| 摘 要： | 重楼属是延龄草科一个特征鲜明的属,共约17—18种,分布于欧洲和亚洲,以中国为分布中心。在区别重楼属下各级类群时,最为有效的指标为:1.花基数(3-)4—10,花辫或萼片数与心皮数目相同;2.雄蕊2—6轮，其数目为心应数目(或萼片数,或花瓣数)的2—6倍;3.子房1室具(3-)4—10个侧膜胎座或数室而具中轴胎座,果为开裂的蒴果或不开裂的浆果;4.种子具多汁的假种皮、具不完全的假种皮或无假种皮;5.根状茎粗壮或细长匍匐.根据属内系统发育的趋势,可以确认:海南重楼Paris dunniana Levl．具粗厚根状茎、雄蕊4—6轮、子房1室具侧膜胎座、蒴果开裂、种于具完全的假种皮,是本属最原始的1个种。根据上述指标,本属划分为2个亚属7个组,其系统顺序如下.

| Abstract: | The structure of henryin, a new diterpenoid isolated from the dried leaves of Rabdosia henryi (Hemsl.) Hara, has been determined as (I ) on the basis of spectral and chemical evidence. Two known diterpenoids, kame- bakaurin (I ) and kamebacetal A (Ⅲ) were also isolated together with anotber new diterpenoid which will be published elsewhere. Based on the preliminary antitumoactivity test, compounds of (Ⅰ), (Ⅱ) and (Ⅲ) show a definite cytotoxic effect against Ehrlich carsinoma cells in vi-tro. |
