In this invistigation, we assessed the composition of the essential oil from the leaves of Artabortrys hexapetalus (L.f.) Bhandari, in vitro antioxidant and anticancer activities. The hydrodistilled essential oil from A. hexapetalus leaves cultivated in the southern Western Ghats was evaluated by GC/MS for its chemical composition. 34 compounds were present, according to the results of GC/MS analysis. The predominant constituents include Caryophyllene (17.2%), Copaene (12.9%), α-Bisabolene (8.3%), Biocyclogermacrene (6.3%), α-Cadinol (6.2%), β-Myrcene (5.7%), δ- 3-Carene (5.3%), and γ-Muurolene (4.9 %). The minor constituents are Gurjunene (3.5%), Longipinane (3.5%), Patchoulene (3.1%), Trans cadinal (2.8%), Ledol (1.4%), α-Phellandrene (1.3%), and Patchouli alcohol (1.3%). The DPPH and ABTS assays were used to measure the antioxidant activity of the A. hexapetalus essential oil, with ascorbic acid as a reference. The essential oil demonstrated antioxidant activity by having IC50 values of 104 and 122 µl/mL, respectively. Further the essential oil has tested its in vitro anticancer potential using the MTT assay on the HeLa cancer cell line and showed significant anticancer activity with an IC50 value of 36.7 µg/mL.

The current investigation is focused on the use of green synthesis methods for zinc oxide nanoparticles (ZnO NPs) from Scoparia dulcis L. extract (SDE). SDE-mediated ZnO NPs (SDE-ZnO-NPs) were made using a simple and eco-friendly method that required little reaction time and calcinations temperature. UV-Vis, FTIR, X-ray powder diffraction, SEM, TEM & EDAX were used into characterizes the skeletal and synthetic properties concerning biosynthesized ZnO nonmaterial. The UV–Visible spectroscopy absorption peak for SDE-ZnO-NPs was found to be at 380 nm, confirming the production of ZnO NPs. The FTIR spectrum also revealed bioactive functional groups as well as metal-oxygen groups. Synthesized ZnO NPs had a rod shape in 200 nm, according to TEM examination. The Zn and O in the produced ZnO NPs were approved by the EDAX analysis. The XRD results revealed that it had a crystal structure that was similar to SDE-ZnO-NPs. The dose-related Acetylcholinesterase inhibitory action of SDE-ZnO NPs was determined utilizing the Ellman’s test. AChE activity of the synthesized nanoparticles showed potential inhibitory activity with IC50 values of 75.34 µg/mL. The antioxidant activity was investigated the biosynthesized ZnO-NPs using DPPH, ABTS assay.
