Abstract

Guava (Psidium guajava) is a popular tropical plant widely used as processed food and medicine for various diseases. This plant contains highly bioactive compounds like quercetin, flavonoids, and ferulic acid. The bioactive content can be influenced by the extraction method. However, the solvent used for extraction can also affect the bioactive content. Therefore, this study aims to determine the best solvent or combination of extraction solvents to extract guava leaves based on total phenolic content (TPC) and antioxidant activity using simplex centroid design (SCD). This research used guava leaf samples with various solvent combinations of water, ethanol, and acetone. The determination of phenolic content was determined using the TPC method, while the determination of antioxidants was conducted using the FRAP and ABTS methods. The research results showed that the highest TPC levels were produced by the solvent water : ethanol : acetone. Then the highest levels of FRAP and ABTS antioxidants were produced by the water: ethanol solvent. The solvent optimization solution obtained was using water: ethanol: acetone with a ratio of 0.462:0.436:0.102, respectively.

Abstract

Celosia cristata L. atau jengger ayam merupakan tanaman hias dengan bentuk yang unik. Peningkatan keragaman C. cristata melalui teknik hibridisasi terkendala karena bunganya berbentuk bulir dan berukuran kecil sehingga menyulitkan proses kastrasi dan isolasi organ reproduksi. Induksi mutasi merupakan salah satu cara yang dapat digunakan untuk meningkatkan keragaman. Tujuan penelitian ini adalah mendapatkan informasi keragaman karakter agro-morfologi pada 17 genotipe mutan M3 jengger ayam hasil induksi mutasi sinar gamma di kebun percobaan Sabisa Farm. Karakter kualitatif dan kuantitatif yang terkait dengan agro-morfologi diamati berdasarkan deskriptor Union for The Protection of New Varieties of Plants (UPOV) yang dimodifikasi. Analisis ragam dilakukan menggunakan SPSS 20.0, sedangkan analisis kemiripan dengan menggunakan PBSTAT-CL 2.1. Keragaman signifikan antar genotipe C. cristata (p < 0.05) terdapat pada karakter tinggi tanaman dan panjang bunga. Tiga kelompok berdasarkan karakter agro-morfologi terbentuk dari analisis kemiripan pada koefisien ketidakmiripan 32%. Hasil mengindikasikan bahwa karakter karakter agro-morfologi dapat digunakan untuk membedakan 17 genotipe mutan M3 jengger ayam yang diteliti, sehingga dapat digunakan untuk pengembangan penelitian selanjutnya dalam program pemuliaan tanaman.

Abstract

Cardamom (Amomum cardamomum) is a herbal plant with various phytochemical compounds such as phenols, starch, tannins, terpenoids, flavonoids, and antioxidants. Cardamom of the same type but originating from different regions can produce variations in the content of metabolites. This study aimed to select cardamom accession containing high starch, chlorophyll, and antioxidant capacity. The research was conducted at Biopharmaca Experimental Garden, Cikabayan IPB University from March to August 2022 using four cardamom accessions, i.e., Bogor Hijau, Bogor Merah, Ciamis and Sukabumi. Three leaves were taken for each accession, with three replications. The leaves taken were numbers 5, 6, and 7 counted from the tops of the cardamom plant. The methods used in this study were the phenol-sulfuric acid method, the DMSO method, the DPPH method, and the CUPRAC method. The results showed that the highest starch content was produced by the cardamom of Bogor Merah accession, with an average of 3.63 g (100 g)-1 FW. The highest total chlorophyll content was found in the cardamom of Bogor Hijau accession, with an average of 1.9 mg g-1 FW. At the same time, the highest antioxidant capacity using the DPPH method was produced by the cardamom of the Sukabumi accession with an average of 1.28 μmol TE g-1 FW. In comparison, the highest antioxidant capacity of the CUPRAC method was produced by the cardamom of the Bogor Hijau accession with an average of 5.71 µmol TE g-1 FW. Thus, it is recommended to use Bogor Merah dan Bogor Hijau accession for further evaluation. Keywords: accession, antioxidant activity, cardamom leaves, chlorophyll, starch

Abstract

Green spinach (Amaranthus tricolor L.) is a plant that contains various vitamins, such as vitamins A, B, and C, as well as protein and fiber. Green spinach contains high iron. Besides that, spinach also contains secondary metabolites such as flavonoids, antioxidants, and phenolics, which are beneficial for degradative diseases. This study aimed to evaluate the impact of plant height, iron content, total phenolic content, and antioxidant activity in spinach plants using a 70% ethanol solvent. The samples were extracted through a maceration method in a microwave for 3 minutes, followed by filtration to obtain the test sample filtrate. Iron content was determined using the ICP-OES method, total phenolic content (TPC) was measured with the Folin-Ciocalteu method, and antioxidant activity was assessed using the DPPH method. The findings revealed that treatment 2 (2 parts maggot fertilizer to 8 parts soil) had the highest iron content and antioxidant activity, whereas treatment 1 (1 part maggot fertilizer to 9 parts soil) showed the greatest plant growth and phenolic content.
