The southwestern Indian paintbrush, Castilleja linariaefolia, yielded extracts that displayed in vivo activity against murine P-388 (PS) lymphocytic leukemia. Separation guided by PS cell line inhibition led to isolation of cytotoxic compounds that were identified as the known glycosides acteoside [1] (ED50 2.6 micrograms/ml) and isoacteoside [2] (ED50 10 micrograms/ml). The identifications were established by spectral measurements and degradation studies. Mannitol was also found in this plant.
西南印度马先蒿(Castilleja linariaefolia)产生的提取物对小鼠P - 388(PS)淋巴细胞白血病具有体内活性。以PS细胞系抑制为导向进行分离,得到了细胞毒性化合物,鉴定为已知糖苷毛蕊花糖苷[1](半数有效剂量2.6微克/毫升)和异毛蕊花糖苷[2](半数有效剂量10微克/毫升)。通过光谱测量和降解研究确定了这些化合物的结构。在这种植物中还发现了甘露醇。
