Allelopathic effect of marigold (Tagetes erecta L.) leaf extract on growth of Chlorella vulgaris

Silver nanoparticle synthesis of the leaf extract Tagetes erecta L. enriched with ascorbic acid and polyphenols has been investigated. The color of the golden yellow extract has changed to pinkish-brown due to the reduction of Ag+ to the colloidal solution of AgNPs and a sharp absorption peak at 420 nm under the UV-Vis spectrophotometer. In addition, the Fourier Transfer Infrared Spectroscopy (FTIR) estimation was completed in order to recognize and identify the biomolecules present in the extract acting as a reducing and capping agent for the AgNPs. The X-ray diffraction (XRD) peaks at (111), (201), (220), and (311) confirm the presence of monoclinic crystals in the solution. The morphology and size of the particles were provided by transmission electron microscopy (TEM) images of AgNPs. At a scale of 100 nm, synthesized AgNPs were predominantly spherical with a size range of 7-35 nm. In comparison to 7.39 mg/100 g in AgNPs, aqueous leaf extract was 55.14 mg/100 g higher in ascorbic acid. The phenolic and flavonoid content of extract was 52.54 ± 2.15 mg (GAE/100 g) and 15.43 ± 0.34 mg (QE/mL), and the colloidal AgNP solution was 21.45 ± 1.15 mg (GAE/100 g) and 8.05 ± 2.42 mg (QE/mL), respectively. Phenolic and flavonoid contents play a major role as a reducing agent and reduce the precursor AgNO3 into AgNPs. The DPPH scavenging assay also assessed the antioxidant properties of extract and its derived AgNPs. As compared antioxidant value to aqueous leaf extract (mg/mL), higher percentage inhibition (PI) was found in AgNPs and free-radical scavenging activity of extract and AgNPs were directly linked to their concentrations. Results of this research have discovered a higher potential for free-radical scavenging AgNPs and will help to develop new and more potent antioxidants for the treatment of different diseases caused by oxidative stress; the higher antioxidant properties bearing AgNPs might be used.

Abstract Control of mosquito vectors by using natural ingredients is being developed intensively. Marigold (Tagetes erecta) was widely used as a mosquito repellent plant. The results of research before had found that marigold leaf extract has a repulsive effect on Aedes aegypti mosquitoes. This study aimed to identify the potential of marigold leaf extract as larvacide against Ae. aegypti larvae in the laboratory. The material used in this research was extracts of marigold leaves. Larvacide test was carried out by dissolving of extract in water at the concentration of 2,000 ppm, 4,000 ppm, 6,000 ppm, 8,000 ppm, and 10,000 ppm. The larvae used was Ae. aegypti larvae as many as 25 larvae each five treatment of replications. Probit analysis was conducted on larval mortality after 24 hours of exposure. The results of the probit analysis showed that the estimated concentration of extracts that could result in larval mortality up to 95% (LC95) was 7,456 ppm. From the result we can conclude that ethanol extract of marigold leaves (T. erecta L. ) has the biolarvacidal activity against larvae. Abstrak Pengendalian vektor nyamuk dengan memanfaatkan bahan alam makin banyak dikembangkan. Marigold (T. erecta) merupakan tumbuhan yang banyak dimanfaatkan sebagai tanaman pengusir nyamuk. Hasil penelitian sebelumnya menemukan bahwa ekstrak daun memiliki daya tolak terhadap nyamuk Ae. aegypti. Penelitian ini bertujuan untuk melihat potensi ekstrak daun marigold sebagai larvasida terhadap larva Ae. aegypti instar III di laboratorium. Bahan yang digunakan pada penelitian ini adalah ekstrak etanol daun marigold hasil ekstraksi dari penelitian sebelumnya. Uji larvasida dilakukan dengan melarutkan ekstrak dalam air pada konsentrasi 2.000 ppm, 4.000 ppm, 6.000 ppm, 8.000 ppm, dan 10.000 ppm. Larva yang digunakan yaitu larva Ae. aegypti sebanyak 25 larva tiap perlakuan dengan lima ulangan. Dilakukan analisis probit terhadap kematian larva setelah 24 jam paparan. Hasil analisa probit menunjukkan perkiraan konsentrasi ekstrak yang mampu mengakibatkan kematian larva hingga 95% (LC95 ) adalah 7.456 ppm. Ekstrak etanol daun marigold (T.erecta L.) memiliki potensi sebagai biolarvasida terhadap larva Ae. aegypti.
