“…Secondary calli contained about three times higher concentrations of thiophenes than tertiary calli. The occurrence of the major thiophenes (BBTOH, BBT, BBTOAc, α-T) in leaves and roots of T. patula (Breteler and Ketel 1993 ) corresponded with the data of Sütfeld ( 1982 ).…”

“…Existence of the sulphur-containing compounds in MeOH extract of Ferula assa-foetida leaves, are of pharmacological interest because they could have insecticidal effect and so contribute to the plant's overall defense mechanism (Breteler and Ketel 1993;Huang et al 2000;Nwachukwu et al 2012). Se dkon et al (1998) showing that essential oil, (E)-1-propenyl sec-butyl disul de is the major component (58.9%) in Iranian Ferula assafoetida.…”

“…The thiophene derivatives symbolize one of the most thoroughly examined groups of phototoxic phytochemicals (Downum 1992;Breteler and Ketel 1993). The sulfur containing compounds such as thiophenes detected from Tagetes owning high insecticidal (Perich et al 1995) The effect of phenolic compounds on larvae of the mosquito, Stegomyia aegypti (= Aedes aegypti), the vector of dengue, has been also reported (Marston et al 1993;Chowdhury 2008).…”

Studies were conducted to evaluate the toxicity of methanol (MeOH) extract from Ferula asafoetida Linn. (Umbelliferae) leaves on female adults and larvae of the lesser pumpkin fly, Dacus ciliatus (Diptera: Tephritidae). Direct-dip bioassays for larvae and topical bioassays for adults of fly were used to assess mortalities. Mortality increased significantly with rising concentrations. The intermediate lethal concentrations (LC50), calculated 7.3 mg/ml (7300 ppm) for larvae. The female adult LC50 was 409 µg/insect. The chemical composition of the isolated MeOH extract from Ferula asafoetida leaves was examined by gas chromatography-mass spectrometry. The major compounds were 2, 3, 4, 5-Tetramethyl thiophene (22.1%), Phenol, 3-pentadecyl- (21.2%) and Mono (2-ethylhexyl) phthalate (15.98%). The results suggested that the extract from the tested plant could be used as a potential control agent for this pest.

“…The already published studies demonstrate that the alcoholic extracts from Tagetes species (T.patula, T.minuta, T.erecta, T.tenuifolia, T.lucida), plant and/or root or volatile oil possess antifungal properties (Saha and Walia 2012); (Ibrahim, et The substances present in the Tagetes plants exert an allelopathic effect to the organisms' rhizosphere, thus the soil nematodes would be annihilated at thiophenes levels under 1 ppm. Research works showed that the biosynthesis of these compounds happens inside the roots, where the thiophene content has been monitored for in vitro generated cultures (Margl, Eisenreich, et al 2001); (Vijayta, Shanker and ur Rahman 2015); (Breteler and Ketel 1993). Though, the thiophenes have been identified and assayed in variable quantities in all plant organs.…”

The species of the genus Tagetes (family Asteraceae) known as ˝marigolds˝ are usually cultivated as ornamental plants, but are also studied and valued for their pharmacological properties in medicinal practice and for their biological actions in agriculture. The antifungal effect of the extracts, thanks to the content of thiophenes has been demonstrated in numerous studies. The study aims to obtain a qualitative extract from Tagetes patula L. (French marigold) with antifungal properties. The terthiophene in the extract obtained from dried inflorescences of a cultivar of Tagetes patula L. has been assayed by gas-chromatography, based on the calibration curve of the reference substance and has been compared to the content of the vegetal product. The extraction yield of the identified thiophenes, calculated as areas ratio between the extract and the plant, was 78%, while the median recovery ratio of the terthiophene (concentration in plant 0.021%) was 90%. The content corresponds to a significant potential of the antifungal effect of the extract.
