Abstract

Kadmium merupakan salah satu logam berat yang bersifat toksik dan dapat diserap oleh tumbuhan. Tagetes erecta merupakan tanaman hias yang memiliki kemampuan toleransi yang tinggi terhadap cekaman logam berat, sehingga tanaman ini dapat digunakan sebagai agen fitoremediasi. Tujuan dari penelitian ini adalah untuk mengetahui efek dari cekaman logam berat pada proses perkecambahan dan pertumbuhan benih T. erecta pada media pupuk cair yang mangandung Cd. Penelitian dilakukan secara eksperimental menggunakan desain rancangan acak lengkap. Konsentrasi CdCl2 yang digunakan sebagai perlakuan antara lain 0 (kontrol), 25, 50, 100, dan 200ppm. Biji T. erecta dikecambahkan di dalam cawan petri yang dialasi dengan kertas merang dan ditutup dengan plastik berwarna gelap. Perkecambahan dilakukan di laboratorium. Parameter jumlah biji yang berkecambah diamati setiap hari selama 14 hari digunakan sebagai penentuan persentase perkecambahan dan indeks vigor kecambah. Pertumbuhan kecambah diamati pada parameter panjang radikula dan panjang hipokotil pada akhir penelitian. Pemberian perlakuan kadmium mempengaruhi secara nyata perkecambahan dan pertumbuhan kecambah T. erecta. Kadmium pada konsentrasi 100-200 ppm menghambat secara nyata perkecambahan dan pertumbuhan kecambah T. erecta. Pertumbuhan radikula T. erecta pada perlakuan Cd sebesar 25ppm menunjukkan ukuran yang lebih panjang dibanding perlakuan kontrol. Hal ini dikarenakan penambahan kadmium pada konsentrasi rendah sebesar 25ppm masih mampu ditoleransi dan merangsang pertumbuhan kecambah T. erecta. Cadmium is one of the heavy metals that is toxic and can be absorbed by plants. Tagetes erecta is an ornamental plant that has a high tolerance to heavy metal stress, so this plant can be used as a phytoremediation agent.  The purpose of this study was to determine the effects of heavy metal stress on the process of germination and growth of T. erecta seeds in liquid fertilizer media containing Cd. The research was conducted experimentally using a completely randomized design. The concentration of CdCl2 used as treatment included 0 (control), 25, 50, 100, and 200ppm. T. erecta seeds were germinated in a petri dish covered with straw paper and covered with dark colored plastic. Germination was carried out in the laboratory. The number of germinated seeds observed daily for 14 days was used to determine the germination percentage and vigor index of the sprouts. Sprout growth was observed in the parameters of radicle length and hypocotyl length at the end of the study. Cadmium treatment significantly affected the germination and growth of T. erecta sprouts. Cadmium at concentrations of 100-200 ppm significantly inhibited the germination and growth of T. erecta sprouts. Radicle growth of T. erecta in the Cd treatment of 25 ppm showed a longer size than the control treatment. This is because the addition of cadmium at a low concentration of 25 ppm can still be tolerated and stimulate the growth of T. erecta sprouts.

Abstract

 Mistletoe, a parasitic plant growing on nutmeg trees, is conventionally perceived as a parasitic entity with limited regard for its potential medicinal value. On the other hand, mistletoe has a remarkable potential source of valuable medicinal compounds, particularly in traditional healthcare, due to its secondary metabolites such as flavonoid, phenolic, ascorbic acid, and antioxidant activity. Nevertheless, both the host tree and the environment, like Pb, influence the adaptive responses of secondary metabolites. This study aimed to determine the secondary metabolites, such as flavonoids, phenolics, ascorbic acid, antioxidant activity, and Pb content in the leaves of D. vitellina and nutmeg (M. fragrans). The samples were obtained via maceration using ethanol. The spectrophotometric analysis method was used to measure several parameters, using particular reagents for phenolic compounds using Folin-Ciocalteu, flavonoids using AlCl3, and ascorbic acid using sulfosalicylic acid), antioxidant activity using DPPH, and Pb using the AAS method. The results indicated that D. vitellina possesses a higher concentration of flavonoid and phenolic compounds, followed by 3.36 ± 1.92 % (w/w) and 18.45 ± 2.35 % (w/w) respectively. Conversely, nutmeg had a significant ascorbic acid concentration of 3.99 ± 4.38 % (w/w). The significant presence of phenolics and flavonoids had a crucial role in the antioxidant activity seen in D. vitellina, which exhibited exceptionally potent antioxidant properties. All samples contain Pb, ranging from 0.00001–0.00021 % (w/w), within the maximum allowable limits. Therefore, mistletoe is notable for being a reliable and encouraging plant species that can provide a natural supply of antioxidants and be safely used in traditional medicine.

