从滇姜花（ＨｅｄｙｃｈｉｕｍｙｕｎｎａｎｅｎｓｅＧａｇｎｅｐ．）根茎中分离到两个具抗肿瘤活性的二萜成分滇姜花素Ｃ及滇姜花素Ａ，前者为新化合物，其结构经波谱及化学方法鉴定。此新化合物亦可从滇姜花素Ａ的光敏氧化反应产物中分离得到。
From the rhizome of Hedychium yunnanense Gagnep., two anti-tumor active diterpenoids, Gingerine C and Gingerin A, were isolated. The former is a new compound whose structure was identified by spectral and chemical methods. The new compound can also be isolated from the photooxidation reaction product of azulene A.
