  1. Extraction yield is the ratio of the amount of dry extract actually obtained, to the amount of dry herb samples used for extraction.
  2. Data are expressed as mean (SD).
  3. SD: standard deviation
  4. Means comparison was performed according to one-way ANOVA with α = 0.05.
  5. P > 0.05 for comparing extraction yields.
  6. P < 0.05 for comparing two major isoflavones in samples from northern and southern provinces.
