A reinvestigation of the extracts from the starfish Distolasterias nipon, collected at Mutsu Bay, Japan, has led to the isolation of six glycosides of polyhydroxysteroids and six asterosaponins. Four steroidal glycosides have been identified as distolasterosides D1 [1] and D2 [2] (previously isolated from the same organism), and pycnopodioside C [5] and pisasteroside A [6], previously found in the related species Pycnopodia helianthoides and Pisaster ochraceus (family Asteridae), respectively. Two asterosaponins have been identified as the common versicoside A [7] and thornasteroside A [7a]. The two remaining glycosides of polyhydroxysteroids, named distolasterosides D4 [3] and D5 [4], and four asterosaponins designated nipoglycosides A [8], B [9], C [10], and D [11] are new compounds, and their structures have been elucidated mainly by interpretation of spectral data and comparison with known compounds.
对采自日本陆奥湾的多棘海盘车提取物进行的重新研究，已分离出六种多羟基甾体糖苷和六种海星皂苷。四种甾体糖苷已被鉴定为多棘海盘车苷D1 [1]和D2 [2]（先前从同一生物体中分离得到），以及海参皂苷C [5]和海盘车苷A [6]，它们分别先前在相关物种向日葵海星和赭色海星（菊海星科）中被发现。两种海星皂苷已被鉴定为常见的多疣海星苷A [7]和刺海星苷A [7a]。其余两种多羟基甾体糖苷，命名为多棘海盘车苷D4 [3]和D5 [4]，以及四种海星皂苷，命名为多棘糖苷A [8]、B [9]、C [10]和D [11]，均为新化合物，其结构主要通过光谱数据解析和与已知化合物比较得以阐明。
