This article has been retracted at the request of the Co-Authors with the Editor-in-Chief approval.

The Journal of Pharmacy & Pharmacognosy Research (JPPRes) retracts the article “Isoflavone and triterpenoid isolated from an endemic plant Genista microcephala Coss et Dur.” by lhem Bouakaz et al., which was published in 2015.

Against the policy agreed to by the JPPRes in relation to corresponding author, this paper was submitted for publication without the consent of two of the authors (G. Massiot and H. Haba). One of the conditions of submission of a paper for publication in JPPRes is that as corresponding author declares explicitly that “all authors are aware that study has been submitted to Journal of Pharmacy & Pharmacognosy Research (JPPRes)”. This article has been retracted as its publication violates this policy.

As such this article represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of this journal because this inconvenient was not detected during the submission process.

Abstract

Context: Genista microcephala Coss et Dur is a plant that grows in northern of Algeria. The Genista species show interesting biological properties.

Aims: To study phytochemically of the aerial parts of G. microcephala and search new compounds with pharmacological interest.

Methods: Aerial parts of G. microcephala were extracted using chloroform. The extract was purified by several chromatography processes. Isolated compounds were analyzed by the usual spectroscopic methods and 2D NMR technics.

Results: From the chloroformic extract of the air parts of Genista microcephala (Leguminosae) two known components were obtained. The structures of these compounds were oleanolic acid (1), alpinum isoflavone (2) elucidated by the usual spectroscopic methods and 2D NMR technics and by comparison with literature data.

Conclusions: Two known components were obtained from the chloroformic extract of the air parts of Genista microcephala but they have not previously been reported from this species.

Keywords: Genista microcephala; isoflavone; Leguminosae; triterpenoid.

Resumen

Contexto: Genista microcephala Coss et Dur. es una planta que crece en el norte de Argelia. Las especies de Genista muestran propiedades biológicas interesantes.

Objetivos: Estudias desde el punto de vista fitoquímico las partes aéreas de G. microcephala y buscar nuevos compuestos que tengan interés farmacológico.

Métodos: Las partes aéreas de G. microcephala fueron extraidas con cloroformo. El extracto fue purificado mediante varios procesos cromatográficos. Los compuestos aislados fueron analizados por métodos espectroscópicos usuales y técnicas de 2D RMN.

Resultados: Se obtuvieron dos compuestos conocidos del extracto clorofórmico de las partes aéreas de Genista microcephala (Leguminosae). Las estructuras de estos compuestos fueron ácido oleanólico (1) y alpinum isoflavona (2) elucidadas por métodos espectroscópicos usuales y técnicas de 2D RMN y la comparación con datos de la literatura.

Conclusiones: Se obtuvieron dos compuestos conocidos en el extracto clorofórmico de las partes aéreas de G. microcephala pero estos son reportados por primera vez para esta especie.

Palabras Clave: Genista microcephala; isoflavona; Leguminosae; triterpenoide.
