“…In this sense, we can also suggest that the greatest need of protection against environmental factors, mainly the high luminosity, could also be related to the highest density of capitate trichomes (longer) in the adaxial leaf surface of H. villosa. Hyptis species are mainly known by the production of essential oils with aromatic and medicinal potentials (Silva et al 2013). In fact, terpenes were histochemically detected in all the glandular morphotypes analyzed, and can represent the major chemical category of substances responsible for the aromatic properties of H. villosa.…”

“…Hyptis is one of the most common genera of Lamiaceae in the Brazilian flora (Silva et al 2013), comprising several species with medicinal value (Falcão & Menezes 2003). The bioactive potential of the essential oils of Hyptis species have been proved by their antibacterial (Souza et al 2003), antifungal (Oliveira et al 2004) and antitumoral (CostaLotufo 2004) properties.…”

Lamiaceae contains many species known for their aromatic properties that are produced by the production of essential oils in glandular trichomes. Hyptis is one of the most common genera of Lamiaceae in the Brazilian fl ora, and includes several species with medicinal value. However, studies on the morphology and functioning of their glandular trichomes are lacking. We analyzed the morphology, histochemistry and ultrastructure of the glandular trichomes in leaves of H. villosa, emphasizing the diff erential distribution of actin fi laments and microtubules in cells secreting hydrophilic and lipophilic compounds. Four morphotypes of glandular trichomes were identifi ed. Total lipid, terpenes, alkaloids, phenolic compounds, proteins and polysaccharides were histochemically detected in all morphotyes. Th is evidences the mixed nature of the secretions of this species, although there are diff erences in the prevalence of lipophilic and hydrophilic components among the glandular morphotypes and among the cells of the same trichome. Th e actin microfi laments are more abundant in cells that secrete mainly hydrophilic compounds, and microtubules predominate in cells that secrete lipophilic compounds. Our results corroborate the correlation between the glandular morphotype and the composition of the secretion produced, with a diff erential distribution of the cytoskeletal elements according to the prevalence of either hydrophilic or lipophilic substances.

“…It is considered a biodiversity hotspot, that is, presenting high concentrations of endemic species under strong anthropic pressure . Although over 12 000 plant species have been cataloged in this biome, studies regarding the identification of their volatile chemical compounds are still lacking . To the best of our knowledge, except for Eremanthus erythropappus DC.…”

During a bioprospection study in the Brazilian Cerrado, samples of Bidens graveolens Mart., an endemic species, were investigated. Chemical and olfactive analyses were performed on the essential oil obtained from fresh leaves of B. graveolens collected in November 2013 (BG1) and May 2014 (BG2). A total of 60 compounds were identified in the essential oil extracted from fresh leaves, by hydrodistillation. The main constituents were identified as monoterpene hydrocarbons, ranging from 86.5% to 89.6%. Limonene was the major compound, accounting for 22.8% in BG1 and 47.7% in BG2. Thirty‐three–oxygenated monoterpenes were identified, comprising about 9% in both essential oils (EO). The attributes described by the panelists are in accordance to the sensorial profile. Myrcene, limonene, epoxy‐myrcene, and limonene dioxide were rated by all panelists. Present at a frequency of 83.3%, α‐pinene, β‐pinene, α‐pinene oxide, and carvone were picked out by five panelists. It is noteworthy that most compounds rated with the highest intensity score belonged to the oxygenated monoterpene class, considered the most expressive terpene class used in perfumery. In general, these compounds were described as presenting green, herb, spicy, fresh, and camphoraceus odors.

A review of the phytochemical profiling and biological activities of Hyptis Jacq.: a Brazilian native genus of Lamiaceae

Hyptis Jacq. (Lamiaceae) has been used in traditional medicine for the treatment of many diseases around the world. However, Harley and Pastore in 2012 proposed a new circumscription for this large genus, reducing its number of species, but supporting its monophyly. Hyptis and Peltodon were used as keywords, and triage of articles was performed using genus delimitation sensu Harley and Pastore. Only 29 species have some type of record in the literature for their medicinal use and chemical description, corresponding to 20% of the 148 species. Most cited biological activities were the antioxidant activity, reported for 9% of the species, and the antifungal activity reported for 5% of the species. For 11% of the species was described the essential oil composition, while non-volatile compounds were reported for only 6% of them. Terpenes, flavonoids, and caffeic acid derivatives are the most reported compounds for this genus. Only 8% of the species are reported as medicinal, with potential as antibacterial and antiparasitic, pointing to relevance of Hyptis to bioprospecting studies, especially in South America and Africa. However, there is a lack of studies regarding isolated compounds concerning their toxicology and efficacy, important information to achieve the production and the effective use of Hyptis as a herbal medicine.
