Heracleum sphondylium L. subsp. sphondylium (Apiaceae) of the Isle of Skye (Scotland): the chemical composition of essential oil from the flowering aerial parts. Nat Prod Res 2024; 38:2920-2925. [PMID: 37533365 DOI: 10.1080/14786419.2023.2241147] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 06/29/2023] [Accepted: 07/17/2023] [Indexed: 08/04/2023]
Abstract
Heracleum is a large genus of plants belonging to Apiaceae family that includes about 90 species of biennial or perennial herbs. Several species of this genus are extensively used in various traditional medicines and, despite their content in toxic furanocoumarins, also as food. In the present study the chemical composition of the essential oil (EO) from flowering aerial parts of Heracleum sphondylium L. subsp. sphondylium, a plant distributed in Europe and North-West Africa, collected in the Isle of Skye (Scotland), was analyzed by GC and GC-MS. No one report has been previously published on any British accession. The result showed the presence of large quantity of sesquiterpene hydrocarbons and aliphatic esters, with bicyclogermacrene (31.6%) and octyl acetate (29.5%), by far, as the most abundant components. Considerations with respect all the other EOs of H. sphondylium taxa, studied so far, were carried out.

Abstract
INTRODUCTION Isolation and characterization of bioactive components from complex matrices of marine or terrestrial biological origins are the most challenging issues for natural product chemists. Biochemometric is a new potential scope in natural product analytical science, and it is a methodology to find the compound's correlation to their bioactivity with the help of hyphenated chromatographic techniques and chemometric tools. OBJECTIVES The present review aims to evaluate the application of chemometric tools coupled to chromatographic techniques for drug discovery from natural resources. METHODS The searching keywords "biochemometric," "chemometric," "chromatography," "natural products bioassay," and "bioassay" were selected to search the published articles between 2010-2023 using different search engines including "Pubmed", "Web of Science," "ScienceDirect," and "Google scholar." RESULTS An initial stage in natural product analysis is applying the chromatographic hyphenated techniques in conjunction with biochemometric approaches. Among the applied chromatographic techniques, liquid chromatography (LC) techniques, have taken up more than half (53%) and also, mass spectroscopy (MS)-based chromatographic techniques such as LC-MS are the most widely used techniques applied in combination with chemometric methods for natural products bioassay. Considering the complexity of dataset achieved from chromatographic hyphenated techniques, chemometric tools have been increasingly employed for phytochemical studies in the context of determining botanicals geographical origin, quality control, and detection of bioactive compounds. CONCLUSION Biochemometric application is expected to be further improved with advancing in data acquisition methods, new efficient preprocessing, model validation and variable selection methods which would guarantee that the applied model to have good prediction ability in compound relation to its bioactivity.

Abstract
Generally, thin-layer chromatography always undertakes the indispensable role in rapid screening and identification of specific compounds. Stationary phase is the core part of thin-layer chromatography with fixed property, which leading to the limitations of separation mode of only regulating the composition of mobile phase. This work was an attempt to fabricate the unique photosensitive thin-layer chromatography to make up the above major drawback. 4-[3-(Triethoxysilyl)propoxy]azobenzene (azo-PTES) was synthesized as photosensitive modifier to fabricate the photosensitive stationary phase, and the transformation of cis-trans structure of azo-PTES proceeds along with polarity difference under 365 nm and 473 nm irradiation. Based on this, the proposed photosensitive thin-layer chromatography shows the reversible switch of polarity of stationary phase by photoinduction, followed by the deserved reversible separation behavior. Furthermore, multi-regulation in spatial dimension was achieved based on the high freedom of spatial regulation of photoinduction, which brings about the integration of stationary phase with different polarity, just by photoinduction. The concept of photosensitive thin-layer chromatography provides new idea for improving separation efficiency and developing multi-dimensional thin-layer chromatography on the one plate.

