从民间药物钮子瓜全草95%乙醇提取物中首次分离得到14个化合物,应用波谱方法及与已知品对照的手段鉴定它们为(2S,3S,4R,10E)-2-[(2R)-2-羟基二十四烷酰氨基]-10-十八烷-1,3,4-三醇(1)、(2S,3S,4R)-2-二十四烷酰胺基-十八烷-1,3,4-三醇(2)、胡萝卜苷(3)、swertish(4)、苯甲酸(5)、水杨酸(6)、loliolide(7)、胸腺嘧啶(8)、尿嘧啶(9)、(23Z)-9,19-环阿尔廷-23-烯-3β,25-二醇(10)、(20S,22E,24R)-5α,8α-表二氧-麦角甾-6,22-二烯-3β-醇(11)、十六烷酸-1-甘油酯(12)、大豆脑苷Ⅰ(13)、(22E,24S)-24-甲基-5α-胆甾-7,22-二烯-3β,5α,6β-三醇(14).%Fourteen compounds were isolated from the 95 % ethanol extract of the whole plants of folk medicinal herb Zehneria maysorensis for the first time. On the basis of spectral data or comparison with authentic samples, they were characterized to be (2S, 3S, 4R, 10E) - 2- [(2R) - 2- hydroxytetracosanoylamino] 10- octadecene- 1,3,4- triol ( 1 ), ( 2 S, 3 S, 4 R ) -2- tetracosanoylamino- 1,3,4- octadecanetriol ( 2 ), daucosterol (3), swertish (4), benzoic acid (5), salicylic acid (6), loliolide (7), thymine (8),uracil(9), (23 Z)-9, 19-cycloart-23-ene-3β, 25-diol (10), (20S, 22E, 24R )-5α, 8α- epidioxy-ergosta-6,22-diene-3β-ol (11),2,3- dihydroxypropyl hexadecoate (12), soya-cerebroside (13) and (22 E, 24 S)-24-methyl-5α-cholesta-7,22-diene-3β, 5α, 6β-triol(14).
