ABSTRACT

The phenomenon of scientific retraction is a shameful act for the scientific community, but a necessity to maintain the purity of science. The two main causes for retractions include plagiarism and research misconduct. The post retraction citation of articles is again a repetition of inappropriateness. Hence the editorial, peer review policies should be revised and the retractions should be publicized more to avoid the citation of the invalid literature. Also, the scientific readership has a responsibility to evaluate the scientific validity of published studies.


El fenómeno de la retractación científica constituye una vergüenza para la comunidad científica, pero es necesario para mantener la pureza de la ciencia. Las dos causas principales de retractación son el plagio y faltas en la conducta de investigación. La citación de artículos posterior a su retractación es, de nuevo, una repetición inapropiada. Por lo tanto, la editorial y las normas de evaluación por pares debieran revisarse y las retractaciones publicarse más para evitar las citaciones de literatura inválida. También los lectores científicos tienen la responsabilidad de evaluar la validez científica de los estudios publicados.

Daí porque o editorial e a política de revisão por pares devem ser revistas e as retratações deveriam ser mais divulgadas para evitar uma citação inválida da literatura. Ademais, o revisor científico tem uma responsabilidade de avaliar a validade científica dos estudos publicados.

ABSTRACT

Centella asiatica is a valuable medicinal plant with abundant amount of pharmaceutically useful compounds; however, it is important to know the proper physiological age for drug formulation. In the present study, smaller to larger thirteen groups of Centella asiatica leaves were evaluated for growth, chlorophyll content and antioxidant activity. The growth was measured in the terms of leaf area, fresh and dry weights and water content. Maximum antioxidant activity was found in third size group of the leaf which was further analyzed for phenolics in RP-HPLC. The probable role of these phenols in antioxidant activities is discussed.
