“…Diverse volatile compounds were observed in the different Piper species. In accordance with Varughese et al [22] and Srivastave et al, [23] the total profile of volatile compounds in the 10 Piper species revealed the predominance of esters, hydrocarbons, aldehydes, and alcohols. Volatile assemblages differed considerably among the different Piper species (BCS = 22.78% ± 1.98%, range: 3.15-58.83%, n = 45 comparisons, Table 2).…”

The volatile compounds of 10 Piper species cultivated in Hainan Island, China, have been investigated. Eighty compounds were profiled after headspace-solid phase microextraction (HS-SPME) with gas chromatographymass spectrometry (GC-MS). Mean Bray-Curtis similarity value was only 22.78 ± 1.98% among the different Piper species. The volatile compounds were largely grouped as hydrocarbons, aldehydes, alcohols, acids, ketones, esters, and phenols. The main compounds comprised benzaldehyde, cinnamaldehyde, β-caryophyllene, ocimene, lavandulol, myrcene, cubebene, terpinene, linalool, α-caryophyllene, β-elemene, and germacrene. Principal component analysis revealed that Piper laetispicum, Piper longum, Piper hainanense, Piper betle, and Piper flaviflorum were characterized by high contents of β-caryophyllene, α-caryophyllene, germacrene, and β-pinene. Piper puberulum and Piper cathayanum were associated with high contents of linalool, myrcene, and germacrene D. On the other hand, Piper pseudofuligineum and Piper retrofractum were related with high contents of ocimene. Finally, Piper auritum was associated with high content of cinnamaldehyde. Volatile profiling of Piper species by HS-SPME-GC-MS and the interrelationship investigated among the volatiles can be used as a roadmap for future resource utilization or biotechnological applications.

“…The phytochemistry of P. longum has been reviewed [2,39,40]. The leaf essential oil of P. longum from the Western Ghats region of Kerala, India, had elemol (22.5%), β-caryophyllene (16.8%), and α-humulene (5.8%) as the major components, while the stem essential oil was dominated by β-pinene (34.8%), α-pinene (14.0%), limonene (10.3%), and β-caryophyllene (9.3%) [41]. A report on the leaf essential oil of P. longum from Nghệ An Province, Vietnam showed the major components to be fonenol (40.5%) and elemol (8.2%) [42], and is, therefore, remarkably different from the P. longum essential oil in this present study, which was composed largely of α-pinene (5.1%), β-pinene (10.6%), β-caryophyllene (7.9%), ( E )-nerolidol (8.1%), and two unidentified sesquiterpenoids (5.7% and 11.9%).…”

Chemical Compositions and Mosquito Larvicidal Activities of Essential Oils from Piper Species Growing Wild in Central Vietnam

et al. 2019

Mosquitoes are the deadliest animals on earth and are the vectors of several neglected tropical diseases. Recently, essential oils have emerged as potential renewable, cost-effective, and environmentally benign alternatives to synthetic pesticides for control of mosquitoes. In this work, thirteen species of Piper were collected from different areas of central Vietnam. The essential oils were obtained by hydrodistillation and analyzed by gas chromatography–mass spectrometry. The essential oils were screened for mosquito larvicidal activity against Aedes aegypti. Four of the Piper essential oils showed outstanding larvicidal activity against Ae. aegypti, namely P. caninum, P. longum, P. montium, and P. mutabile, with LC50 and LC90 values less than 10 µg/mL. Multivariate analysis has correlated concentrations of β-caryophyllene, β-bisabolene, α-pinene, and β-pinene with mosquito larvicidal activity.

“…However, cinnamon essential oil used in the present work had more than 80% eugenol and less than 1% cinnamaldehyde in its composition. Some studies have reported that the extraction method (Fisher & Phillips, 2008), climatic and agronomic factors -such as fertilization, irrigation, and plant development phase at the time of extraction (Masotti et al, 2003) -, as well as the plant part used for extraction (roots, fruits, leaves, or stems) could affect the composition of essential oils (Varughese et al, 2016).…”

The objective of this work was to evaluate the effect of rosemary, cinnamon, citronella grass, and clove essential oils on the in vitro growth of Penicillium expansum, on the diameter of blue mold lesions, and on the physical and chemical attributes of 'Fuji' apples stored under refrigeration for different periods of time. The compositions of the essential oils were determined, and their effects on the growth inhibition, number, and viability of fungal spores in vitro were evaluated at 0, 100, and 1,000 μL L-1 oil concentrations. At postharvest, evaluations were performed for fruit treated with 0, 50, 100, and 500 μL L-1 essential oil and kept under refrigeration for 30 days, and for fruit treated with 0, 100, and 500 μL L-1 oil and kept under refrigeration for two days. The essential oils - eucalyptol (rosemary), eugenol (cinnamon), citronellal (citronella), and eugenol (clove) - reduce the growth, number, and viability of P. expansum spores 24 hours after the induction to germination, as well as the diameter of blue mold lesions in apples, except for citronella oil at 500 μL L-1 after 30 days of cold storage. There are no changes in the physicochemical attributes of apples, treated with different concentrations of the oils after refrigeration for five months, followed by seven days at room temperature.
