Variacions en els components bioquímics del romaní (Rosmarinus Officinalis L.) al llarg de la floració Authors R. Segarra Ramon Clotet i Ballús Abstract Samples of rosemary were picked up during the spring bloom period and the following parameters were analyzed: dry matter, production of organic dry matter, reducing sugars, nitrogen, chlorogenic acid, ether and alcoholic extracts, content of essential oils and their composition. The results show a variation of the biochemical components of rosemary during its biological cycle. None of the analyzed parameters has kept constant during the studied period, just a relative constant production of organic dry matter has been noticed. A comparative study of all the results allows to distinguish between two big groups of maximums. The first one is made up of the basic biochemical components, such as sugars and nitrogen which show a maximum between the 7th and 9th week. On the other hand between the 9th and 13rd week appear the maximums of all the other parameters: essential oils, alcoholic extract, chlorogenic acid, total and non-volatile ether extract. The composition of the essential oils shows off that between the 9th and 1 1 st week, the content of high volatility components is maximum. Downloads Download data is not yet available.
