“…Based on steam distillation, Cassel and Vargas [17] optimized the yield of citronella essential oil extraction. Previous study revealed that microwave assisted hydrodistillation was more efficient in terms of extraction time and energy consumption [18]. There have been many studies attempting oil extraction by hydrodistillation to solve the problem of separation efficiency, composition and utility of essential oils [19].…”

Composition of rosemary essential oil largely depends on the geographical position of the cultivated plant and conditions of the extraction process. In this study, fresh rosemary leaves were used for extraction of essential oil by hydrodistillation and evaluation of chemical compositions and physico-chemical characteristics of the obtained oil were performed. The yield of essential oil was 1.0 %. The physico-chemical parameters showed specific gravity (0.8978 g/cm3), acid index (1.122 mg KOH/g), ester index (15.708 mg KOH/g) and refractive index (1.464). Twenty three components were identified in Rosmarinus officinalis L. oil. The major components were α-pinene (35.54 %), eucalyptol (20.902 %), camphene (4.384 %), bicyclo[3.1.1]hept-3-en-2-one (7.794 %), caryophyllene (1.225 %), endo-borneol (4.147 %) and bornyl acetate (4.065 %). Present study unveiled differences in the chemical composition of Vietnamese rosemary oil comparing with similar studies carried out in other countries.

“…In spite of this, the two studies verified the expressive presence of the compound cation of caryophyllene. While in this work the caryophyllene oxide showed the major compound, with its higher concentrations at 55 ° C, in the experiments of Jesus et al (2016) this was the compound with the second highest concentration and remained more stable when stored in a freezer at a temperature of -20 ° C. In this way, we can see the instability of the chemical components in the essential oil when submitted to different temperatures.…”

“…Arrigoni-Blank et al (2010) reported that the differences between the chemical compositions can be justified because each genotype responds differently to the given environmental conditions and also to the drying process, which eliminates water from the material and increases the percentage of active principles in comparison with the fresh plant. Jesus et al (2016) also performed the drying of Hyptis pectinata samples, but at a single temperature of 40 ° C for four days, without variations in air drying drier rate. The oil was extracted by steam distillation and stored the samples of oils obtained at temperatures of ±32 ° C and -20 ° C. The objective of the work of Jesus et al (2016) was to evaluate the influence of the time and storage temperature of the oils obtained, and therefore performed chromatographic analyzes in 11 time periods over 360 days, diverging from this work, which aimed to verify the influence of the drying procedures on the chemical composition of Hyptis pectinata essential oil.…”

The present study assessed the effects of drying at different temperatures (35, 45 and 55 °C) and air velocities (1 and 2 m s -1 ) on the content and chemical characteristics of Hyptis pectinata essential oil. Drying was conducted in a fixed-bed dryer, and the temperatures and air velocities were controlled and recorded by an automated system. A 350±0.12 g quantity of fresh leaves was used for each of the four repetitions in each dryer. From the material obtained after drying, 60 g of each repetition was used to extract essential oil by the hydrodistillation method. Dichloromethane was used as the solvent, and anhydrous sodium sulfate was used as the desiccating agent. Gas chromatography in the forms of GC-MS and GC-FID were used for the chemical characterization of the essential oil compounds. Decreasing drying times and decreasing concentrations of essential oils were observed with increasing temperatures. A GC-MS analysis of the essential oil from H. pectinata leaves led to the identification of 19 compounds. A sesquiterpene called caryophyllene oxide was the most abundant compound under all drying conditions, with the highest concentration at a temperature of 55 °C, ranging from approximately 42 to 53%.

“…Six studies reported the composition of the essential oils from Mesosphaerum pectinatum (syn. Hyptis pectinata ) ( Tchoumbougnang et al, 2005 ; Arrigoni-Blank et al, 2008 ; Nascimento et al, 2008 ; Jesus et al, 2016 ; Feitosa-Alcantara et al, 2017 ; Oliveira de Souza et al, 2017 ). These oils presented as the major compounds the sesquiterpene hydrocarbons, β -caryophyllene ( 262 ), germacrene-D ( 269 ) and β -elemene ( 263 ).…”

Ethnopharmacological relevance The subtribe Hyptidinae contains approximately 400 accepted species distributed in 19 genera ( Hyptis , Eriope , Condea , Cantinoa , Mesosphaerum , Cyanocephalus , Hypenia , Hyptidendron , Oocephalus , Medusantha , Gymneia , Marsypianthes , Leptohyptis , Martianthus , Asterohyptis , Eplingiella , Physominthe , Eriopidion and Rhaphiodon ). This is the Lamiaceae clade with the largest number of species in Brazil and high rates of endemism. Some species have been used in different parts of the world mainly as insecticides/pest repellents, wound healing and pain-relief agents, as well as for the treatment of respiratory and gastrointestinal disorders. Aim of the review This review aims to discuss the current status concerning the taxonomy, ethnobotanical uses, phytochemistry and biological properties of species which compose the subtribe Hyptidinae. Materials and methods The available information was collected from scientific databases (ScienceDirect, Pubmed, Web of Science, Scopus, Google Scholar, ChemSpider, SciFinder ACS Publications, Wiley Online Library), as well as other literature sources (e.g. books, theses). Results The phytochemical investigations of plants of this subtribe have led to the identification of almost 300 chemical constituents of different classes such as diterpenes, triterpenes, lignans, α -pyrones, flavonoids, phenolic acids and monoterpenes and sesquiterpenes, as components of essential oils. Extracts, essential oils and isolated compounds showed a series of biological activities such as insecticide/repellent, antimicrobial and antinociceptive, justifying some of the popular uses of the plants. In addition, a very relevant fact is that several species produce podophyllotoxin and related lignans. Conclusion Several species of Hyptidinae are used in folk medicine for treating many diseases but only a small fraction of the species has been explored and most of the traditional uses have not been validated by current investigations. In addition, the species of the subtribe appear to be very promising as alternative sources of podophyllotoxin-like lignans which are the lead compounds for the semi-synthesis of teniposide and etoposide, important antineoplastic agents. Thus, there is a wide-open door for future studies, both to support the popular uses of the plants and to find new biologically active compoun...
