Green synthesis of zinc nanoparticles by hydroalcoholic extract of lavender (Lavandula stoechas L.), characterization, and cytotoxic effects on human breast and colon cancer
Open accessAbstract
Abstract Introduction Green synthesis is the production of metal nanoparticles (MNPs) with biological agents, including plant extracts, without special physical and chemical solutions and conditions. Due to their unique properties, MNPs are used in various sciences and industries. The study aimed to investigate the cytotoxic effects of zinc nanoparticles (ZnNPs) synthesized by the hydroalcoholic extract of lavender plant against human breast cancer cell lines (MCF7) and human colon cancer cell lines (HT29) with the approach of identifying the ability of these NPs to produce anticancer drugs. Method and Materials: ZnNPs are synthesized using the hydroalcoholic extract of the lavender plant. Evaluate and characterize nanoparticles (NPs) by Tyndall effect, UV-Vis, DLS, FT-IR, Zeta-P, Raman spectroscopy, SEM, AFM, and XRD methods. The cytotoxic effects of produced NPs against cancer cell lines MCF7 and HT29 and the healthy cells MCF10a and HGF were measured using the MTT method. Results: According to the findings of DLS analysis, the average size of ZnNPs is 40 and 50, respectively, at a concentration of 3 mM. The cytotoxicity of nanoparticles on MCF7 and HT29 cell lines produces the highest effect after 48 hours. Conclusion: The lavender plant is a suitable option for the green synthesis of ZnNPs and can be used as a stable source for production MNPs. Also, the synthesized ZnNPs showed cytotoxic effects against the examined cancer cells, while they did not cause toxicity to healthy human cells.

TL;DR
Hydroalcoholic lavender (*Lavandula stoechas* L.) extract was used to green-synthesize zinc nanoparticles (ZnNPs), which were characterized by multiple methods and tested against MCF7 breast cancer, HT29 colon cancer, and healthy MCF10a/HGF cells. The ZnNPs showed dose- and time-dependent cytotoxicity against cancer cells with lower toxicity to healthy cells after 48 h.
Key findings
- Optimal synthesis was reported at 3 mM zinc salt, pH 10, 25 °C, and 120 rpm; characterization by Tyndall effect, UV-Vis, DLS, FT-IR, Zeta-P, Raman, SEM, AFM, and XRD confirmed ZnNP formation. DLS gave a hydrodynamic diameter of 50 nm, SEM showed particles between 10 and 50 nm, Raman indicated 3–25 nm, and the discussion reports an average diameter of 27.62 nm; the Zeta-P section reports −27 mV.
- After 48 h, ZnNPs (A2) had IC50 values of 54.65 µg/mL in MCF7, 65.42 µg/mL in HT29, 140.2 µg/mL in HGF, and 100.1 µg/mL in MCF10a. Cisplatin IC50 values were 65.19 µg/mL in MCF7, 155.2 µg/mL in HT29, 76.38 µg/mL in HGF, and 55.48 µg/mL in MCF10a.
- Cytotoxicity was concentration- and time-dependent, with the highest effect reported after 48 h; normal HGF and MCF10a cells were more resistant to ZnNPs than the cancer cells.
- The paper concludes lavender is a suitable stable source for metal nanoparticle production and that the ZnNPs may have biomedical anticancer applications, while calling for further antibacterial, drug-delivery, and anti-adhesion studies.
Methods
- Lavender was collected around Qom, Iran, and identified as *Lavandula stoechas* L. (SBMU-8303). Hydroalcoholic extract was prepared from 200 g dried ground leaves in 1 L 50/50 distilled water–ethanol for 10 days at 25 °C in the dark, then filtered and evaporated at 45 °C. ZnNPs were synthesized with zinc sulfate/nitrate at 1–5 mM, pH 10, 25 °C, 120 rpm for 24 h, then isolated by ultracentrifugation.
- Characterization used Tyndall effect, UV-Vis, DLS, FT-IR, Zeta-P, Raman spectroscopy, SEM, AFM, and XRD.
- Cytotoxicity was tested by MTT assay on MCF7, HT29, MCF10a, and HGF cells obtained from IBRC. Cells were seeded at 5000 cells/well and treated with ZnNPs at 50, 100, 150, 250, and 300 µg/mL and cisplatin; plates were incubated for 24, 48, and 72 h, and optical density was read at 570 nm. IC50 values were calculated with GraphPad Prism 8.2.1 using non-linear regression dose-response curves.
Limitations
- The paper states that only 48 h results are reported because 24 h was too short for drug effect and 72 h data were unreliable due to culture medium consumption by cells.
- The paper states that large-scale green synthesis still faces obstacles including uncontrollable final nanoparticle size and shape, difficult scalability, wide raw-material variety, and limited raw-material availability at different times.
- Evident from the text: all cytotoxicity data are in vitro, with no in vivo or clinical validation; mechanistic claims about apoptosis, cell cycle disruption, and reactive oxygen species are discussed but not experimentally tested in this paper.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-11-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-11-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
