Description

A pair of new guaiane-type sesquiterpene tautomers (1) was isolated from rhizomes of Acorus calamus. Meanwhile, three pairs of known compounds, including a pair of dihydroflavone glycoside tautomers (2), a pair of 4-hydroxybenzoic acid ester glycoside tautomers (3), as well as a pair of secoiridoid glycoside tautomers (4) were isolated from fruits of Cornus officinalis. Their structures were elucidated by extensive spectroscopic and computational methods. Furthermore, the tautomeric mechanisms were discussed.

Translated Description (Arabic)

تم عزل زوج من tautomers sesquiterpene من نوع guaiane الجديد (1) من جذور Acorus calamus. وفي الوقت نفسه، تم عزل ثلاثة أزواج من المركبات المعروفة، بما في ذلك زوج من tautomers جليكوسيد ثنائي هيدروفلافون (2)، وزوج من tautomers جليكوسيد إستر حمض 4 - hydroxybenzoic (3)، وكذلك زوج من tautomers جليكوسيد secoiridoid (4) من ثمار Cornus officinalis. تم توضيح هياكلها من خلال طرق طيفية وحسابية واسعة النطاق. علاوة على ذلك، نوقشت آليات tautomeric.

Pendant ce temps, trois paires de composés connus, dont une paire de tautomères de glycoside de dihydroflavone (2), une paire de tautomères de glycoside d'ester d'acide 4-hydroxybenzoïque (3), ainsi qu'une paire de tautomères de glycoside de sécoiridoïde (4) ont été isolés à partir de fruits de Cornus officinalis. Leurs structures ont été élucidées par de vastes méthodes spectroscopiques et informatiques. De plus, les mécanismes tautomères ont été discutés.

Se aisló un par de nuevos tautómeros sesquiterpénicos de tipo guaiane (1) de rizomas de Acorus calamus. Mientras tanto, se aislaron tres pares de compuestos conocidos, incluido un par de tautómeros de glicósido de dihidroflavona (2), un par de tautómeros de glicósido de éster de ácido 4-hidroxibenzoico (3), así como un par de tautómeros de glicósido secoiridoide (4) de frutos de Cornus officinalis. Sus estructuras se dilucidaron mediante extensos métodos espectroscópicos y computacionales. Además, se discutieron los mecanismos tautoméricos.
