Tibesaikosaponin V (TKV) is a triterpene diglycoside, which can be isolated from the methanol extract of the roots of Bupleurum chinense DC. . Tibesaikosaponin V inhibits lipid accumulation and triacylglycerol content occurred without cytotoxicity to adipocytes. Tibesaikosaponin V suppresses the mRNA expression of nuclear transcription factors, such as peroxisome proliferator-activated receptor γ ( PPARγ ) and CCAAT/enhancer binding protein α ( C/EBPα ). Tibesaikosaponin V inhibits 3T3-L1 preadipocyte differentiation. Tibesaikosaponin V can be used fro research of obesity and its associated metabolic disorders IC50& Target:PPARγ
