Biological activities of the fruit essential oil, fruit, and root extracts of ferula drudeana korovin, the putative anatolian ecotype of the silphion plant

In the present study, preliminary phytochemical investigations were performed on the fruit essential oil and antioxidant-rich methanolic extracts of the fruits and roots of Ferula drudeana, the putative Anatolian ecotype of the Silphion plant, to corroborate its medicinal plant potential and identify its unique characteristics amongst other Ferula species. The essential oil from the fruits of the endemic species Ferula drudeana collected from Aksaray was analyzed by GC and GC/MS. The main components of the oil were determined as shyobunone (44.2%) and 6-epishyobunone (12.6%). The essential oil of the fruits and various solvent extracts of the fruits and roots of F. drudeana were evaluated for their antibacterial and anticandidal activity using microbroth dilution methods. The essential oil of the fruits, methanol, and methylene chloride extracts of the fruits and roots showed weak to moderate inhibitory activity against all tested microorganisms with MIC values of 78–2000 µg/mL. However, the petroleum ether extract of the roots showed remarkable inhibitory activity against Candida krusei and Candida utilis with MIC values of 19.5 and 9.75 µg/mL, respectively. Furthermore, all the samples were tested for their antioxidant activities using DPPH• TLC spot testing, online HPLC–ABTS screening, and DPPH/ABTS radical scavenging activity assessment assays. Methanolic extracts of the fruits and roots showed strong antioxidant activity in both systems

New chromosomal data, karyotype asymmetry and polyploid variations of some Gundelia (Asteraceae) species from Turkey

The genus Gundelia is currently represented with 18 species, of which 16 are in Turkey. In genus Gundelia, the chromosomal data were reported from 12 species. In the present study, it is aimed to eliminate the deficiencies in the knowledge about chromosomal data of Gundelia species. In Genus Gundelia, only a single chromosome number had been detected as 2n=18 so far. The chromosome numbers of four species were reported here for the first time: G. armeniaca, G. cappadocica, G. siirtica, and G. tehranica. In addition, the polyploidy in the genus was rare and G. anatolica was identified as the first polyploid species. All karyotypes except G. tehranica were symmetrical, consisting of metacentric and submetacentric chromosomes. Secondary constrictions were observed in the distal regions of the long arms of the longest metacentric and submetacentric chromosomes. Thus, the chromosomal data of all Turkish Gundelia species were completed. In conclusion, the present study presented new data into the karyological records relating the karyotype evolution and interspecific relations of genus Gundelia

Cytotoxic activity of the root and fruit extracts of Heptaptera anisoptera (DC.) Tutin

Cytotoxic activities of the root and fruit extracts of Heptaptera anisoptera (DC.) Tutin were investigated on the colon cancer COLO205 and KM12 cell lines. The dichloromethane extract of the roots of H. anisoptera showed cytotoxic activity with IC50 values of 3.1 and 3.9 ug/mL on the COLO205 and KM12 cell lines, respectively. Cytotoxic activity of the dichloromethane extract of the fruits were similar to those of root extract with IC50 values of 5.5 and 4.8 ug/mL on the COLO205 and KM12 cell lines, respectively

Biologically active sesquiterpenes from the indigenous ferula species (Apiaceae) of Turkey

Annual Meeting of the American-Society-of-Pharmacognosy on Natural Products at a Crossroad - Current and Future Directions -- JUL 14-17, 2013 -- St Louis, MOWOS: 000338695100236The genus Ferula comprises more than 180 species and is the largest genus of Apiaceae in Asia. There are 23 species of Ferula in Turkey and 17 of them are endemic. Ferula species are rich sources of sesquiterpenes with wide structural variety. The phytochemical investigations of several Ferula species growing in Turkey has yielded many sesquiterpenes with antibacterial, antifungal, anticancer, antioxidant, P-glycoprotein inhibitor, immune modulator and hormonal activities. Chemical structures, chemical transformations, biological activities, biosynthetic and chemotaxonomic significance of the sesquiterpenes isolated from Anatolian Ferula species will be presented.Amer Soc Pharmacognos

Next Chapter in the Legend of Silphion: Preliminary Morphological, Chemical, Biological and Pharmacological Evaluations, Initial Conservation Studies, and Reassessment of the Regional Extinction Event

Silphion was an ancient medicinal gum-resin; most likely obtained from a Ferula species growing in the Cyrene region of Libya ca. 2500 years ago. Due to its therapeutic properties and culinary value, silphion became the main economic commodity of the Cyrene region. It is generally believed that the source of silphion became extinct in the first century AD. However, there are a few references in the literature about the cultivated silphion plant and its existence up to the fifth century. Recently, a rare and endemic Ferula species that produces a pleasant-smelling gum-resin was found in three locations near formerly Greek villages in Anatolia. Morphologic features of this species closely resemble silphion, as it appears in the numismatic figures of antique Cyrenaic coins, and conform to descriptions by ancient authors. Initial chemical and pharmacological investigations of this species have confirmed the medicinal and spice-like quality of its gum-resin supporting a connection with the long-lost silphion. A preliminary conservation study has been initiated at the growth site of this rare endemic Ferula species. The results of this study and their implications on the regional extinction event, and future development of this species will be discussed

Whereas, the ethyl acetate extract of the fruits showed moderate cytotoxic activity with IC50 values of 23.4 ug/mL against the KM12 cell lines

Microbiologically Catalyzed Enantio- and Diastereoselective Oxidation of Chrysanthemol Stereoisomers to Chrysanthemic Acids

The diastereo- and enantioselective microbial oxidation of a mixture of racemic cis/trans-chrysanthemols to the corresponding stereoisomeric chrysanthemic acids by Aspergillus species is described. Of the three microorganisms which were found capable of oxidizing racemic cis/trans-chrysanthemols, A. ochraceus ATCC 18500 showed complete enantioselectivity for (+)-stereoisomers [(+)-trans-chrysanthemol and (+)-cis-chrysanthemol), whereas A. flavipes ATCC 1030 and ATCC 11013 showed complete enantioselectivity for the (+)-cis-chrysanthemol but a time-dependent enantioselectivity during oxidation of trans-chrysanthemol [oxidation of (+)-trans-chrysanthemol prior to (−)-trans-chrysanthemol]. The diastereoselectivity of all three microorganisms was time dependent, in that the trans-stereoisomers were oxidized prior to the cis-isomers

Anatolicin, a highly potent and selective cytotoxic sesquiterpene coumarin from the root extract of heptaptera anatolica

WOS: 000465503800115PubMed ID: 30909537Seven known sesquiterpene coumarins and a new sesquiterpene coumarin, anatolicin (8), were isolated from the dichloromethane extract of the roots of Heptaptera anatolica. Structures of these compounds were elucidated based on their spectral properties. While some of these sesquiterpene coumarins showed modest cytotoxic activity against COLO205, KM12, A498, UO31, and TC32 cancer cell lines, selective cytotoxicity of anatolicin (8) and 14-acetoxybadrakemin (7) were observed at nanomolar level against the UO31 kidney cancer cell line.Intramural Research Program of the NIH, National Cancer Institute, Center for Cancer Research [1ZIA BC01146907]; National Cancer Institute, National Institutes of Health [HHSN261200800001E]This research was supported in part by the Intramural Research Program of the NIH, National Cancer Institute, Center for Cancer Research (1ZIA BC01146907) and with federal funds from the National Cancer Institute, National Institutes of Health, under contract HHSN261200800001