Abstract

Currently, the public is interested in polyherbal-based foods and beverages as a source of natural antioxidants. The aim of the study is to evaluate the antioxidant properties and the phenolic and flavonoid compounds of formulations containing Z. officinale, C. citratus, and P. reticulatus (ZCP). Each sample was extracted using the maceration process in an ethanol solvent at room temperature for three 72-hour periods. There were fourteenth formulation of Z. officinale rhizome, C. citratus leaves, and P. reticulatus fruit which used Design of Expert (DoE). The DPPH method was used to determine the power of antioxidants. The flavonoid content of the extract was measured using the colorimetric method and AlCl3 reagent, while phenolics content using Folin-Ciocalteu. The formulations ZCP 1:0:0, 0:0:1, and 1:1:1 showed the antioxidant capacity in a strong categorization, with an IC50 value less than 50 µg/ml, while ZCP 0:1:0 was in a weak categorization (IC50 > 250 µg/ml). Another ZCP formulation was in a medium category. The ZCP 1:1:1 formulation was suggested as the best one for this investigation, which contains three plant samples. This formulation is interesting for further toxicity studies and in vivo testing so that it can be applied as an antioxidant-rich supplement product.

Abstract

Phylanthus species, including P. niruri and P. urinaria have pharmacological potential due to their rich phytochemical composition. People usually used this plant for medicinal treatments. This study aimed to compare the phytochemical and antioxidant and antibacterial activities of two Phyllanthus species. The whole of plants was extracted using maceration method with ethanol as solvent. Phytochemical content analyzed using spectrophotometer.  The reagent used for each compounds that were Folin-ciocalteu for phenolics, AlCl3 for flavonoid, dimethyl sulfoxide for chlorophyll and carotenoid. Bioactivity analysis using 1,1-diphenyl-2-picrylhydrazyl method for antioxidant activity and Kirby-Bauer method for antibacterial activity. The highest flavonoid content (12.22 mg QE/gram extract) and total chlorophyll (43.2 µg/ml extract) in P. niruri while phenolic content (80.8 mg GAE/gram extract) in P. urinaria. The carotene of both Phyllanthus were similar (11.9 µg/ml extract. The IC50 values of P. urinaria (6.16 ± 0.42 μg/ml) and P. niruri (17.72 ± 0.80 μg/ml), which indicated very strong antioxidant activity. P. urinaria leaf extract had stronger inhibition against Escherichia coli than Staphylococcus aureus (>20 mm) and P. niruri leaf extract could inhibit E. coli and S. aureus bacteria at all concentrations (11-20 mm). This study found that phenolic compounds strongly influenced the antioxidant and antibacterial abilities of Phyllanthus, while chlorophyll and carotenoids had only a slight influence. These findings open up opportunities to utilize P. niruri and P. urinaria as antioxidant and antibacterial agents.

Abstract

People use ginger (Zingiber officinale) extensively for health purposes. Our previous studies have shown that Phyllanthus reticulatus has strong antioxidant capabilities. This study investigates the anticancer potential of ethanolic extract of Z. officinale and P. reticulatus formulations (ZP), focusing on their cytotoxicity and mechanisms against cancer cells. Samples were extracted using the maceration method. The method for determining the cytotoxicity of cells is MTT, the cell cycle is flow cytometry, apoptotic cells are flow cytometry and double staining, and caspase-8 and caspase-9 expression using the immunocytochemistry method. The analysis of caspase-8 and caspase-9 expression using the immunocytochemistry method. Among the tested formulations, the ethanolic extract of ZP_1:0 showed the most promise against WiDr colon cancer cells (IC50 value of 102.1 µg/ml). The ZP_1:0 demonstrated dose-dependent apoptosis induction in WiDr cells, showing early and late apoptosis, with minimal necrosis. The extract activates extrinsic and intrinsic apoptotic pathways in inducing cancer cell death. Compared to doxorubicin, the ZP 1:0 formulation selectively promotes apoptosis with reduced necrotic damage, suggesting the potential for reduced systemic toxicity. The study supports the potential of Z. officinale as a source of safer, plant-based anticancer agents, particularly for colon cancer, while recommending further research to identify and enhance active compounds.

Abstract

The oxidation of Cr(III) to Cr(VI) in the environment has a detrimental impact because it can change the form of non-toxic Cr(III) to Cr(VI), which is toxic to organisms. The study aimed to examine the effect of the application of iron (Fe) and trivalent chromium (Cr(III)) compounds in Tagetes erecta growing media on growth and Cr(III) oxidation. Concentrations of Cr(III) 0, 100, and 500 mg/L and Fe 0, 3, 15, and 30 mg/L were applied to the growing media of T. erecta as the model plant. The growth and accumulation of Cr(VI) in plants were measured to determine the effect of Fe and Cr(III) treatment on growth and Cr(III) oxidation. The accumulation of Cr(VI) in the roots and shoots of T. erecta increased significantly due to the addition of Fe in the growing media treated with Cr(III). The highest accumulation of Cr(VI) in the roots and shoots of T. erecta found in the treatment of Cr(III) 500 mg/L and Fe 30 mg/L, were respectively 0.092 g/L and 0.070 g/L. The addition of Fe in growing media containing Cr(III) increased plant height, root length, and shoot dry weight but decreased leaf number and root dry weight. T. erecta root biomass was more affected by the toxic impact of Fe than Cr(III). On the other hand, the inhibition of leaf formation was caused by the toxic effect of Cr(III) rather than Fe.
