“…Similarly, Müller‐Riebau et al found that L. nobilis oil only showed a slight effect against Fusarium moniliforme and Phytophthora capsici , and even had no effect against Rhizoctonia solani and Sclerotinia sclerotiorum at 1000 µL mL −1 . In these reports, the main components of L. nobilis oil were reported as 1,8‐cineole, sabinene, α ‐pinene, linalool, α ‐terpinyl acetate and β ‐pinene, which were the important components for inhibiting the growth of pathogens . However, in our study, we found that the main components of our tested essential oil were quite different, with the conjecture that the production area and the environment influenced the components of the essential oil.…”

“…The biocidal activity of this plant has been associated with its high content in umbellulone (39%), which has been shown to be toxic when fed to laboratory mice. 11 Therefore, the high content of umbellulone in aerial parts of P. bahiana might be responsible for its reputed effectiveness to kill fleas.…”

A espécie Poiretia bahiana, popularmente conhecida como arrudinha, arruda da serra ou arruda brava, tem uma ocorrência restrita aos campos rupestres da Chapada Diamantina, BA. Suas partes aéreas apresentam um aroma pungente e é usada pelo povo do local no controle de infestações por pulgas e no tratamento de hemorróidas, dores nas articulações e sinusite. Neste trabalho, relatamos a composição dos óleos voláteis obtidos das partes aéreas de cinco espécimes e do óleo volátil obtido dos frutos de um espécime de P. bahiana, os quais foram coletados em diferentes regiões da Chapada Diamantina. Nos óleos voláteis que foram analisados por CG-FID e CG-EM foram identificados vinte e nove componentes sendo que os dois principais foram a umbelulona, em concentrações entre 55,0% e 75,3%, e sabineno, em concentrações entre 10,3% e 25,2%. O óleo das partes aéreas de um espécime e o óleo dos frutos de outro espécime foram avaliados quanto às suas propriedades antimicrobianas contra seis bactérias, duas leveduras e cinco fungos filamentosos pelos ensaios de difusão em ágar e microdiluição. Os óleos exibiram atividade contra Escherichia coli, Salmonella choleraesuis, Proteus mirabilis, Staphylococcus aureus, Staphylococcus aureus resistente à meticilina (MRSA), Candida albicans, Cryptococcus neoformans, Cladosporium herbarum, Microsporum canis, Trichophyton rubrum e foram inativos contra Pseudomonas aeruginosa, Aspergillus fumigatus e Penicillium notatum. A toxicidade do óleo das partes aéreas foi determinada contra Artemia salina apresentando uma LC 50 de 459,03 mg mL -1 .Poiretia bahiana known as "arrudinha", "arruda da serra" or "arruda brava", has its occurrence restricted to the rock fields (campo rupestre) areas in Chapada Diamantina, Bahia, northeastern region of Brazil. Its aerial parts present a pungent smell and have been used by local communities as fumigant for the control of infestation of fleas and in the treatment of hemorrhoids, articulations pain and sinusitis. This work reports the composition of the volatile oils from aerial parts of five specimens and of the essential oil from the fruits of one specimen of Poiretia bahiana that were harvested in four different places of Chapada Diamantina. Twenty nine components were identified from the oils analyzed by GC-FID and GC-MS. Umbellulone, in concentrations between 55.0% and 75.3% and sabinene, in concentrations between 10.3% and 25.2% are the major components. The oil from the aerial parts of one specimen and the oil of fruits of another specimen had their antimicrobial properties evaluated against six bacteria, two yeasts and five filamentous fungi by the agar diffusion method and microdilution assay. The in vitro results demonstrated that these essential oils exhibit antimicrobial activity against Escherichia coli, Salmonella choleraesuis, Proteus mirabilis, Staphylococcus aureus, methicilin resistant Staphylococcus aureus (MRSA), Candida albicans, Cryptococcus neoformans, Cladosporium herbarum, Microsporum canis, Trichophyton rubrum and are inactive against Pse...

“…Nevertheless, the odor, flavor, and chemical compositions of these leaves are distinguishably different from the true bay leaf. The essential oils of the Californian bay leaf contain a volatile monoterpene, umbellulone, as a major component present solely in this plant species [12]. This toxic compound can cause a severe headache, sinus irritation, sneezing, and even unconsciousness in some sensitive individuals [13].…”

Correct identification of the true bay leaf () and its substitutes is important not only for the quality control of the products, but also for the safety of the consumers. is often substituted or confused with other species, such as, and In the present study, the potential of gas chromatography combined with quadrupole time-of-flight mass spectrometry for the profiling of various bay leaf products was evaluated for the first time. Thirty-nine authenticated samples representing the true bay leaf and the four commonly substituted species were analyzed. An automatic feature extraction algorithm was applied for data mining and pretreatment in order to identify the most characteristic compounds representing different bay leaf groups. This set of data was employed to construct a sample class prediction model based on stepwise reduction of data dimensionality followed by principal component analysis and partial least squares discriminant analysis. The statistical model, with demonstrated excellent accuracies in recognition and prediction abilities, enabled the correct classification of commercial samples including complex mixtures and essential oils. In addition, in-house developed personal compound database and library with retention time locking offered the advantage of combining retention time matching with accurate mass matching, resulting in high confidence of compound identification for each bay leaf subgroup. At least three marker compounds were identified for each bay leaf species that could be used to discriminate among them.
