Essential oil from two populations of Echinodorus grandiflorus (Cham. & Schltdl.) Micheli (Chapéu de couro) Anais da ABC (AABC)
Pimenta,Daniel S.; Figueiredo,Maria Raquel; Kaplan,Maria Auxiliadora C..
Analysis by Gas Chromatography and Gas Chromatography/Mass Spectrometry of the essential oils obtained from leaves of Echinodorus grandiflorus ("Chapéu de couro") from two different populations (Big Leaves and Small Leaves), collected monthly between September 1998 and December 1999 revealed 17 components. Phytol was the major constituent for both populations. The main sesquiterpene representatives are (E)-caryophyllene, alpha-humulene and (E)-nerolidol.

Plumbagin quantification in roots of Plumbago scandens L. obtained by different extraction techniques Anais da ABC (AABC)
Paiva,Selma R. de; Lima,Lucilene A.; Figueiredo,Maria Raquel; Kaplan,Maria Auxiliadora C..
The Plumbago genus belongs to the Plumbaginaceae family and it is known due to its variety of biological uses, most of them attributed to the presence of naphthoquinones. Plumbagin is a naturally occurring naphthoquinone that can be obtained from roots of Plumbago scandens L. In order to find out the better technique for plumbagin extraction, were applied: static maceration, dynamic maceration, with assistance of ultrasonic waves and in Soxhlet apparatus. Four compounds were qualitatively detected in all extracts: the naphthoquinones plumbagin and epi-isoshinanolone, palmitic acid and sitosterol. Plumbagin was always the major component in all analyzed extracts and it was quantitatively determined by gas chromatograph coupled with mass spectrometer....

Chemical composition fluctuations in roots of Plumbago scandens L. in relation to floral development Anais da ABC (AABC)
Paiva,Selma R.; Lima,Lucilene A.; Figueiredo,Maria Raquel; Kaplan,Maria Auxiliadora C..
Plumbago scandens L. is a Brazilian tropical/subtropical species that occurs along the coast. Chemically it is mainly represented by naphthoquinones, flavonoids, terpenoids and steroids. The aim of the present work is to study quantitative changes in the root metabolic production of Plumbago scandens during different physiologic developmental stages relative to floration. The results indicated the presence of four substances in the extracts: plumbagin, epi-isoshinanolone, palmitic acid and sitosterol, independent on developmental stage. The naphthoquinone plumbagin has always showed to be the major component of all extracts. Naphthoquinones exhibited their highest content during floration, while the content of the two others components decreased during...

Chemosystematic aspects of polyisoprenylated benzophenones from the genus Clusia Anais da ABC (AABC)
Anholeti,Maria Carolina; Paiva,Selma R. de; Figueiredo,Maria Raquel; Kaplan,Maria Auxiliadora C..
Benzophenone derivatives are special metabolites that arouse great scientific interest. The Clusiaceae family is known for producing large amounts of benzophenone derivatives with several isoprene residues on their structures, which are responsible for the observed complexity and structural variety in this class of substances, and also contribute to their biological activities. Clusia is an important genus belonging to Clusiaceae, with 55 different polyisoprenylated benzophenones identified so far. These substances were analyzed from biosynthetic and chemosystematic points of view, allowing the determination of characteristics regarding their production, accumulation and distribution within this genus. Polyisoprenylated benzophenones found in Clusiashowed...
