Table 2 Method validation data for quantification of (−)-hydroxycitric acid and (−)-hydroxycitric acid lactone.
From: Authentication of Garcinia fruits and food supplements using DNA barcoding and NMR spectroscopy
Compound | LOD (mg/ml) | LOQ (mg/ml) | Relative standard deviation | Linear equation |
|---|---|---|---|---|
(−)-Hydroxycitric acid in Garcinia fruit extracts | 0.06 | 0.45 | 1.3% | y = 1.0143 × +100.92 R² = 0.9374 |
(−)-Hydroxycitric acid lactone in Garcinia fruit extracts | 0.04 | 0.71 | 2.1% | y = 2.8848 × +163.45 R² = 0.9974 |
