Kemijski sastav endemske biljke Centaurea austro-anatolica i ispitivanje antimikrobnog djelovanja protiv multi-rezistentnih bakterija

Hexane, chloroform, ethyl acetate and ethanolic extracts of the aerial parts of C. austro-anatolica Hub.-Mor. (Asteraceae) were evaluated against microorganisms, including multi-resistant bacteria, using a paper disc diffusion method. The chloroform extract exhibited significant antibacterial activity toward all bacteria tested. The chemical composition of the chloroform extract was determined by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The major compounds of the extract were caryophyllene oxide (21.32 %), spathulenol (10.86 %), n-tricosanol (9.58 %) and geranyl isovalerate (8.71 %).Heksanski, kloroformski, etil-acetatni i etanolni ekstrakti vršnih dijelova biljke C. austro-anatolica Hub.-Mor. (Asteraceae) ispitivani su na antimikrobno djelovanje protiv multi-rezistentnih bakterija, koristeći difuzijsku metodu na papirnom disku. Kloroformski ekstrakt pokazao je značajno antibakterijsko djelovanje protiv svih testiranih bakterija. Kemijski sastav tog ekstrakta određivan je plinskom kromatografijom (GC) i plinskom kromatografijom-spektrometrijom masa (GC-MS). Najvažniji sastojci ekstrakta bili su kariofilen oksid (21,32 %), spatulenol (10,86 %), n-trikozanol (9,58 %) i geranil izovalerat (8,71 %)

Berberis Plants—Drifting from Farm to Food Applications, Phytotherapy, and Phytopharmacology

The genus Berberis includes about 500 different species and commonly grown in Europe, the United States, South Asia, and some northern areas of Iran and Pakistan. Leaves and fruits can be prepared as food flavorings, juices, and teas. Phytochemical analysis of these species has reported alkaloids, tannins, phenolic compounds and oleanolic acid, among others. Moreover, p-cymene, limonene and ocimene as major compounds in essential oils were found by gas chromatography. Berberis is an important group of the plants having enormous potential in the food and pharmaceutical industry, since they possess several properties, including antioxidant, antimicrobial, anticancer activities. Here we would like to review the biological properties of the phytoconstituents of this genus. We emphasize the cultivation control in order to obtain the main bioactive compounds, the antioxidant and antimicrobial properties in order to apply them for food preservation and for treating several diseases, such as cancer, diabetes or Alzheimer. However, further study is needed to confirm the biological efficacy as well as, the toxicity

Kemijski sastav te antioksidacijski, citotoksični i insekticidni potencijal valerijane Valeriana alliariifolia u Turskoj

