6hydroxykaempferol

6-Hydroxykaempferol (6-羟基山奈酚) 是一种竞争性酪氨酸酶抑制剂(IC50=124 nM)，属于黄酮类化合物,是一种来源于红花（Carthamus tinctorius）的天然产物。 相较于L-DOPA,6-Hydroxykaempferol能够以更高的活性结合酪氨酸酶的活性位点，同时具有高抗氧化活性。

6-Hydroxykaempferol 3,6-diglucoside是一种发现于Carthamus tinctorius的天然产物，能够抑制胶原诱导的血小板聚集。

6-Hydroxykaempferol 3-O-beta-D-glucoside has anti-thrombotic,and antioxidative activities.

6-Hydroxykaempferol 3-Rutinoside-6-glucoside是一种发现于Carthamus tinctorius的天然产物，具有抗氧化活性。

6-Hydroxykaempferol 7-O-β-glucopyranoside (compound 5) 为一种从野生万寿菊（Tagetes minuta）中提取的黄酮醇。

6-Hydroxykaempferol 3,6,7-tri-O-glucoside and 6-hydroxykaempferol 3,6-di-O-glucoside can inhibit platelet aggregation induced by collagen, they also show weak inhibitory effects on the adenosine 5'-diphosphate (ADP)- induced platelet aggregation.
