生物活性
Isoescin IB 是從七葉樹種子中分離出來的，Isoescin IB 是 Escin IB 的異構(gòu)體。Isoescin IB 和 Escin IB 是 Escin 中的主要活性成分。體外研究
β-Escin (mainly consisting of escin Ia and escin Ib) is the major active ingredient in horse chestnut seeds extracts. β-escin can inhibit proliferation and/or induce apoptosis in various types of cancer cells including A549 cell, HT-29 cell, HCC cell, OVCAR3 cell and H-Ras 5RP7 cell. β-escin may be useful as a chemopreventive agent, especially for tumors associated with an inflammatory response.
As the minor component of escin, α-escin (mainly consisting of isoescin Ia and isoescin Ib) exhibits lower bioactivity.
