GC‐MS analysis of the essential oils of four tagetes species and the anti‐microbial activity of Tagetes minuta
Abstract
The chemical composition of essential oils from the flowering plants of four Tagetes species was examined by GC‐MS. Of the species examined only T. minuta L. was rich in β‐ocimene. The other major constituents of this species and of T. tenuifolia Cav. were dihydrotagetone, tagetone, and (E)‐ocimenone. These two species only contained small amounts of (Z)‐ocimenone but, in contrast, the essential oil of T. patula L. contained equal amounts of (Z)‐and (E)‐ocimenone. The oil from T. patula also contained limonene and β‐caryophyllene. The essential oil from T. erecta L. differed largely from the other three species containing mainly limonene, β‐caryophyllene, and piperitone. In agar‐diffusion experiments the essential oil of T. minuta inhibited the multiplication of fungi, Gram‐positive and Gram‐negative micro organisms.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
