“…In addition, there is only one reference concerning the essential oil of a species (Sinningia aggregata) from the same family (Gesneriaceae). 28 However, the volatile profiles of S. aggregata (main contributors of the oil were methyl linoleate (28.4 %), 1-octadecanol (16.9 %), (Z)-nerolidyl acetate (8.8 %), spathulenol (7.8 %) and (E)-nerolidol (6.7 %)) and of the currently analyzed Ramonda species differed significantly. For example, sesquiterpenoids were not among the identified volatiles in either R. serbica or R. nathaliae, while these comprised ca.…”

GC and GC/MS analyses of the essential oils hydrodistilled separately from fresh leaves and roots of Ramonda serbica and Ramonda nathaliae, together with diethyl ether extracts of their roots, enabled the identification of 82 constituents accounting for between 88.9 and 94.5 % of the oils and extracted compounds. Although phenylacetaldehyde was one of the major contributors (20.5-57.1 %) of all the oils, it was only a minor contributor to the extracts. The latter were characterized by a large amount of squalene (R. serbica --36.0 %; R. nathaliae -59.4%) and steroids (R. serbica -27.4 %; R. nathaliae --14.1 %). Squalene was also the most abundant compound in R. nathaliae root oil (29.0 %), but was not detected in the corresponding R. serbica oil. While the root oils and extracts of both species contained comparable amounts of volatile fatty acids, there were significant differences in their contents in the oils hydrodistilled from the leaves of R. serbica and R. nathaliae (18.7 % and 0.6 %, respectively). The presented results provide the first insight into the unique sets of volatiles produced by these distinctive, closely related, relict taxa, which disclose their specific adaptive advantages.

“…The dominant compounds in the aerial parts of S. aggregata were longchain aliphatic compounds and oxygenated sesquiterpenes while that of R. serbica and R. nathaliae leaf oils were reported to be phenylacetaldehyde. The concentration of sesquiterpenes noted in the essential oils of D. tomentosa is significantly higher (78.7%) when compared to that of S. aggregata (40.2% [7,8].…”

The essential oil from the leaves of Didymocarpus tomentosa was extracted by hydrodistillation and analyzed by GC/FID and GC/MS. Twenty five constituents amounting to 81.6% of the oil were identified. The leaf oil contained 78.7% sesquiterpenes and 2.9% monoterpenes. The leaf essential oil of D. tomentosa is a unique caryophyllene-rich natural source containing β-caryophyllene, caryophyllene oxide, α-humulene and humulene oxide. The cytotoxic activity of the oil was determined by the BSLT using shrimp larva and the MTT assay using HeLa tumor cell line. The oil showed significant cytotoxic activity with LC 50 and IC 50 values of 12.26 and 11.4 µg/mL, respectively. This is the first report on the chemical composition and cytotoxic activity of the essential oil of D. tomentosa.

Já Stefanello et al (2005) avaliaram a espécie Sinningia aggregata onde obtiveram aroma intenso, esse aroma advém do óleo essencial das flores produzidas quase que exclusivamente por tricomas glandulares.…”

“…Conforme Perret et al (2001) a tribo Sinningieae onde algumas espécies produzem óleos essenciais.Esta característica é importante para perpetuação da espécie no ambiente, visto que, a maioria das espécies de Sinningia é polinizada por beija-flores ou abelhas do gênero apis, sendo o fator determinante a morfologia floral. Os óleos essenciais não são comuns para o gênero Sinningia, onde foram identificados apenas nas espécies de Sinningia aggregata, Sinningia harleyi e Sinningia valsuganensis (Chautems, 1991, Stefanello et al 2005.…”

A presença de Sinningia elatior (Kunth) Chautems (Gesneriaceae) é citada pela primeira vez na flora da região Centro-Oeste em Goiás, Brasil. Foram realizadas coletas de plantas inteiras de S. elatior em área de mata de galeria. O material foi levado para o laboratório onde foi separado por órgão vegetativo (rizoma, galho, folha e flor). Foram realizadas análises de diafanização foliar, morfometria dos órgãos vegetais, o pólen foi avaliado por modelagem matemática em 3D e para os extratos, análises físico-química, fitoquímica e hemolítica. As plantas de S. elatior apresentaram em todos os órgãos superiores a presença tricomas tectores, com inervação até 5ª ordem, os estômatos são do tipo anisocíticos, para a fitoquímica, todas as classes de compostos foram positivas, exceto para resinas. Os extratos etanólicos de S. elatior demonstraram importante ação hemolítica no tempo máximo de 5 minutos. Os resultados obtidos neste estudo para S. elatior apresentaram importantes dados morfológicos, morfométricos para os órgãos aéreo e subterrâneo, e importantes classes de compostos fitoquímicos com importância nas indústrias agrícola, farmacêutica e alimentícia.