Abstract
This study reports the synthesis of the room temperature ionic liquid 1-propyloxy-3-ethoxyimidazolium bis(trifluoromethane)sulfonamide for the extraction of bergapten and bergamottin from hydroalcoholic cosmetic samples by means of dispersive liquid-liquid microextraction. Molecular structures of the final ionic liquid as well as intermediate products were confirmed by nuclear magnetic resonance spectroscopy. Analyses were performed with high performance liquid chromatography with subsequent diode array and fluorescence detection. The extraction procedure was optimized with the design of the experiment using a three level Box-Behnken approach. Applying the synthesized room temperature ionic liquid as extraction medium, the optimized workflow demonstrated high recoveries illustrating powerful isolation properties for furanocoumarins, which are comparable or even better than using typical extraction solvents. Moreover, the workflow was validated regarding instrumental limits, linearity, accuracy, repeatability and stability of analytes according to international guidelines. To test its applicability on a more complex matrix, hydroalcoholic cosmetic samples were analyzed. Despite highly complex matrices, accurate and precise quantification in the range of 0.04-1.25 μg mL-1 was achieved in spiked and unspiked samples, with bias <10% and RSD < 12%.

Abstract
Hexane extracts of Heracleum verticillatum, H. sibiricum, H. angustisectum, and H. ternatum were studied for their furanocoumarin content antioxidant potential and acetylcholinesterase and α-amylase inhibitory activities. Quantification of the furanocoumarins was performed by 1 H-NMR. Pimpinellin was found to be the main component in the roots of all studied species. Bergapten and imperatorin were the major compounds in the fruits of H. sibiricum and H. verticillatum, respectively, while byakangelicol dominated in H. angustisectum and H. ternatum fruits. The leaf and fruit extracts of H. angustisectum demonstrated the highest DPPH radical scavenging activity and TEAC (IC50 0.58 mg/mL and 1.83 mm, respectively). The root extracts of H. verticillatum and H. angustisectum were found to be the most effective against acetylcholinesterase (IC50 0.30 and 0.34 mg/mL, respectively). The studied extracts were not active or demonstrated a weak inhibitory effect (%Inh. up to 29.7) towards α-amylase.

Abstract
The composition of the essential oils and the furanocoumarin profiles of CH2 Cl2 extracts from underground parts and fruits of nine Heracleum taxa (Apiaceae) from Southeastern Europe were statistically analyzed to evaluate their chemosystematic significance. Eight investigated taxa (H. orphanidis and members of H. sphondylium group: H. sphondylium, H. sibiricum, H. montanum, H. ternatum, H. pyrenaicum subsp. pollinianum, H. pyrenaicum subsp. orsinii and H. verticillatum) belong to the type section of the genus. Additionally analyzed taxon, H. austriacum subsp. siifolium, belongs to H. sect. Wendia. Qualitative and quantitative analysis of the essential oils was performed by GC-FID and GC/MS, and of the furanocoumarins by LC/MS. Furanocoumarins were identified using standards and/or based on UV, MS, 1 H- and ROESY NMR spectra. Multivariate statistics (PCA, nMDS, UPGMA) of analyzed metabolites showed that the investigated taxa were grouped according to their taxonomic classification. PCA revealed the significance of some monoterpenes and (Z)-falcarinol of the underground parts oils, octyl esters of the fruit oils, and most of the total of 12 identified furanocoumarins.

