“…Our results indicated that the six Lamiaceae essential oils have diverse chemical compositions, and they could serve as good sources of eugenol, patchouli alcohol, linalool, eucalyptol, β-caryophyllene, terpenyl acetate, chavibetol, camphor, γ-terpineol, borneol, and α-pinene. Some of these essential oils have been reported to demonstrate promising antioxidant, anti-nociceptive, anti-cardiotoxicity, anti-cancer, and anti-inflammatory activities (Sharma et al, 1994 ; Santos and Rao, 2000 ; Khan et al, 2014 ; Vyry Wouatsa et al, 2014 ; Fidyt et al, 2016 ; Mamadalieva et al, 2017 ; Nieto, 2017 ; Lian et al, 2018 ; Liu et al, 2018 ; de Souza et al, 2019 ; Luo et al, 2019 ; Oner et al, 2019 ).…”

Essential oils have attracted wide attention in recent years due to their extensive applications in natural functional ingredients, pharmaceutical preparations, biomedical products, and the cosmetics industry. In this study, the chemical compositions and biological activities of essential oils extracted from six Lamiaceae herbs, including Pogostemon cablin (Blanco) Benth. (PCEO), Perilla frutescens (L.) Britton (PFEO), Salvia japonica Thunb. (SJEO), Rosmarinus officinalis L. (ROEO), Lavandula angustifolia Mill. (LAEO), and Agastache rugosa (Fisch. & C. A. Mey.) Kuntze (AREO), were determined and analyzed. A total of 167 components were identified from the six essential oils by GC-MS analysis, with 35, 24, 47, 46, 54, and 37 components in PCEO, PFEO, SJEO, ROEO, LAEO, and AREO, respectively. Hierarchical cluster analysis of chemical compositions showed that the composition of the six essential oils was significantly different in content, and they were clearly divided into six classes. However, all of these six essential oils exhibited promising anti-inflammatory activity by inhibiting the expression of interleukin-1, interleukin-6, tumor necrosis factor-α, and cyclooxygenase-2 in rats with adjuvant arthritis, among which PFEO had the best performance. In addition, the six essential oils displayed significant cytotoxicity on B16 (IC50 = 86.91–228.91 μg/mL) and LNCaP cell lines (IC50 = 116.4–189.63 μg/mL). Meanwhile, all of them presented satisfactory antioxidant activity (IC50 = 4.88–13.89 μg/mL) compared with Trolox C (IC50 = 13.83 μg/mL), and SJEO (IC50 = 7.93 μg/mL) served as an optimal candidate natural antioxidant by DPPH assay. Taken together, these results indicate that the six Lamiaceae essential oils manifest excellent and diverse biological activities, enabling them to be used as perfect natural functional ingredients in antioxidant, antitumor, or anti-arthritic drugs. This study provides more references for pharmaphylogeny research and drug discovery from folk medicinal plants.

“…Essential oil constituents like thymol, eugenol, carvacrol, linalool, 1,8-cineole, geranial/neral, citronellal, isomenthone, and menthone are potent antioxidants. They can convert free radicals into more stable compounds by the addition of hydrogen atoms [63]. Strong antioxidant activity of essential oils is attributed to their phenolic structure [64].…”

Essential Oils - Advances in Extractions and Biological Applications

View full text Add to dashboard Cite

Essential oils are formed by a complex matrix of substances that are biosynthesized in the secondary metabolism of plants. Nowadays, different ecofriendly extraction techniques (e.g., ultrasound-, microwave-, enzyme-assisted extraction, and supercritical fluid by CO2, etc.) have been adopted to obtain essential oils. These techniques provide unique quality of essentials oils or extracts from aromatic plants in a short time with high energy savings. Essential oils not only impart aroma, but also possess antimicrobial and antioxidant activities. Health limitations in the use of synthetic additives have drawn researchers’ attention towards essential oils as safe natural preservatives. Therefore, this chapter summarizes novel technologies to recover essential oils or extracts. In addition, it focuses on application of essential oils and their constituents as green preservatives to retard microbial growth and oxidative spoilage.

“…A fração volátil de frutos e flores foi extraída por dois métodos distintos: hidrodestilação e extração em fase sólida. A extração por hidrodestilação [17] foi realizada com o auxílio de um aparelho de Clevenger que permitiu o isolamento dos óleos essenciais (OE) dos FV, FM e FF. Os FV e FM foram macerados com as cascas e sementes antes do processo de extração.…”

“…Inicialmente, para a avaliação da fração não volátil, foram produzidos extratos aquosos de acordo com o trabalho prévio de Souza et al (2019) [17], com pequenas modificações: cerca de 2,0 g de FV, FM (ambos após maceração com cascas e sementes) ou FF foram extraídos com água em ebulição (50 mL) por 5 minutos com agitação manual. Depois dessa etapa, cada extrato foi rapidamente resfriado sob água corrente, filtrado e seu volume foi ajustado para 100 mL com água destilada à temperatura ambiente.…”

“…O β-farneseno é descrito como um composto de odor herbáceo, cítrico, amadeirado e floral, apresentando um limiar de odor em água de 87 μg L -1 . Por último, o α-terpineol, com seu limiar de odor em água (330-353 μg L -1 ) um pouco mais elevado do que os demais, tem seu aroma associado a notas de fruta e folhas [17,31]. O triterpeno esqualeno foi o único composto terpênico encontrado em todas as amostras, independente da técnica de isolamento aplicada.…”

Dentre a diversidade de espécies de plantas alimentícias não convencionais (PANC), a Pereskia aculeata Miller, conhecida popularmente como ora-pro-nóbis (OPN), está sendo consumida cada vez mais no Brasil. O objetivo deste estudo foi avaliar a capacidade antioxidante e a composição das frações volátil e não volátil das flores e frutos de OPN. A fração volátil foi isolada por hidrodestilação e por extração em fase sólida e caracterizada por CG/EM e CG/DIC. Extratos aquosos obtidos das amostras foram avaliados quanto ao teor total de compostos fenólicos (Folin-Ciocalteu) e à atividade antioxidante (DPPH, FRAP e ORAC). A identificação dos ácidos fenólicos, flavonoides e alcaloides presentes nessas matrizes foi conduzida por CLAE/EMAR. Foram identificados um total de vinte e oito compostos voláteis nas amostras. O ácido hexadecanóico e o escaleno foram os únicos compostos detectados em todas as frações voláteis. O ácido hexadecanóico, linoleico, oleico e o fitol se destacaram quantitativamente. O β-linalol, α-terpineol, β-farneseno e trans-nerolidol têm potencial para influenciar o aroma da FF. No que diz respeito à fração não volátil, foram identificados 17 compostos (fenólicos e alcaloides) no FV e 11 na FF. A FF, entretanto, apresentou maior potencial antioxidante do que os frutos, o que pode ser explicado pela concentração desses compostos durante o processo de secagem dessas flores. Até onde sabemos, este é o primeiro estudo sobre o perfil fitoquímico e a atividade antioxidante das flores da Pereskia aculeata Miller, além de apresentar dados inéditos sobre o perfil de voláteis dos frutos desta espécie.
