From: Saponin accumulation in the seedling root of Panax notoginseng

Saponin Spiked (mg) Saponin detected mean (SD) (mg) Recovery rate (%) RSD (%)
R1 2.68 2.74 (0.07) 102.2 2.44
Rg1 18.91 20.12 (0.15) 106.4 0.85
Re 0.86 0.86 (0.02) 100.0 2.38
Rb1 10.60 11.27 (0.02) 106.3 1.81
Rd 2.12 2.08 (0.04) 98.1 1.49
  1. Recovery rate (%) = (mean of amount detected/spiked amount) × 100%
  2. RSD: relative standard deviation