Abstract
Although some widespread, native cow parsnips (Heracleum L. spp., Apiaceae) had broad medicinal and culinary applications throughout history, the knowledge about their volatile constituents is insufficient. This work investigates the composition and bioactivities of H. sphondylium L. (HSPH), H. sibiricum L. (HSIB) and H. montanum Schleich. ex Gaudin (HMON) essential oils. The composition was tested by GC and GC-MS. (Z)-β-Ocimene was the most abundant in HSPH (28.9%) and HMON (20.4%) root oils, while in HSIB root oil, β-pinene (26.2%), methyl eugenol (22.3%) and elemicin (25.6%) prevailed. Leaf and flower oils were dominated by various sesquiterpenes (germacrene D, β-sesquiphellandrene, (E)-β-farnesene and/or (E)-caryophyllene) and/or phenylpropanoids (apiole, methyl eugenol, elemicin and/or (Z)-isoelemicin). Octyl acetate (57.5-67.1%) was the main constituent of all fruit oils. The antimicrobial activity was screened by a microdilution method against eight bacteria and eight fungi. The strongest antimicrobial effect, in several cases better than the activity of antibiotics, was shown by HSPH (MICs = 0.12-3.30 mg mL-1) and HMON (MICs = 0.10-1.30 mg mL-1) flower oils against bacteria, and HSIB fruit oil against fungi (MICs = 0.15-0.40 mg mL-1). The MTT test revealed that the oils were not or weakly cytotoxic against human malignant HeLa, LS174 and/or A549 cells (except HSPH root oil; IC50 = 5.72-24.31 μg mL-1) and that tested oils were not toxic against human normal MRC-5 cells (at 200.00 μg mL-1). Significant activity observed against microorganisms that are the common cause of foodborne diseases, food contamination and/or hospital-acquired infections justifies certain traditional uses of the investigated plants and represents a good basis for further research of these Heracleum oils.

Abstract
The use of botanicals for maintaining good health and preventing diseases is undisputed. The claimed health benefits of natural health products and herbal medicines are based on traditional claims, positive results obtained in preclinical studies and early phase clinical trials that are not backed by safety and efficacy evidences approved by regulatory agencies. Although, the popularity of botanicals is growing, health care practitioners of modern medicine seldom recommend their use because of ill equipped database of their safety and potency. This review discusses problems that preclude botanicals from integrating into the mainstream contemporary therapeutics and cues that provide impetus for their realisation.

Abstract
Chromatography and spectroscopy techniques are the most commonly used methods in standardization of herbal medicines but the herbal system is not easy to analyze because of their complexity of chemical composition. Many cutting-edge analytical technologies have been introduced to evaluate the quality of medicinal plants and significant amount of measurement data has been produced. Chemometric techniques provide a good opportunity for mining more useful chemical information from the original data. Then, the application of chemometrics in the field of medicinal plants is spontaneous and necessary. Comprehensive methods and hyphenated techniques associated with chemometrics used for extracting useful information and supplying various methods of data processing are now more and more widely used in medicinal plants, among which chemometrics resolution methods and principal component analysis (PCA) are most commonly used techniques. This review focuses on the recent various important analytical techniques, important chemometrics tools and interpretation of results by PCA, and applications of chemometrics in quality evaluation of medicinal plants in the authenticity, efficacy and consistency.

Abstract
PURPOSE Two plant essential oils (EOs), including those from Heracleum transcaucasicum and Heracleum anisactiss (Umbeliferae) were studied to detect the chemical constituents and evaluated for their antibacterial activities against Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli and Pseudomonas aeruginosa. METHODS The EOs of H. transcaucasicum and H.anisactis (Apiacae) were obtained by hydrodistillation from aerial parts of the plants. The chemical analyses of the EOs were performed by GC/Mass spectrometry (GC/MS). Myristicin was found to be the principal constituent in both EOs. The susceptibility tests of EOs were performed by agar disc diffusion technique against Gram-positive and Gram-negative bacterial strains. RESULTS Eight components comprising 99.97% of the total essential oil of H. transcaucasicum and a total of three compounds accounting for 98.5% of the total oil composition of aerial parts of H. anisactis were identified, of which myristicin was the main compound in both EOs. The EOs of H. transcaucasicum and H. anisactis showed weak antibacterial property against Gram-positive strains of Staphylococcus aureus and Staphylococcus epidermidis with no measurable effect on Escherichia coli and Pseudomonas aeruginosa. CONCLUSION Our GC-MS study revealed myristicin to be the major constituent of H. transcaucasicum and H.anisactis aerial parts. In spite of all the information available on the antibacterial properties of plants essential oils, we were not able to find significant antibacterial activity for both EOs.

