This is a laboratory analytical chemistry study that develops and validates a UV–visible spectrophotometric method for quantifying melatonin in soya lecithin nanovesicles and predicts in silico toxicity signals. The method shows linearity (R² = 1.0) and is stated to be precise, sensitive, and reproducible, but the work is exploratory and does not address clinical efficacy, in vivo safety, or bioavailability.
Analytical method development and validation study with in silico toxicity assessment. Intervention: UV–visible spectrophotometric method for melatonin quantification in soya lecithin transferosomes.
Coefficient of determination = 1.0 at 278 nm wavelength over concentration range 6–36 µg mL⁻¹, confirming linearity Method demonstrated to be precise, sensitive, robust, reproducible, and accurate In silico toxicity prediction: respiratory toxicity (84%), BBB toxicity (84%)
In silico toxicity predictions are computational models, not experimental validation In silico toxicity prediction: respiratory toxicity (84%), BBB toxicity (84%)
This method may be useful for pharmaceutical quality control and product characterization, but the in silico toxicity signals (respiratory and BBB toxicity at 84%) are computational predictions and require in vitro and in vivo validation before clinical relevance can be assessed.
This is a methods development study with analytical validation and computational toxicity prediction, not a clinical trial or efficacy study; it establishes a detection technique but does not test safety or efficacy in humans.

Abstract Phytoconstituents exhibit various effects, including antidiabetic, anticancer, cardioprotective, antioxidant, neuroprotective, and anti-infective effects. Across all the phytoconstituents, melatonin (MLT) has several beneficial effects. Basically, melatonin is secreted by the pineal gland. It is also available in most plants and plays key roles as a free radical scavenger, a potential agent for adjuvant therapy in cancer, a regulator of circadian rhythm, a management of insomnia (maintenance of the sleep cycle), an immunomodulatory agent, an anti-inflammatory agent, and more. Due to its low oral solubility, soya lecithin nanovesicles can help enhance its bioavailability. But detecting melatonin in nanovesicles is challenging. So, here we developed and validated a UV–visible spectrophotometric method for detecting melatonin in the nanovesicles. The method was developed in a buffer at a pH of 7.4. At a wavelength of 278 nm and over a concentration range of 6–36 µg mL –1, the coefficient of determination was 1.0, confirming linearity. The method was also demonstrated to be precise, sensitive, robust, reproducible, and accurate. In silico toxicity predicted respiratory toxicity (84 %) and BBB toxicity (84 %). This analytical method can be used to predict MLT in nanostructured products, large-dose forms, and various pharmaceutical preparations.
