development of the explants. Organic components helps the explants in physiological ways because of the organic components contain potential compounds needed during the growth and development process.
Tempuyung (Sonchus arvensis L.) merupakan tanaman yang memiliki banyak manfaat dan berpotensi sebagai obat. Tanaman ini diketahui memiliki kandungan flavonoid dan terpenoid yang tinggi. Propagasi tanaman ini sangat penting dilakukan untuk menyediakan bahan obat dalam skala prabikasi dan menghasilkan bahan yang memiliki kandungan senyawa yang tinggi. Metode kultur jaringan merupakan salah satu cara yang cepat dalam propagasi tanaman dan dapat meningkatkan kandungan metabolit sekunder dalam tanaman. Metode untuk menghasilkan senyawa yang tinggi dan menghasilkan somatik embrio dalam jumlah yang banyak dapat melalui kultur kalus. Tujuan penelitian adalah ingin mencari pengaruh hormon 2,4D dan BAP serta variasi eksplan daun terhadap pertumbuhan kalus tempuyung. Pada penelitian ini digunakan kombinasi hormon 2,4D (0; 0,5; 1 ppm) dan BAP (0; 0,5; 1 ppm) dalam menginduksi kalus, dan eksplan yang digunakan pada penelitian ini adalah daun vegetatif dan daun generatif tempuyung. Hasil penelitian ini menyatakan bahwa kalus dihasilkan dalam waktu 10-14 hari, dengan jenis kalus friabel dan berwarna kuning. Eksplan daun vegetatif lebih cepat inisiasi kalusnya disbanding daun generatif. Hasil lain menunjukkan bahwa kombinasi terbaik dalam produksi adalah BAP 0,5 ppm dan 2,4D 1 ppm, dan eksplan daun yang paling optimal dalam menghasilkan kalus terdapat pada eksplan daun vegetatif.
