The eco-friendly control of mosquito vectors is a crucial challenge of public health importance. Here we evaluated the larvicidal potential of Artemisia absinthium essential oil (EO) and its three major chemical constituents against six mosquito vectors: Anopheles stephensi, Anopheles subpictus, Aedes aegypti, Aedes albopictus, Culex quinquefasciatus, and Culex tritaeniorhynchus. The EO was obtained by leaf hydrodistillation. Its chemical composition was analyzed using gas chromatography-mass spectrometry. Major components were (E)-β-farnesene (31.6 %), (Z)-en-yn-dicycloether (11.12 %), and (Z)-β-ocimene (27.8 %). The EO was toxic effect against larval populations of An. stephensi, An. subpictus, Ae. aegypti, A e . a l b o p i c t u s, C x . q u i n q u e f a s c i a t u s , and C x . tritaeniorhynchus, with LC 50 values of 41. 85, 52.02, 46.33, 57.57, 50.57, and 62.16 μg/ml. (E)-β-farnesene, (Z)-en-yndicycloether, and (Z)-β-ocimene were highly effective on An. stephensi (LC 50 = 8.13, 16.24 and 25.84 μg/ml) followed by An. subpictus (LC 50 = 10.18, 20.99, and 30.86 μg/ml), Ae. aegypti (LC 50 = 8.83,17.66, and 28.35 μg/ml), Ae. albopictus (LC 50 = 11.38,23.47, and 33.72 μg/ml), Cx. quinquefasciatus (LC 5 0 = 9.66, 19.76, and 31.52 μ g/ml), and Cx. tritaeniorhynchus (LC 50 = 12.51,25.88, and 37.13 μg/ml). Notably, the EO and its major compounds were safer to the non-target organisms Chironomous circumdatus, Anisops bouvieri and Gambusia affinis, with LC 50 values ranging from 207.22 to 4385 μg/ml. Overall, our results highlight that (E)-β-farnesene, (Z)-en-yn-dicycloether, and (Z)-β-ocimene from the A. absinthium EO represent promising eco-friendly larvicides against six key mosquito vectors with moderate toxicity against non-target organisms.

RESUMENObjetivo: Estudiar la actividad antioxidante y marcha fitoquímica de los capítulos de Tagetes filifolia Lag. "pacha anís". Materiales y métodos: Estudio de tipo experimental en el cual se empleó 5 kg de los capítulos de la planta medicinal Tagetes filifolia lag., provenientes de Junín. Se usó el método de cribado fitoquímico de Olga Lock para la marcha fitoquímica y el método DPPH para la determinación de la actividad antioxidante. Se dividió la muestra en 3 grupos: etéreo, alcohol etílico y agua destilada a concentraciones de 100, 50 y 5 μg/ml. Resultados: Se encontró fenoles en cantidades abundantes tanto en el extracto en agua destilada como en el extracto en alcohol etílico, además este último tuvo cantidades moderadas de quinonas. Por otro lado, el extracto en alcohol etílico fue el que presentó el mayor porcentaje de captación de radicales libres (91.26%) a una concentración de 100 μg/ml, similares resultados se encontró con el extracto etéreo (88.94%) y el extracto en agua destilada (75.58%). Conclusiones: Los principales componentes químicos fueron fenoles y quinonas. El mayor efecto antioxidante se obtuvo del extracto etanólico de la planta Tagetes filifolia a una concentración de 100 μg/ml. was used for the phytochemical screening and the DPPH method for the determination of the antioxidant activity. The sample was divided into 3 groups: ether, ethyl alcohol and distilled water at concentrations of 100, 50 and 5 μg/ml, respectively. Results: Abundant amounts of phenols were found in both the distilled water extract and the ethyl alcohol extract, and the latter had moderate amounts of quinones. Besides, the ethyl alcohol extract showed the largest percentage of freeradical scavenging (91.26%) at a concentration of 100 μg/ml. Similar results were found in the ether extract (88.94%) and the distilled water extract (75.58%). Conclusions:The main chemical components were phenols and quinones. The highest antioxidant effect was obtained from the ethanolic extract of Tagetes filifolia Lag. at a concentration of 100 μg/ml.

“…Such flower trash can be utilized in various ways to create useful products, which may also help to protect the environment from pollution brought on by the improper disposal of flowers dedicated to the gods. The literature has reported on various methods, such as the extraction of pigments and flavonoids, dye extraction, essential oil extraction, incense stick production, Holi color, biogas generation, and vermicomposting [65][66][67][68][69]. The details of a few of these value-added items obtained from marigold waste and their advantages are explained below and shown in Table 2.…”

The municipal authorities in developing nations face serious challenges in marigold flower garbage management. The primary issue is that they never are reused after prayers. Flower waste of Tagetes erecta, T. patula, and Calendula officinalis L. are commonly used for carotenoid and flavonoid extractions and, subsequently, used for incense stick and biogas production. Marigold plants are also used for phytoremediation during their growth stage. The lutein industry is booming due to its increasing market demand, expected to reach ~2121.2 billion tons by 2022, where marigolds are a major contributor globally. The process of isolating lutein from saponified marigold oleoresin yields a product with 70–85% purity. Lutein is a major xanthophyll (70–88%) of marigold petals, and a maximum of 21.23 mg/g of lutein was extracted. This review discusses the properties of selective marigold species, their compositions, and the extraction of different flavonoids and carotenoids, especially lutein. Moreover, different extraction methods of marigold lutein, the collection of marigold waste, and their subsequent utilization to derive several value-added products are discussed. Among physical treatments, ultrasonic-assisted extraction and enzymatic treatment with 5% solids loading were the maximum-yielding methods.
