Most sensitive test for detection of argemone oil-
**Core Concept**
Argemone oil, derived from the seeds of Argemone mexicana, contains a toxic alkaloid called sanguinarine. This alkaloid can cause epidemic dropsy, a condition characterized by edema, shortness of breath, and other systemic symptoms. The detection of argemone oil is crucial to prevent its consumption and subsequent health issues.
**Why the Correct Answer is Right**
The most sensitive test for detecting argemone oil is the high-performance liquid chromatography (HPLC) method. This technique involves separating, identifying, and quantifying the components of a mixture based on their affinity for a stationary phase and a mobile phase. In this case, HPLC is used to detect the presence of sanguinarine, a specific alkaloid found in argemone oil. The HPLC method is highly sensitive and can detect even small amounts of sanguinarine, making it an ideal test for detecting argemone oil.
**Why Each Wrong Option is Incorrect**
* **Option A:** Thin Layer Chromatography (TLC) is a less sensitive method compared to HPLC and may not detect small amounts of sanguinarine.
* **Option B:** Gas Chromatography (GC) is not typically used for detecting alkaloids like sanguinarine.
* **Option C:** Enzyme-linked Immunosorbent Assay (ELISA) is not commonly used for detecting sanguinarine in argemone oil.
**Clinical Pearl / High-Yield Fact**
It's essential to note that argemone oil can contaminate mustard oil, which is a common cooking oil in some parts of the world. The presence of sanguinarine in mustard oil can cause epidemic dropsy, making it crucial to detect and prevent the consumption of contaminated oil.
**Correct Answer: D. HPLC**
