从采自宁夏的萝摩科鹅绒藤属植物牛心朴子 (CynanchumkomaroviiAl.Iljinski.)须根的乙醇提取物中分离鉴定了十个非C2 1 甾体类化合物 :β D 呋喃果糖基 (2→ 1) α D [6 O 芥子酰基 ] 吡喃葡萄糖甙 (1) ,β D (3 O 芥子酰基 ) 呋喃果糖基 (2→ 1) α D [6 O 芥子酰基 ] 吡喃葡萄糖甙 (2 ) ,[6 O β D 吡喃葡萄糖基 (1→ 6 ) β D 吡喃葡萄糖基 1,2 双氧 (4 羟基 3,5 二甲氧基肉桂酰 ) (3) ,7 脱甲氧基娃儿藤碱 (4) ,9 羟基 芳樟醇 3 O β D 吡喃木糖基 (1→ 6 ) β D 吡喃葡萄糖甙 (5 ) ,(2E ,6R) 2 ,6 二甲基 2 ,7 辛二烯 1,6 二醇 (6 ) ,[(+) 丁香素 ](7) ,4′ O demethylepiyangambin(8) ,4′ 羟基 2′ 甲氧基苯乙酮 (9) ,(2S ,3S ,4R ,12E) N [2′ (R) 羟基二十二碳烷基 ] 1,3,4 三羟基 2 酰胺 二十碳烷基 12 烯 (10 )。除化合物 4和 9外 ,其余化合物均为首次从该植物中分离得到。
Ten non-C2 steroid compounds were isolated and identified from the ethanol extract of the fibrous roots of Cynanchum komarovii Al.Iljinski. The β 2 -fructofuranosyl (2 → 1) α D [6 O mustardyl] glucopyranoside (1), β D (3 O mustardyl) fructofuranosyl (2 → 1) α D [6 O mustardyl] glucopyranoside (2) β D glucopyranosyl (1 → 6) β D glucopyranosyl 1,2 dioxy (4 hydroxy 3,5 dimethoxy cinnamoyl) (3), 7 desmethoxyvalerine (4 ), 9-hydroxy linalool 3 O β D xylopyranosyl (1 → 6) β D glucopyranoside (5), (2E, 6R) 2, 6 dimethyl 2,7 octadiene 1, (9), (2S, 3S, 4R, 12E) 6 diol (6), [(+) menthylbenzoate], 4’O demethylepiyangambin (8) N [2 ’(R) hydroxybeuricyl] 1,3,4 trihydroxy 2 amide eicosyl 12 alkene (10). Except for compounds 4 and 9, all other compounds were isolated from this plant for the first time.
