“…Sensitization may occur by direct skin contact with the plants, and from plant components present in cosmetics and topical medicines. In addition to allergic CD and airborne allergic CD, photoallergic CD and chronic actinic dermatitis may occur . The main allergens of the Compositae are sesquiterpene lactones (SLs), which are present in different compositions and concentrations in the plants.…”

Background The Compositae plant family includes many thousands of species, making it one of the most widespread group of plants worldwide. Sensitization to Compositae allergens may occur in private or in occupational settings. Objectives To monitor the current spectrum of sensitization to Compositae allergens, especially in cooks and florists. Methods We retrospectively analysed patch test results obtained with two Compositae mixes (CMs) (CM I and CM II; switch in October 2011), their individual components, and sesquiterpene lactone (SL) mix in 1492 cooks, 851 florists, and a control group (118 358 other patients) registered in the IVDK, 2007 to 2016. Results Florists reacted significantly more frequently to CM I and II (CM I, 8.7%; CM II, 10.6%) than did cooks (CM I, 2.1%; CM II, 0.8%) and controls (CM I, 1.3%; CM II, 1.2%). Additional testing with SL mix detected 14.3% more sensitizations than CM I or CM II alone. Conclusions Florists are at considerable risk of sensitization to Compositae allergens. Patch testing with both CM and SL mix is recommended.

“…Plants belonging to the Brassicaceae family are widely distributed in the nature because they include around 375 genera and 3200 species (LeCoz and Ducombs 2006). These plants have captured the attention of general public due to the importance of glucosinolates, which are abundant compounds in edible parts of the plants and have important biological activities.…”

Main conclusion Glucosinolates are biologically active compounds which are involved in plant defense reaction. The use of plant in vitro cultures and genetic engineering is a promising strategy for their sustainable production.Glucosinolates are a class of secondary metabolites found mainly in Brassicaceae, which contain nitrogen and sulfur in their structures. Glucosinolates are divided into three groups depending on the amino acid from which they are biosynthesized. Aliphatic glucosinolates are generally derived from leucine, valine, methionine, isoleucine and alanine while indole and aromatic glucosinolates are derived from tryptophan and phenylalanine or tyrosine, respectively. These compounds are hydrolyzed by the enzyme myrosinase when plants are stressed by biotic and abiotic factors, obtaining different degradation products. Glucosinolates and their hydrolysis products play an important role in plant defense responses against different types of stresses. In addition, these compounds have beneficial effect on human health because they are strong antioxidants and they have potent cardiovascular, antidiabetic, antimicrobial and antitumoral activities. Due to all the properties described above, the demand for glucosinolates and their hydrolysis products has enormously increased, and therefore, new strategies that allow the production of these compounds to be improved are needed. The use of plant in vitro cultures is emerging as a biotechnological strategy to obtain glucosinolates and their derivatives. This work is focused on the biosynthesis of glucosinolates and the bioactivity of these compounds in plants. In addition, a detailed study on the strategies used to increase the production of several glucosinolates, in particular those synthesized in Brassicaceae, using in vitro plant cultures has been made. Special attention has been paid for increasing the production of glucosinolates and their derivatives using metabolic engineering.

“…Positive reactions to L. nobilis , Compositae mix and sesquiterpene lactone mix suggest the diagnosis of sesquiterpene lactone‐induced allergic contact dermatitis. The role of sesquiterpene lactones in patients sensitized to laurel oil has been discussed in some studies . The sesquiterpene lactones are characterized by the presence of a γ‐butyrolactone ring with an exocyclic α‐methylene group.…”

“…Contact allergy is directed primarily against the α‐methylene group. Cross‐reactions among plants belonging to the Compositae family, plants of the genera Frullania (Jubulacea family) and Laurus (Lauracea family) and various members of the family Magnoliacea, such as Michelia lanuginosa , have been described in the literature . Patients allergic to laurel oil should therefore avoid products containing extracts, and contact with plants, known to contain sesquiterpene lactones.…”
