A) HPLC analysis of extracts. Statistical differences between RKW and RKW-A extracts: salidroside (1) p < 0.05, kaempferol (2) p < 0.001, ellagic acid (3) p < 0.001, quercetin (4) p < 0.01; chlorogenic acid (5), (+)-catechin (6), epicatechin (7), epigallocatechin (8): p < 0.0001. Unpaired t test. B) HPLC analysis of mothers sera. Statistical differences between RKW and RKW-A sera: salidroside (1) p = 0.03, kaempferol (2) p = 0.0652 (on the border of significance), (+)-catechin (6) and epicatechin (7) p = 0.001. Unpaired t test