Valeriana is a common plant species used for various healing purposes in folk medicine since antiquity. This study investigates the phytochemical profile, antioxidant, cytotoxic, and insecticidal activity of Valeriana alliariifolia Adams, a species that has traditionally been used in Turkey. For the analyses we prepared four root extracts of V. alliariifolia Adams using hexane (HM1), chloroform (CM1), ethanol (EM1), and water (WM1) for maceration. Additionally, two extracts were also prepared from its roots by maceration separately with ethanol (EM2) and water (WM2). One sample was prepared as a water infusion (WI), according to the procedure used in Turkish traditional medicine. The 2,2-Diphenyl-1-picrylhydrazyl (DPPH) scavenging and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical cation scavenging activity tests showed that ethanol extracts had the strongest antioxidant activity: EM1 (IC50 – DPPH: 17.694 μg/mL; ABTS: 23.8 μg/mL) and EM2 (IC50 – DPPH: 20 μg/mL; ABTS: 21.5 μg/mL). The hexane extract, HM1, was the most cytotoxic (IC50<10 μg/mL against HepG2 and HUVEC) and EM2 strongly cytotoxic (IC50<10 μg/mL against HepG2 and IC50: 11.96 μg/mL against HUVEC). The extracts with demonstrated cytotoxic activities were further examined to check their insecticidal activity against adult female mosquito Aedes aegypti and first instar Ae. aegypti larvae. HM1 was the most effective (90±10 %), which was consistent with its cytotoxic activity. Because of the high antioxidant, cytotoxic, and insecticidal activities, we ran phytochemical analyses of the HM1, EM1, and EM2 extracts with GC-MS (for HM1) and LC-MS/MS (for EM1 and EM2). We also analysed the composition of the essential oil obtained from V. alliariifolia roots by micro-distillation in order to compare its content with HM1, which contains volatile compounds. Phytochemical analyses revealed that the major compound in HM1 was isovaleric acid (16 %) and in the essential oil 1,8-cineole (2.9 %). EM1 and EM2 contained 5-O-caffeoylquinic acid (chlorogenic acid), verbascoside (acteoside), and 3,5-dicaffeoylquinic acid as major components. In the light of our findings and available literature, we can conclude that V. alliariifolia has a good bioactive potential that could be used for different purposes, including the development of new agents for the treatment of various diseases. The difference in the content between the essential oil and HM1 was remarkable. It suggests that the variability observed in the activity of the samples was a result of composition and that, therefore, the aim of treatment should dictate which type of preparation is to be selected. An added value of our study is that it determined verbascoside and methylquercetin rutinoside for the first time in the Valeriana extracts.Valerijana (odoljen) česta je biljna vrsta koja se zbog svojih ljekovitih svojstava od davnina rabi u narodnoj medicini. U ovome se istraživanju utvrdio fitokemijski profil te antioksidacijsko, citotoksično i insekticidno djelovanje tradicionalne vrste koja se za liječenje rabi u Turskoj – Valeriana alliariifolia Adams. Za analizu je maceracijom pripremljeno šest ekstrakata njezina korijena pomoću heksana (HM1), kloroforma (CM1), etanola (EM1, EM2) i vode (WM1, WM2). Jedan je uzorak pripremljen infuzijom vodom (WI) prema tradicionalnom turskom receptu za ljekovite pripravke. Testovima antioksidacijskoga djelovanja pomoću 2,2-difenil-1-pikrilhidrazila (DPPH) i 2,2’-azino-bis(3-etilbenzotiazolin-6-sulfonične kiseline (ABTS) izdvojeni su sljedeći ekstrakti s najjačim antioksidacijskim djelovanjem: EM1 (IC50 – DPPH: 17,694 μg/mL; ABTS: 23,8 μg/mL) i EM2 (IC50 – DPPH: 20 μg/mL; ABTS: 21,5 μg/mL). Ekstrakt s heksanom, HM1, iskazao je najveću citotoksičnost (IC50<10 μg/mL protiv tumorskih stanica HepG2 i HUVEC), a EM2 snažnu citotoksičnost (IC50<10 μg/mL protiv HepG2 stanica te IC50 11,96 μg/mL protiv HUVEC stanica). Ekstrakte s najsnažnijim citotoksičnim djelovanjem također smo analizirali za insekticidno djelovanje protiv odraslih ženki komarca vrste Aedes aegypti te njihovih ličinki. U skladu sa svojom citotoksičnosti, HM1 se pokazao najdjelotvornijim (smrtnost 90±10 %). Zbog snažnog antioksidacijskog, citotoksičnog i insekticidnog djelovanja, napravili smo i fitokemijsku analizu ekstrakata HM1, EM1 i EM2 služeći se metodama GC-MS (za HM1) i LC-MS/MS (za EM1 i EM2). Također smo analizirali sastav esencijalnoga ulja dobivenoga mikrodestilacijom korijena V. alliariifolia kako bismo ga usporedili sa sastavom HM1, koji je sadržavao hlapljive sastojke. Fitokemijska je analiza pokazala da je glavni sastojak HM1 izovalerijanska kiselina (16 %), a esencijalnoga ulja 1,8-cineol (2,9 %). Glavni sastojci ekstrakata EM1 i EM2 bili su 5-O-kafeoilkvinska kiselina (klorogena kiselina), verbakozid (akteozid) i 3,5-dikafeoilkvinska kiselina. U svjetlu ovih rezultata i dostupne literature, možemo zaključiti da V. alliariifolia ima dobar bioaktivni potencijal, koji se može iskoristiti za različite svrhe poput razvoja novih tvari za liječenje bolesti. Razlika u sadržaju između esencijalnoga ulja i ekstrakta HM1 pokazala se golemom te upućuje na to da su razlike u aktivnosti između uzoraka rezultat sastava, zbog čega primjena/liječenje trebaju uvjetovati koja će se vrsta pripravka odabrati. Dodatna je vrijednost ovoga istraživanja što su se u ekstraktima valerijane prvi put otkrili verbaskozid i metilkvercetin rutinozid

