Chemical composition and antifungal activity of the fruit oil of zanthoxylum bungeanum maxim.(Rutaceae) from china / Youwen Gong in The journal of essential oil research, Vol. 21 N° 2+ supplément vol.20 (Mars/Avril 2009+ supplément 2008)

Terpinen-4-ol (19.7%), 1,8-cineole (16.0%), p-cymene (7.9%), γ-terpinene (7.3%) and α-terpineol (7.2%) were the major compounds of the 35 identified components. The antifungal activity of the oil against 15 plant pathogenic fungi was assayed by the mycelial growth inhibition method and the values of median inhibition concentration (IC50) were below 1.0 mg/mL. The results showed that the oil had a broad spectrum of inhibitory activity against the tested fungi. The volatile components of the oil also obviously inhibited the mycelial growth of Rhizoctonia solani and Rhizoctonia cerealis. These results indicate that Z. bungeanum oil could be a source of antifungal ingredients for plant disease control especially applied in fruit and vegetable preservation.

Chemical composition and antimicrobial activity of the flower oil of russowia sogdiana (Bunge) B. fedtsch. (Asteraceae) from China / Manliang Tan in The journal of essential oil research, Vol. 19 N°2 (Mars-Avril 2007) 

Public ISBD [article]  in The journal of essential oil research > Vol. 19 N°2 (Mars-Avril 2007) . - pp. 197-200 Titre : Chemical composition and antimicrobial activity of the flower oil of russowia sogdiana (Bunge) B. fedtsch. (Asteraceae) from China Type de document : texte imprimé Auteurs : Manliang Tan, Auteur ; Ligang Zhou, Auteur ; Meng Qin, Auteur Année de publication : 2007 Article en page(s) : pp. 197-200 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Russowia  sogdiana  Asteraceae  Essential  oil  composition  limonene  Antimicrobial  activity Résumé : An essential oil, which was obtained by water distillation from Russowia sogdiana (Bunge) B. Fedtsch. flowers, was analyzed by GC and GC/MS. The main constituents were identified as limonene (15.9%), trans-α-bergamotene (5.6%), salvial-4(14)-en-1-one (3.8%), carvone (3.6%), p-cymene (3.6%), trans -carveol (3.2%). Thirty-two components were separated and identified which accounted for over 62.1% of the total essential oil. The antimicrobial activity of R. sogdiana oil was studied using broth dilution test on seven bacterial strains, using mycelial growth test on three fungal strains. The oil exhibited a broad spectrum antibacterial activity against Gram-positive (Bacillussubtilis, Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli, Erwinia carotovora ssp. carotovora, Pseudomonas lachrymans, Xanthomonas vesicatoria, Agrobacterium tumefaciens) with minimum inhibitory concentration (MIC) values ranging from 0.2 mg/mL to 0.8 mg/mL. The oil also showed an important antifungal activity against fruit pathogenic fungi Glomerella cingulata, Botryodiplodia theobromea and Venturia pirina. Maximum antifungal activity was observed against G. cingulata mycelial growth which percentage inhibition was 51.8% at concentration of 100 μg/mL.
