“…The essential oils from shade-dried plant parts flower-40g, leaf-48g and stem-57g of G. gelida were isolated by hydrodistillation in a British-type Clevenger apparatus using an ice bath 15 for cooling system 4 h yields: 0.06, 0.04 and 0.03 v/w , respectively . The volatile oils were taken by dissolving in HPLC grade hexane 1 mL , dried over anhydrous Na 2 SO 4 , and, after filtration, kept in the dark at 4 in sealed brown vials until tested 14,15 .…”

“…Despite this great diversity, only about one hundred and sixty papers devoted to the study of the essential oils and volatile compounds of Senecio species (which was the former genus of P. herzogii ) are reported in the SciFinder ® database [ 13 ]. Less than ten of them show the presence of low percentages (<2%) of thymol methyl ether and only three the occurrence of carvacrol methyl ether ( Table 2 ) [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. Surprisingly, one paper mentions the ambiguous o -methyl thymol as an identified compound in the S. scandens essential oil [ 19 ].…”

Over 15 years, with the support of a Canadian funding agency, the Universidad Mayor de San Simón, in Bolivia, undertook a large survey of aromatic plants of the South American country. More than a hundred species were studied under various aspects, including the production and characterization of essential oils. As part of this survey, the chemical composition of an essential oil sample obtained from Pentacalia herzogii (Asteraceae) growing wild in the High Valley region of the department of Cochabamba was determined by a combination of GC and GC-MS measurements. α-Pinene was the main constituent of this essential oil (34%), accompanied by limonene (22%) and germacrene D (7.5%) as well as an important fraction of methoxylated monoterpenoids. They were mainly isomers of thymol methyl ether, accounting for 13% of the chromatogram. A new quantitatively important compound (9%) was identified through NMR and chemical synthesis as 4-isopropyl-6-methylbenzo[d][1,3]dioxole, and designated herzogole, alongside the minor related compound 1-isopropyl-2,3-dimethoxy-5-methylbenzene. The monoterpene benzodioxole featured a distinctive green-phenolic aroma which could raise interest for fragrance use. Since these compounds were not known naturally, a biosynthetic mechanism of their formation was proposed and put in perspective to illustrate the metabolic originality of P. herzogii.

P edicularis L. is a large hemi parasitic genus and, 12 taxa of Pedicularis are existing in Turkey [1]. Traditionally, Pedicularis was placed in Scrophulariaceae but, this genus has been transferred to Orobanchaceae based on molecular evidence [2,3]. Iridois and phenylpropanoid glycosides were isolated from P. condensata Bieb. [4]. Lignans glycosides, flavonoids and alkaloids were also obtained from some members of the Pedicularis as well as Iridois and phenylpropanoid glycosides [5]. Some species of the Pedicularis are used as traditional medicine by Chinese people [5]. Li et al. (2014) also determined that extracts of some species of Pedicularis from China have antitumor, hepatoprotective, anti-oxidative, antibacterial activity, antihaemolysis, fatigue relief of skeletal muscle and nootropic effects. The genus Pedicularis comprising about 500 medicinal herbs and mostly endemic to China, is one of those genera of this family [6]. Several species of this genus,
