Biocompatible nanoparticle synthesis from Strobilanthes hamiltoniana leaf extracts is an ecologically friendly, cost-effective and long-lasting technique for wastewater treatment, particularly for textile dye degradation. S. hamiltoniana mediated silver nanoparticles (SH-Ag NPs) showed a maximum absorbance of 432 nm. Based on the FESEM analysis, the SH-Ag NPs were usually spherical with an average diameter of nm. The FTIR analyses revealed the significance of functional groups in the formation of SH-Ag NPs. Degradation and rate of degradation for textile dyes after 320 min, SH-Ag NPs displayed 88.4%, 79.49%, 0.0059 min-1 and 0.00495 min-1 for reactive blue 220 (RB-220) and reactive blue 222A (RB-222A) dyes. The phytotoxicity study of SH-Ag NPs treated dye solutions demonstrated a significant decrease in inhibitory efficiency when compared to dye effluents. The biosynthesized SH-Ag NPs could represent a viable catalyst alternative for treating textile dye degradation both before and after it enters aquatic environments.

“…Different NPs such as silver [ 5 ], gold [ 6 ], copper [ 7 ], iron oxide [ 8 ], and zinc oxide [ 9 ] are successfully synthesized from Asteraceae members. The biosynthesis of NPs using plant extract of Asteraceae members is simple, easily available, low cost, and eco-friendly [ 10 , 11 ]. Numerous studies offering experimental data on the biological impacts of Asteraceae species have grown in recent years.…”

The Asteraceae family is one of the largest families in the plant kingdom with many of them extensively used for significant traditional and medicinal values. Being a rich source of various phytochemicals, they have found numerous applications in various biological fields and have been extensively used for therapeutic purposes. Owing to its potential phytochemicals present and biological activity, these plants have found their way into pharmaceutical industry as well as in various aspects of nanotechnology such as green synthesis of metal oxide nanoparticles. The nanoparticles developed from the plants of Asteraceae family are highly stable, less expensive, non-toxic, and eco-friendly. Synthesized Asteraceae-mediated nanoparticles have extensive applications in antibacterial, antifungal, antioxidant, anticancer, antidiabetic, and photocatalytic degradation activities. This current review provides an opportunity to understand the recent trend to design and develop strategies for advanced nanoparticles through green synthesis. Here, the review discussed about the plant parts, extraction methods, synthesis, solvents utilized, phytochemicals involved optimization conditions, characterization techniques, and toxicity of nanoparticles using species of Asteraceae and their potential applications for human welfare. Constraints and future prospects for green synthesis of nanoparticles from members of the Asteraceae family are summarized.

“…According to Reijnen et al (2017), ingesting approximately 42-91 g of yew leaves can be lethal to a 70 kg adult. Despite its toxicity, the species is intensively exploited for taxol, a compound used in cancer therapy (Wangkheirakpam and Laitonjam, 2016); at the same time, species of the Taxus genus are also ecologically and economically significant (Wang et al, 2023).…”

Taxus L. is accepted in the literature as natural resources of biologically active compounds and volatile oils, with applications in medicine, pharmaceuticals, food, cosmetics, and with ecological impact on the natural living environment. In this context, the present work aims to analyze by GS/MS techniques the chemical composition of volatile oil obtained by hydrodistillation of leaves harvested from spontaneous and cultivated female individuals of Taxus (dried and fresh plant material) and to spectrophotometrically evaluate the hydrosols resulting from their hydrodistillation. The compounds with the highest concentrations in the volatile oil obtained from the spontaneous taxon Taxus baccata L. were hexahydrofarnesyl acetone (33.03% fresh leaves; 20.09% dried leaves); ar-abietatriene (14.98% dried leaves; 3.03% fresh leaves); phthalic acid, hex-3-yl isobutyl ester (10.51% dried leaves); salicylic acid, benzyl ester (8.11% dried leaves). In the cultivated taxon Taxus baccata the compounds identified with the highest concentrations were 1-octen-3-ol (25.61% fresh leaves); phytol (12.50% dry leaves); geranyl acetone (11.90% dry leaves); manoyl oxide (11.85% dry leaves; 10.86% fresh leaves); 1,9-decadence (7.92% fresh leaves). The compounds with the highest concentrations in the oil extracted from the leaves of Taxus baccata ‘Robusta’ were hexahydrofarnesyl acetone (17.81% fresh leaves); pentacosane (11.28% dry leaves); heptacosane (11.27% fresh leaves); tetracosane (11.13% dry leaves); tricosane (8.45% fresh leaves). The chemical composition of volatile oils from yew is influenced by many exogenous factors such as soil, light, and endogenous factors such as age, DNA.
