The   aim   of   this   work  was   to   study   the   fatty  acid   composition   and   proximate   analysis,  including   total proteins,  dry  matter,  total  phenol  levels,   antioxidants   and   antiradical  activities  of   clary  sage  (Salvia   sclarea L.)  seeds   harvested   in   five   consecutive   years,   from  2006  to   2010.   Firstly,  the   dry  matter,  oil,  protein  and
fatty  acid   composition   of   the   clary  sage  seeds   were  determined.   The   dry  matter,  oil  and   protein  content of   the   clary  sage  seed  samples   varied  between  97.64   and   98.35,   23.83   and   29.34,   and   21.97   and   22.96%, respectively.  Secondly,   the   fatty  acid   compositions  in   the   oil  and   the   bioactive  properties   in   the   extract
were  investigated.  Polyunsaturated   fatty  acids  were  the   most  abundant   fatty  acids  in   the   clary  sage. The   -linolenic,   oleic  and   linoleic   acid   contents  of   the   sage  oils   changed  from  50.04   to   53.69%;   20.10 to   22.97%;   15.54   to   18.06%,  respectively   according   to   year.  The   total  phenolic  content,   antioxidant  and antiradical  activities  of   the   sage  seeds   were  determined  in   the   range   of   7.71–13.21  mg  GAE/g   dry  extract,
50.45–74.04   (mg   AAE/g   dry  extract)   and   13.14–21.21%  respectively.  Each  of   the   investigated   parameters of   the   sage  seeds   was   significantly   affected   by  the   harvesting  year.  Consequently,   clary  sage  seeds   are rich   in   fatty  acids  and   contained   high  levels   of   antioxidant  and   antiradical  activities  making  them   ideal for   use   as  nutraceuticals.

Secondly, the fatty acid compositions in the oil and the bioactive properties in the extract were investigated. Polyunsaturated fatty acids were the most abundant fatty acids in the clary sage. The alpha-linolenic, oleic and linoleic acid contents of the sage oils changed from 50.04 to 53.69%; 20.10 to 22.97%; 15.54 to 18.06%, respectively according to year. The total phenolic content, antioxidant and antiradical activities of the sage seeds were determined in the range of 7.71-13.21 mg GAE/g dry extract, 50.45-74.04 (mg AAE/g dry extract) and 13.14-21.21% respectively. Each of the investigated parameters of the sage seeds was significantly affected by the harvesting year. Consequently, clary sage seeds are rich in fatty acids and contained high levels of antioxidant and antiradical activities making them ideal for use as nutraceuticals. (C) 2012 Elsevier B.V.
