“…A chemotype also frequently found (type C; six individuals) presented a 33% camphor average concentration (see also results by 19,[21][22][23]36), together with terpenes characteristic of other chemotypes. High camphor concentrations were generally followed by high amounts of the oxygenated monoterpene 1,8cineole, e.g., sample nos.…”

Between 2001 and 2002, plant collections from wild populations of Norwegian tansy (Tanacetum vulgare L.) were studied with a focus on essential oil (EO) yield and composition in order to characterize the chemotypical EO variability. Tansy collections of 40 different locations from North, Mid-, and South Norway were transplanted to the Apelsvoll Research Centre Div. Kise in 2000 and grown for 2 years before the aerial parts (leaves and flower buds) were harvested in June 2002. The EO from individual plants was isolated from dried plant material by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS) on a DB5 column at the Plant Biocenter. The EO yield ranged between 0.35 and 1.90% (v/w) (average: 0.81%); the most abundant thujone plants were especially rich in EO volatiles (0.95%). On the basis of GC-MS data, seven chemotypes could be identified as follows: A, alpha-thujone (two individuals); B, beta-thujone (22); C, camphor (six); D, chrysanthenyl acetate/chrysanthenol (three); E, chrysanthenone (two); F, artemisia ketone/artemisia alcohol (three); and G, 1,8-cineole (two). The thujone chemotype was dominated by beta-thujone (81%) associated with alpha-thujone, but tansy plants rich in alpha-thujone were also detected (61%). The chemotypical classification of Norwegian tansy genotypes was underscored by preliminary studies from 2001, indicating the genetic uniformity and biochemical stability of the domesticated plants.

“…The composition of EO obtained from the five tansy genotypes in 2000 showed chemotypical variation (see Figures 2-4). All types contained β-thujone as one of the major compounds, with highest average amounts detected in Steinvikholmen, Brumunddal, and Goldsticks (3)(4)(5)(6), being also characterized by distinct levels of camphor. Plants from Alvdal and Brumunddal had more complex oil matrices (Table 6), and several monoterpenes (R-pinene, camphene) and oxygenated structures [1,8-cineole, bornyl acetate, borneol, and (E)-verbenol] could be detected in appreciable amounts.…”

Tansy (Tanacetum vulgare L.) was cultivated at the Norwegian Crop Research Institute at the Apelsvoll Research Centre, Division Kise, in the period from 2000 to 2001. The study focused on different harvesting regimens for high biomass production and essential oil (EO) yield and quality. Two tansy genotypes from Canada (Richters and Goldsticks) and three Norwegian genotypes (Steinvikholmen, Alvdal, and Brumunddal) were studied. The Canadian genotypes reached a height of 130-145 cm and showed a higher dry weight of aerial plant parts compared to the Norwegian plants in 2000. Similar oil yields could be observed for the Canadian types and genotype Steinvikholmen in the range of 30.8-34.6 L/ha when the plants were harvested twice during budding and before flowering after regrowth (year 2001). In contrast, single harvesting at the full bloom stage resulted in higher oil yields, between 42.1 and 44.5 L/ha (Canadian genotypes), whereas 21.0-38.4 L/ha was obtained from the Norwegian types. Tansy genotypes could be grouped into the following chemotypes: the mixed chemotypes Steinvikholmen (thujone-camphor), Alvdal (thujone-camphor-borneol), Goldsticks (thujone-camphor-chrysanthenyl type), and Brumunddal (thujone-camphor-1,8-cineole-bornyl acetate/borneol-alpha-terpineol) and the distinct chemotype Richters, with average concentrations of (E)-chrysanthenyl acetate >40% in both leaf and flower EO.

“…Echegaray & Rubluo, 1995: Buckley er nl., 1995. The lack of Gram-positive endophytic bacteria in tansy may be due to its volatile oils (camphor, sabinene, thujone and umbellulone) that according to other studies show bactericidal effect on Gram-positive bacteria but are less effective against Gram-negative bacteria (Holopainen & Kauppinen, 1989). Enterobacteriaceae such as E. agglomerans, and fluorescent pseudomonads such as P. jluorescens and P. marginalis (synonymous to P. jluorescens biovar 2) are considered to be plant-associated because they have been isolated from many field-grown andor micropropagated plants, e.g.…”

Alterations in growth of tissue‐cultured tansy (Tanacetum vulgare L.) treated with antibiotics

Effects of three antibiotics (cefotaxime, rifampicin and gentamicin) were tested on in vitro shoots cultures of tansy (Tunacetum vulgare L.). These antibiotics were selected because endophytic bacteria isolated from the in vitro shoot cultures of tansy showed that all bacteria were Gram-negative and their growth was reduced by these three antibiotics. Five isolates were Enterobacteriaceae, three were fluorescent Pseudomonas, and two were aerobic bacteria. Increased concentrations of antibiotics caused usually linear or quadratic changes on the initiation of shoot growth, shoot number, growth rate, and shoot height. These changes and changes in pH of the culture media were tansy genotype-dependent following treatments with gentamicin. Also, the treatment with rifampicin or cefotaxime showed a genotype-dependent effect, because they resulted in significantly higher percentage of rooted plants in one of the three tansy genotypes tested. The growth rate and length of shoots were reduced in the media containing both gentamicin and rifampicin, but less so than in media containing both gentamicin and cefotaxime.