Abstract
BACKGROUND The aim of this 3-year study was to investigate the effect of different celeriac cultivation strategies on the content of naturally occurring toxicants furanocoumarins, represented by psoralen, bergapten, xanthotoxin and isopimpinellin. The products from organic farming in which anaerobically fermented pig slurry was used were compared against those obtained from other treatment systems: mineral, combined and non-fertilised. RESULTS The average levels of furanocoumarins for all 3 years (determined by gas chromatography-mass spectrometry) in varieties Albin and Kompakt were 2.6 mg kg⁻¹ and 10.2 mg kg⁻¹, respectively. In all crop years higher levels were found in variety Kompakt. By using linear discriminant analysis it was possible to separate the whole data set according to variety from 85.7%, in individual crop years the recognition ability was more than 90%. According to the crop year, it was possible to separate tested samples from 70.8%, for individual variety the separation was 100%. CONCLUSIONS The method of fertilisation did not have a significant effect on the levels of plant secondary metabolites, furanocoumarins. The climatic conditions, in particular the growing periods and the celeriac variety, had an important role in the occurrence of furanocoumarins.

Abstract
Biological chromatographic fingerprinting is a relatively new concept in the quality control of herbal samples. Originally it has been developed with the application of HPLC, and recently herbal samples' biological profiles have been obtained by means of thin-layer chromatography (TLC). This paper summarizes the application of liquid chromatographic techniques for the purpose of biological fingerprint analysis (BFA) of complex herbal samples. In case of biological TLC fingerprint, which is a relatively novel solution, perspectives of its further development are outlined in more detail. Apart from already published data, some novel results are also shown and briefly discussed. The paper aims at drawing scientists' attention to the unique solutions offered by biological fingerprint construction.

Abstract
Coumarins are nowadays an important group of organic compounds from natural sources that are useful in a number of fields. Because they possess different pharmacological properties, finding the proper extraction conditions for their separation from plant matrices is a very important step. In this report Pressurized Liquid Extraction (PLE) under different temperature conditions and with different types of extraction solvents were tested. As a matrix, fruits of Heracleum leskowii have been used. A simple reverse phase high-performance liquid chromatographic method (RP-HPLC) coupled with a photodiode array detector (DAD) has been developed for separation and quantitative analysis of the main coumarins. Umbelliferone, xanthotoxin, angelicin, isopimpinellin, bergapten, imperatorin and isoimperatorin were investigated. Bergapten and imperatorin were dominant in almost all extracts in the range of 9.92 ± 0.02–20.93 ± 0.06 and 12.19 ± 0.98–19.07 ± 0.03 mg/100 g, respectively. Dichloromethane and methanol were chosen as the most proper suitable solvents for extraction of coumarins. By increasing the temperature the amount of extracted coumarins increases in petroleum ether and dichloromethane extracts.

Abstract
Superhydrophobic monolithic porous polymer layers with a photopatterned hydrophilic channel have been prepared. These layers were used for two-dimensional thin layer chromatography of peptides. The 50 microm thin poly(butyl methacrylate-co-ethylene dimethacrylate) layers supported onto 4.0 x 3.3 cm glass plates were prepared using UV-initiated polymerization in a simple glass mold. Photografting of a mixture of 2-acrylamido-2-methyl-1-propanesulfonic acid and 2-hydroxyethyl methacrylate carried out through a mask afforded a 600 microm wide virtual channel along one side of the layer. This channel, which contains ionizable functionalities, enabled the first dimension separation in ion exchange mode. The aqueous mobile phase migrates only through the channel due to the large difference in surface tension at the interface of the hydrophilic channel and the superhydrophobic monolith. The unmodified part of the layer featuring hydrophobic chemistry was then used for the reversed phase separation in the orthogonal second dimension. Practical application of our technique was demonstrated with a rapid 2D separation of a mixture of model peptides differing in hydrophobicity and isoelectric point using a combination of ion-exchange and reversed phase modes. In the former mode, the peptides migrated 11 mm in less than 1 min. Detection of fluorescently labeled peptides was achieved through UV light visualization. Separation of the native peptides was monitored directly using a desorption electrospray ionization (DESI) source coupled to a mass spectrometer. Unidirectional surface scanning with the DESI source was found suitable to determine both the location of each separated peptide and its molecular mass.
