Plants release volatiles in response to caterpillar feeding that attract natural enemies of the herbivores, a tri-trophic interaction which has been considered an indirect plant defence against herbivores. The caterpillar-induced plant volatiles have been reported to repel or attract conspecific adult herbivores. To date however, no volatile signals that either repel or attract conspecific adul...

This study investigated the chemical composition, and antimicrobial and anti-wood-decay fungal activities of the essential oil isolated from the leaf of endemic Machilus zuihoensis Hayata, Lauraceae, of Taiwan. The essential oil from the fresh leaves of M. zuihoensis was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. A total of 104 compoun...

Abstract Plants represent a rich repository of taxonomically restricted, yet chemically diverse, secondary metabolites that are synthesised via specific metabolic pathways. Enzyme specificity and biosynthetic gene clustering the bottleneck metabolite evolution. As economically important food crops, grape, strawberry, olive produce many pharmaceutically molecules; however, their pathways remain ...

Indonesian people had long used plants as traditional medicine. In addition to maintaining health, medicine was in great demand and prevents disease. We often encounter syzygium polyanthum leaves a complement tamarind pepes, which were believed act preservative. This study aimed determine qualitatively bay leaf extract an antimicrobial, Salmonella typhi. Methanol extraction of polyantum would b...

Pogostemon heyneanus Benth is a prominent and well-known medicinal plant Asian countries that recommended with high value traditional practices, Ayurvedic treatments folkloric use. It also k...

Abstract In grape berries ( Vitis vinifera L.), sesquiterpenes are mainly accumulated as hydrocarbons in the epicuticular wax layer of grapes, whereas monoterpenes, which predominantly present alcohols, glycosylated and stored glycosides vacuoles berry cells. this study, extensive analysis hydrolysates by means comprehensive two-dimensional gas chromatography–time-of-flight–mass spectrometry de...
