Serum biochemical analysis in different groups of aged rats after 12 weeks of treatment.

Group	AST	ALT	CREA	BUN
C	58.3 ± 4.8	16.3 ± 4.4	0.3 ± 0.1	7.7 ± 1.0
KGC01CE − 50	61.8 ± 11.8	17.0 ± 4.9	0.3 ± 0.1	7.6 ± 1.0
KGC01CE − 100	55.7 ± 20.2	17.0 ± 6.7	0.3 ± 0.2	6.8 ± 1.0
KGC01CE − 200	52.0 ± 9.5	13.3 ± 4.3	0.3 ± 0.1	7.3 ± 1.5

Data are expressed as mean ± standard deviation (n = 6). C: aged SD rats, KGC01CE − 50: aged SD rats + CE(1:3) 50 mg/kg b.w, KGC01CE − 100: aged SD rats +CE(1:3) 100 mg/kg b.w, KGC01CE − 200: aged SD rats +CE(1:3) 200 mg/kg b.w. ALT: alanine aminotransferase, AST: aspartate aminotransferase, BUN: blood urea nitrogen, CREA: creatinine.
