“…The comparative study of the four plants showed strong similarities in some components in addition to the disappearance of some compounds. The differences in the major constituents of EOs from A. monosperma plants grown wild in Egypt and Saudi Arabia may be attributed to many factors, such as geographical origin, climate, soil composition, seasonal variation, and harvesting time…”

The chemical composition of essential oils (EOs) distilled from three wild Artemisia species, Artemisia herba‐alba, Artemisia judaica, and Artemisia monosperma, collected from Egypt, and Saudi Arabia, were analysed by gas chromatography–mass spectrometry (GC‐MS). The antibacterial activities of the EOs for all species were determined using the Agar disc diffusion method. The yield of the EOs ranged from 0.16 to 0.49%. The results showed that A. monosperma plants growing in Saudi Arabia gave the highest yield, compared with A. herba‐alba, A. judaica, and A. monosperma collected from Egypt. In total, 92 volatile compounds were identified from the aerial parts of the plants using GC‐MS. Oxygenated monoterpenes were the major class in A. herba‐alba (75.31%) and A. judaica (83.07%), whereas monoterpene hydrocarbons were the major representative group in A. monosperma collected from both Saudi Arabia (34.23%) and Egypt (36.23%). Yomogi alcohol (22.4%), artemesia alcohol (9.91%), and 1,8‐cineole (9.68%) were the major components of the EO of A. herba‐alba, whereas camphor (31.4%), piperitone (29.9%), and endo‐borneol (5.72%) were characterized as the main compounds in A. judaica. β‐Vinylnaphthalene (24.89%), β‐eudesmol (15.41%), and β‐pinene (20.67%) represented the main components of the EO of Saudi Arabian A. monosperma, but β‐pinene (11.89%), (–)‐spathulenol (8.84%), p‐cymene (8.83%), and shyobunone (7.05%) were the major components of the EO of Egyptian A. monosperma. Herein, a comparative analysis between the EOs of Egyptian Artemisia and those collected from Saudi Arabia was performed with principal components analysis (PCA) and agglomerative hierarchical clustering (AHC). The minimum inhibitory concentration (MIC) values ranged from 0.5 to2.5 μL per disc against different microorganisms. Artemisia judaica and A. monosperma (Saudi Arabia) plants had the highest MICs and A. monosperma (Egypt) had the lowest MIC, which may indicate different compositions as a result of climatic variation.

“…The berries of J. rigida have been widely used in Korean traditional medicine to treat rheumatoid arthritis and dropsy (Lee et al, 2010) and its branches and leaves utilized in traditional Mongolian medicine in China and as an important raw material to provide essential oil for the chemical industry (Wei and Shibamoto, 2007; Wu and Lin, 2014; Abdel et al, 2015). Chemical and pharmacological research on J. rigida has led to the discovery of bioactive components, such as flavonoids and phenolic compounds that potentially contribute to its antioxidant activity (Robards et al, 1999; Woo et al, 2011; Taviano et al, 2013).…”

Juniperus rigida (J. rigida) which is endemic to East Asia, has traditionally been used as an ethnomedicinal plant in China. This study was undertaken to evaluate the quality of J. rigida samples derived from 11 primary regions in China. Ten phenolic compounds were simultaneously quantified using reversed-phase high-performance liquid chromatography (RP-HPLC), and chlorogenic acid, catechin, podophyllotoxin, and amentoflavone were found to be the main compounds in J. rigida needles, with the highest contents detected for catechin and podophyllotoxin. J. rigida from Jilin (S9, S10) and Liaoning (S11) exhibited the highest contents of phenolic profiles (total phenolics, total flavonoids and 10 phenolic compounds) and the strongest antioxidant and antibacterial activities, followed by Shaanxi (S2, S3). A similarity analysis (SA) demonstrated substantial similarities in fingerprint chromatograms, from which 14 common peaks were selected. The similarity values varied from 0.85 to 0.98. Chemometrics techniques, including hierarchical cluster analysis (HCA), principal component analysis (PCA), and discriminant analysis (DA), were further applied to facilitate accurate classification and quantification of the J. rigida samples derived from the 11 regions. The results supported HPLC data showing that all J. rigida samples exhibit considerable variations in phenolic profiles, and the samples were further clustered into three major groups coincident with their geographical regions of origin. In addition, two discriminant functions with a 100% discrimination ratio were constructed to further distinguish and classify samples with unknown membership on the basis of eigenvalues to allow optimal discrimination among the groups. Our comprehensive findings on matching phenolic profiles and bioactivities along with data from fingerprint chromatograms with chemometrics provide an effective tool for screening and quality evaluation of J. rigida and related medicinal preparations.

“…These differences of chemical composition of the volatile oils may be attributed to a number of factors. Such factors may include differences in botanical origin, climatic conditions, geographical locations, and soil composition . In our work, six kinds of plants from Youyang County, Chongqing City, P. R. China, have analogous geographical origins and climate factors.…”

In this study, volatile oils of six Hawk tea varieties were studied for their chemical composition, antioxidant and antimicrobial activities to screen the most suitable botanical origins of Hawk tea. A total of 72 components were separated and identified from the six oils. The major constituents of the volatile oils were: α-pinene, camphene, limonene, 1,8-cineole, linalool, cis-nerolidol, and germacrene B. Moreover, the volatile oils were evaluated for antioxidant potential and antimicrobial activities. The results showed that all volatile oils exhibited acceptable antioxidant and antimicrobial activities, which suggested that these volatile oils may serve as natural alternatives to synthetic antioxidants and preservatives to be applied in food and pharmaceutical industries. Principal component analysis results denoted that some major compounds may be closely related to the antioxidant and antimicrobial activities. It also showed that the volatile oils from Litsea coreana var. lanuginosa and Litsea pungens Hemsl. were characterized by positive values of first two principal components, indicating higher active chemical compounds and antioxidant and antimicrobial activities compared with other species. Thus, they were temporarily considered as good sources of Hawk tea.
