Figure 3
The accumulated amounts of AR-derived chemicals during boiling process. The DBT was prepared as described in Section 2. Every 10 min, 0.5 mL of the preparing decoction was taken out. The temperature was recorded at the time of taking aliquot (see (c) bottom panel). After ~1.5 h, the boiling temperature reached 100°C, and the time interval of withdrawing sample was 30 min. In all aliquots, the amounts of calycosin-7-O-β-D-glucoside, calycosin, ononin, formononetin, and astragaloside IV were determined by RRLC-QQQ-MS/MS. The values are expressed in μg/g of the dry material and are in Mean ± SD, where , each with triplicate samples.
