Bibliographical summary on high performance liquid chromatography of lipids : IV 1985-1994 By

En el presente compendio, y siguiendo la tradición empezada por K. Aitzetmüller con la recopilación de los trabajos aparecidos desde 1961 y continuada posteriormente por los presentes autores a partir de 1975, se presenta un estudio bibliométrico sobre las publicaciones aparecidas entre los años reseñados en el título; como base de datos se ha tomado el Chem. Abstr. fundamentalmente. En este estudio se indican los temas que más han sido tratados por los investigadores y las revistas más o menos especializadas en los mismos. El número total de trabajos revisados asciende a 1680, superior en 680 al número de trabajos aparecidos en la década anterior. Se hace especial hincapié en las reviews aparecidos. (Inglés).

number of references appearing (680 more than in the previous decade), it was thought inappropriate to detail all in the present summary, but to classify them, relating the various common topics with the years in which they were published and with the journals in which they appeared.With this aim, a thesaurus of key words has been built up (Table I), which enables all the references to be classified and which basically coincides with the previously published articles (2) (3) (4).
A first analysis of this database is given in Diagram 1, and shows how the topics published more often during this period are the same as those of the previous decade.Only those relating to the vitamins have a similar percentage (21.6 against 21,3%), which shows a similar interest for the topic on the part of the different researchers; the remainder have decreased in percentage although the absolute number of works has increased.
Diagram 2 shows the number of works by year.It should be noted that there is no obvious trend for the annual number of articles to increase continually, and it seems that since 1991 these topics are of less interest, measured as percentage of annual articles.
Diagram 3 shows the number of works by journal.It can be seen that most of the journals published a single work during the decade, and only a very few published more than 10 works relating to the topic, although 42% of the works published are from those journals that published more than 10 works on HPLC of lipids.Naturally, of all the journals, the most outstanding, for the high number of works published, is J. Chromatogr., which is responsible for 21,5% of all the articles appearing during the decade.Diagram 4 shows the annual distribution of the articles from J. Chromatogr.It can be seen that this distribution is more or less uniform.Diagram 5 shows the distribution of the works appearing in that journal, by topic.This  Diagram 5 Distribution by key word of the articles appearing in J. Chromatogr.
distribution coincides in the main with the general one of Diagram 1, indicating that J. Chromatogr.includes a large number of articles that represent, to a high degree, the research being undertaken world-wide on these topics.
Table II shows those journals that have published 10 or more works on HPLC of lipids during the decade, listing them by year and showing the topics published in accord with the thesaurus of key words given in Table I.The works appearing in J. Chromatogr.are not included, as they have been commented on above.
Table III shows all the reviews appearing during the decade; the authors consider that these reviews may be of interest to researchers who are beginning in HPLC of lipids, and their inclusion here, gathered together, may help when searching the specialised bibliography.
