Lavandula angustifolia biological characteristics: An in vitro study

Area of Science:

• Pharmacology
• Neuroscience
• Herbal Medicine

Background:

• Lavender (Lamiaceae family) is a traditional herbal medicine.
• Cognitive decline is linked to amyloid beta (Aβ) plaque accumulation, reduced acetylcholine, and glutamate excitotoxicity.
• Previous research demonstrated lavender extract enhances learning and memory.

Purpose of the Study:

• To evaluate the in vitro anti-amyloidogenic, antioxidant, and anti-acetylcholinesterase activities of lavender extract.
• To investigate the potential of lavender as a therapeutic agent for neurological disorders.

Main Methods:

• Qualitative and quantitative analysis using chromatography (TLC, HPLC).
• Assessment of anti-amyloidogenic properties via thioflavin and atomic force microscopy (AFM).
• Evaluation of antioxidant activity using 2,2-diphenyl-1-picryl hydrazyl (DPPH) assay.

Main Results:

• Lavender extract contains caffeic acid and luteolin-7-glycosid.
• Aqueous lavender extract demonstrated dose-dependent inhibition of Aβ aggregate formation.
• AFM confirmed significant reduction in Aβ fibril formation, alongside notable radical scavenging activity.

Conclusions:

• Lavender extract exhibits anti-amyloidogenic and antioxidant effects.
• The non-toxic nature of the extract supports its therapeutic potential.
• Lavender may be effective in managing neurological disorders, including Alzheimer's disease.
