A chloroform extract of the whole plant of Anaphalis morrisonicola HAY, showed significant antitumor activity against Ehrlich ascites carcinoma, Walker 256 carcinosarcoma, and P-388 lymphocytic leukemia. Systematic fractionation of the extract led to isolation and characterization of helenalin, a pseudoguaianolide, as the major active principle.
玉山香青全株的氯仿提取物对艾氏腹水癌、沃克256癌肉瘤和P - 388淋巴细胞白血病显示出显著的抗肿瘤活性。对该提取物进行系统分离，得到了一种假愈创木烷型倍半萜内酯——堆心菊灵，并将其鉴定为主要活性成分。
