Four previously undescribed erythrinan alkaloids, 8α-acetonylerythristemine, 8α-acetonylerysotrine, 10β-hydroxy-11β-methoxyerysotramidine and 3-epierysotrine, one undescribed pyrrolidine derivative, S-1-(4-hydroxy-3-methoxyphenethyl)-5-hydroxy pyrrolidin-2-one, and one undescribed amide, N-(3-hydroxy-4-methoxyphenethyl)-4-hydroxylbutanamide, along with thirteen known alkaloids were isolated from the stem barks of Erythrina strica Roxb. (Leguminosae). Their structures were identified by extensive analysis of physical, spectroscopic and spectrometric data. It's very interesting that the coexistence of 3-methoxytyramine, erythrinarbine, S-1-(4-hydroxy-3-methoxyphenethyl)-5-hydroxy pyrrolidin-2-one and N-(3-hydroxy-4-methoxyphenethyl)-4-hydroxylbutanamide that may be closely related in biosynthesis, supports the hypothetical biogenetic pathway of pyrrolo [2,1-a]isoquinoline alkaloids.

刺桐茎皮中的生物碱

四种先前未描述的赤藓糖苷生物碱、8α-丙酮基赤藓酮胺、8α-丙酮基赤霉胺、10β-羟基-11β-甲氧基赤霉脒和 3-epierysotrine、一种未描述的吡咯烷衍生物、S-1-(4-羟基-3-甲氧基苯乙基)-5-羟基苯胺从 Erythrina strica Roxb 的茎皮中分离出 2-one 和一种未描述的酰胺、N-(3-羟基-4-甲氧基苯乙基)-4-羟基丁酰胺以及 13 种已知的生物碱。（豆科）。它们的结构是通过对物理、光谱和光谱数据的广泛分析来确定的。很有意思的是，3-甲氧基酪胺、erythrinarbine、S-1-(4-羟基-3-甲氧基苯乙基)-5-羟基吡咯烷-2-one和N-(3-羟基-4-甲氧基苯乙基)-4-共存可能与生物合成密切相关的羟基丁酰胺，