Of the importance of a leaf: the ethnobotany of sarma in Turkey and the Balkans

BACKGROUND: Sarma - cooked leaves rolled around a filling made from rice and/or minced meat, possibly vegetables and seasoning plants - represents one of the most widespread feasting dishes of the Middle Eastern and South-Eastern European cuisines. Although cabbage and grape vine sarma is well-known worldwide, the use of alternative plant leaves remains largely unexplored. The aim of this research was to document all of the botanical taxa whose leaves are used for preparing sarma in the folk cuisines of Turkey and the Balkans. Methods: Field studies were conducted during broader ethnobotanical surveys, as well as during ad-hoc investigations between the years 2011 and 2014 that included diverse rural communities in Croatia, Bosnia and Herzegovina, Serbia, Kosovo, Albania, Macedonia, Bulgaria, Romania, and Turkey. Primary ethnobotanical and folkloric literatures in each country were also considered. Results: Eighty-seven botanical taxa, mainly wild, belonging to 50 genera and 27 families, were found to represent the bio-cultural heritage of sarma in Turkey and the Balkans. The greatest plant biodiversity in sarma was found in Turkey and, to less extent, in Bulgaria and Romania. The most commonly used leaves for preparing sarma were those of cabbage (both fresh and lacto-fermented), grape vine, beet, dock, sorrel, horseradish, lime tree, bean, and spinach. In a few cases, the leaves of endemic species (Centaurea haradjianii, Rumex gracilescens, and R. olympicus in Turkey) were recorded. Other uncommon sarma preparations were based on lightly toxic taxa, such as potato leaves in NE Albania, leaves of Arum, Convolvulus, and Smilax species in Turkey, of Phytolacca americana in Macedonia, and of Tussilago farfara in diverse countries. Moreover, the use of leaves of the introduced species Reynoutria japonica in Romania, Colocasia esculenta in Turkey, and Phytolacca americana in Macedonia shows the dynamic nature of folk cuisines. Conclusion: The rich ethnobotanical diversity of sarma confirms the urgent need to record folk culinary plant knowledge. The results presented here can be implemented into initiatives aimed at re-evaluating folk cuisines and niche food markets based on local neglected ingredients, and possibly also to foster trajectories of the avant-garde cuisines inspired by ethnobotanical knowledge

The bear in Eurasian plant names: Motivations and models

Ethnolinguistic studies are important for understanding an ethnic group's ideas on the world, expressed in its language. Comparing corresponding aspects of such knowledge might help clarify problems of origin for certain concepts and words, e.g. whether they form common heritage, have an independent origin, are borrowings, or calques. The current study was conducted on the material in Slavonic, Baltic, Germanic, Romance, Finno-Ugrian, Turkic and Albanian languages. The bear was chosen as being a large, dangerous animal, important in traditional culture, whose name is widely reflected in folk plant names. The phytonyms for comparison were mostly obtained from dictionaries and other publications, and supplemented with data from databases, the co-authors' field data, and archival sources (dialect and folklore materials). More than 1200 phytonym use records (combinations of a local name and a meaning) for 364 plant and fungal taxa were recorded to help find out the reasoning behind bear-nomination in various languages, as well as differences and similarities between the patterns among them. Among the most common taxa with bear-related phytonyms were Arctostaphylos uva-ursi (L.) Spreng., Heracleum sphondylium L., Acanthus mollis L., and Allium ursinum L., with Latin loan translation contributing a high proportion of the phytonyms. Some plants have many and various bear-related phytonyms, while others have only one or two bear names. Features like form and/or surface generated the richest pool of names, while such features as colour seemed to provoke rather few associations with bears. The unevenness of bear phytonyms in the chosen languages was not related to the size of the language nor the present occurence of the Brown Bear in the region. However, this may, at least to certain extent, be related to the amount of the historical ethnolinguistic research done on the selected languages
