“…Plants of the Apiaceae family usually have terpenes, another important chemical group involved in plantinsect interactions. Terpenes, together with moisture, nitrogen, phenolics and toughness have a significant role in the relationships between two leguminous genera (Copaifera and Hymenaea) and their main lepidopteran herbivores in a cerrado region (Langenheim et al, 1986a(Langenheim et al, , 1986bMacedo & Langenheim, 1989a, 1989b.…”

Susceptibility of Didymopanax vinosum (Apiaceae) to insect herbivores was investigated in three sites of a cerrado mosaic -composed of campo cerrado (a grassland with scattered trees and shrubs), cerradão (a tall woodland) and cerrado sensu stricto (intermediate between the two) -situated in Cerrado Pé-deGigante, Santa Rita do Passa Quatro, SP, Brazil. We also examined the relationship of folivory with the composition and abundance of the insect herbivore fauna, and with several nutritional and defensive plant characteristics (water, nitrogen, cellulose, lignin, tannin leaf contents, and leaf toughness). We collected insects associated with D. vinosum every month, and we measured leaf damage every three months. In general, the annual folivory differed among sites. It reached the highest rates in site 1 and site 3: 7.33 and 8.5 percent, respectively. Only 1.32 percent of annual folivory was observed in site 2. These levels resulted from the higher abundance, in sites 1 and 3, of the thrips Liothrips didymopanacis (Phlaeothripidae), the most abundant herbivore sampled, responsible for more than 90 percent of the observed damage. However, no significant relationship was found between insect activity and the chemical and physical composition of the leaves. Our findings suggest that, at least in this species, other chemical compounds or variables related to plant apparency and resource availability to herbivores (e.g. plant architecture) might play a more decisive role in the spatial variation of folivory than the nutritional and defensive traits that were analyzed.Keywords: cerrado, Didymopanax vinosum, folivory, herbivory, plant defenses. RESUMO Folivoria por insetos em Didymopanax vinosum (Apiaceae) em um mosaico de vegetação no cerrado brasileiroA susceptibilidade de Didymopanax vinosum (Apiaceae) a insetos herbívoros foi investigada em três localidades de um mosaico de cerrado -composto de campo cerrado, cerrado sensu stricto e cerradão -localizado no Cerrado Pé-de-Gigante, Santa Rita do Passa Quatro, SP, Brasil. Nosso objetivo foi também relacionar a folivoria com a composição e abundância da fauna de insetos herbívoros, e com várias características nutritivas e defensivas da planta (conteúdo foliar de água, nitrogênio, celulose, lignina, taninos e dureza foliar). Para tanto, coletamos mensalmente os insetos associados a D. vinosum e a cada três meses medimos as injúrias foliares. De modo geral, a herbivoria anual variou entre as localidades. Os maiores valores foram encontrados em plantas da localidade 1 e localidade 3: 7,33 e 8,5 por cento, aproximadamente, contra apenas 1,32 por cento na localidade 2. Esses níveis são resultado da maior abundância, nas localidades 1 e 3, do trips Liothrips didymopanacis (Phlaeothripidae), o principal herbívoro amostrado, responsável por mais de 90% das injúrias observadas. Entretanto, não se encontrou relação entre a atividade desses insetos e a composição química e física das folhas. Nossos resultados indicam que, ao menos para esta espécie, outros compostos químico...

“…While numerous studies focused on the accumulation and varietal differentiation of monoterpenes in grapevine, much less is known about the chemistry and biochemistry of sesquiterpenes in this economically important plant. In several studies the developmentally regulated accumulation of sesquiterpenes in different plant species as well as their various functions from signalling infochemicals to herbivore defence have been investigated . However, in grapevine only little is known about the developmental regulation and the influence of biotic or abiotic factors on sesquiterpene accumulation.…”

To investigate the profiles of sesquiterpene hydrocarbons in grape berries at different developmental stages several cultivars of Vitis vinifera (Gewürztraminer, Riesling, Yellow Muscat, Shiraz, Lemberger, Cabernet Sauvignon) were analysed during ripening. Therefore, HS‐SPME‐GC‐MS measurements were performed with intact grape berries. The measurements demonstrated that grapes emit numerous sesquiterpene hydrocarbons and that the sesquiterpene profile exhibits a characteristic profile, depending on the variety and the developmental stage. In particular, bicylic sesquiterpenes with a cadinane backbone increased during ripening, while acyclic sesquiterpenes such as (E,E)‐α‐farnesene decreased, except for Gewürztraminer which shows increasing amounts of acyclic sesquiterpenes towards harvest. Furthermore, the profiles of the emitted sesquiterpenes differed significantly. In particular, Gewürztraminer possessed remarkably high amounts of (E,E)‐α‐farnesene, (3E,6Z)‐α‐farnesene and (E,E)‐methylfarnesoate, while the sesquiterpene profiles of Riesling, Lemberger, Shiraz and Yellow Muscat were dominated by bi‐ and polycyclic sesquiterpenes. Cabernet Sauvignon showed only minor profile changes during ripening and its comparatively low sesquiterpene hydrocarbon amounts were dominated by (E)‐β‐caryophyllene, α‐humulene and an unidentified sesquiterpene.

Purpose: to demonstrate the effect of matrix microparticles of Copaifera langsdorffii (aerial parts of copaiba), aiming to evaluate the discussions and results of the works that demonstrate Its function on the kidneys as well as its effectiveness. Methods:A bibliographic study was carried out by consulting public online databases of patents, such as the United States Patent and Trademark office, World Intellectual Property Organization and the National Intellectual Property Institute; The following keywords were used: copaiba oil, renal function, kidney, kidney stones, matrix microparticles Copaifera langsdorffii and lithiasis. In this study were included patents of invention, innovations and utility models in the period from January 2007 to May 2016. Results:One patent register was included regarding a method for obtaining microparticles and compounds, having antilithiasic, analgesic, antispasmodic, anti-inflammatory, diuretic and antiseptic activity. Conclusion:The patent registry survey demonstrates the possibility of beneficial action of matrix microparticles Copaifera langsdorffii on renal physiology, acting as antilithiasis and even with diuretic properties, thus opening up new possibilities of research of this substance on renal physiology.
