Colocynthin is a cucurbitane triterpenoid glycoside that can be isolated from the bitter apple (Citrullus colocynthis).

Gracillin can induce cell cycle arrest, oxidative stress, and apoptosis in HL60 cells, and has the potential to be developed as an antitumor agent.

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.
