Two novel alkaloids were identified as (E)-N-(4-3,4-dihydroxy-6-(hydroxymethyl)-5-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)tetrahydro-2H-pyran-2-yl)oxy)-2,5-dihydroxyphenyl)-3-(4-hydroxyphenyl)acrylamide , named Oleracrylimide D, (E)-N-(4-3,4-dihydroxy-6-(hydroxymethyl)-5-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)tetrahydro-2H-pyran-2-yl)oxy)-2,5-dihydroxyphenyl)-3-(4-hydroxy-3-methoxyphenyl)acrylamide , named Oleracrylimide E, isolated from L. The structures were identified by spectroscopic methods, including 1D NMR, 2D NMR, and UHPLC-ESI-QTOF/MS methods, also, the anti-inflammatory bioactivities of the compounds were studied by ELISA method.
两种新型生物碱被鉴定为（E）-N-（4-3,4-二羟基-6-（羟甲基）-5-3,4,5-三羟基-6-（羟甲基）四氢-2H-吡喃-2-基）氧基）四氢-2H-吡喃-2-基）氧基）-2,5-二羟基苯基）-3-（4-羟基苯基）丙烯酰胺，命名为Oleracrylimide D，（E）-N-（4-3,4-二羟基-6-（羟甲基）-5-3,4,5-三羟基-6-（羟甲基）四氢-2H-吡喃-2-基）氧基）四氢-2H-吡喃-2-基）氧基）-2,5-二羟基苯基）-3-（4-羟基-3-甲氧基苯基）丙烯酰胺，命名为Oleracrylimide E，从L.中分离得到。通过包括一维核磁共振、二维核磁共振和超高效液相色谱-电喷雾电离-四极杆飞行时间质谱等光谱方法鉴定了其结构，此外，还通过酶联免疫吸附测定法研究了这些化合物的抗炎生物活性。
