Dantong Zheng, Chongxing Huang, Haohe Huang, Yuan Zhao, Muhammad Rafiullah Khan, Hui Zhao, Lijie Huang
AbstractCurcumin is a plant‐derived polyphenolic active substance with
broad‐spectrum antibacterial properties. Curcumin blocks bacterial growth owing
to its structural characteristics and the generation of antioxidation products.
Curcumin can inhibit bacterial virulence factors, inhibit bacterial biofilm
formation and prevent bacterial adhesion to host receptors through the bacterial
quorum sensi... hiện toàn bộ
Chemical Composition and Antibacterial Activity of Essential Oils from Different Parts of Litsea cubeba Tập 7 Số 1 - Trang 229-235 - 2010
Hongwu Wang, Yanqing Liu
AbstractThe composition of the essential oils obtained by hydrodistillation of
different parts of Litsea cubeba, including roots, stems, leaves, alabastra
(flower buds), flowers, and fruits, were investigated by GC (RI) and GC/MS. The
antimicrobial activity of the oils was assessed with disc diffusion and
microbroth dilution assays. The results showed large variations in the
composition among the ... hiện toàn bộ

AbstractIn an effort to develop local productions of aromatic and medicinal
plants, a comprehensive assessment of the composition and biological activities
of the essential oils (EOs) extracted from the aerial flowering parts of wild
growing Lavandula stoechas L. collected from eleven different locations in
northern Algeria was performed. The oils were characterized by GC‐FID and GC/MS
analyses, a... hiện toàn bộ
Terpenoid Compositions, and Antioxidant and Antimicrobial Properties of the Rhizome Essential Oils of Different Hedychium Species Tập 5 Số 2 - Trang 299-309 - 2008
Sushil Joshi, C.S. Chanotiya, Garima Agarwal, Om Prakash, A.K. Pant, C. S. Mathela
AbstractA phytochemical study of the rhizome essential oils of four different
Hedychium species was performed by means of GC and GC/MS analyses. H. ellipticum
mainly contained 1,8‐cineole, sabinene, and terpin‐4‐ol, while H. aurantiacum
possessed terpin‐4‐ol, para‐cymene, and bornyl acetate as the major entities.
Similarly, trans‐meta‐mentha‐2,8‐diene and linalool were noticed in H.

Antimicrobial and Cytotoxic Activities of Neolignans from Magnolia officinalis Tập 1 Số 3 - Trang 530-537 - 2004
Wan‐Jr Syu, Chien‐Chang Shen, Jang‐Jih Lu, Gum‐Hee Lee, Changming Sun
AbstractIn the light of the steady increase of infections related to
vancomycin‐resistant enterococci (VRE) and methicillin‐resistant Staphylococcus
aureus (MRSA), the medicinal plant Magnolia officinalis was subjected to
bioassay‐directed fractionation, which led to the isolation of the known
neolignans piperitylmagnolol (1), magnolol (2), and honokiol (3) from the MeOH
extract. In broth‐microdil... hiện toàn bộ
Antifungal Activity of Alkaloids from the Seeds of Chimonanthus praecox Tập 6 Số 6 - Trang 838-845 - 2009

Abstractmagnified imageTwo alkaloids, D‐calycanthine (1) and L‐folicanthine (2),
were isolated from the active MeOH extract of the seeds of Chimonanthus praecox
Link. The structures of the two compounds were established by 1H‐ and 13C‐NMR,
and MS (FAB, ESI) analyses. In the in vitro tests, compounds 1 and 2 showed
significant inhibitory activities against five plant pathogenic fungi
