It is considered as the important source of essential oils, for example, menthol, geraniol, eucalyptol, camphor and thymol. Therefore, it is imperative to study these economically important compounds under in vitro conditions for their sustainable and enhanced production. In addition to proven biological activities, essential oils from this family have recently been evaluated for anticancer activities and considered as a source of anticancer drugs. Mechanisms involved in the essential oils-mediated antiproliferative activity include cell cycle arrest, apoptosis and DNA repair mechanisms. Essential oils also act in the reduction of tumors, inhibiting metastasis and as anti-multidrug resistance molecules. The aim of this review is to assess the anticancer properties of essential oils obtained from different members of family Lamiaceae. The available reports on active components of essential oils and their effect on cancer type and cell line have been discussed. Biotechnological studies to improve the production of essential oils have also been highlighted. Various methods have been adopted to obtain essential oils under in vitro conditions from different plant species of family Lamiaceae, and their production is affected by culture conditions, cultivation mode, utilization of nutrient media and plant growth regulators. The literature survey suggests that essential oils obtained from family Lamiaceae have perspective for the development of new alternatives for disease treatment and prevention.

Palynological analysis showed that pollen characters were found as small to medium size, isopolar, radially symmetrical, oblate-spheroidal and prolatespheroidal, tricolporate and echinate-perforate ornamentation in the three species. Achene characters were found dark brown to yellow in colour, often cylindrical, compressed, with thickened margin, obovate orobovoid shaped, pappus absent and the coat ornamentations are rectangular with short hairs on the surface. As a result of this study, leaf morphology and some pollen characteristics such as pollen size, shape, perforation and distance between spines were demonstrated to be different among the Bellis species.

In the present study, molecular phylogeny of genus Adonis L. from Turkey was evaluated with the aid of nrDNA ITS. Methods Samples of 10 natural Adonis taxa belonging to 21 different populations including 64 Adonis ecotypes were collected from different regions of the country during vegetation period between 2014 and 2018. ITS1, ITS4, P16 and P25 primers within Internal Transcribed Spacer (ITS) technique were used to estimate infraspeci c variation in different populations of Adonis species. Results We identi ed about 600 bp DNA sequences were obtained from 21 different populations including 64 Adonis ecotypes. The dendrogram obtained from Adonis species and out-group sequences had two large main groups. While the out-group species were placed in the rst large main group, the sect. Consiligo (perennial) and sect. Adonis (annuals) were placed in different subgroups of the second large main group. Genetic similarity among Adonis species varied between A. microcarpa and A. dentata (98.46%). Conclusions Present analyses revealed that phylogenetic classi cation (grouping) of Adonis taxa largely depended on morphological structure and present ITS primers were quite e cient in putting forth the genetic diversity of such species. The results obtained from molecular data can be used to explore the genetic variation pattern, population structure, and the evolutionary history of natural Adonis species in the future.

Botanically, Ranunculaceae comprises vital medicinal plants. Molecular markers are one of the most effective tools for exploring genetic variation that can enhance breeding efficiency. To identify the genetic diversity of 62 Adonis ecotypes collected from different regions in Turkey, the interprimer binding site (iPBS) retrotransposon system was used. Of the 83 iPBS primers used, 10 provided sufficient polymorphic data, generating a total of 204 alleles. The number of iPBS bands per individual was 3.29, and the number of alleles per polymorphic locus ranged from 8 to 35, with an average of 20.30. The average polymorphism percentage was 99.50%, and polymorphic information content ranged from 0.16 to 0.39. The highest average number of alleles, Nei's genetic diversity (h), and Shannon's information index (I) were obtained from A. volgensis species (1.64, 0.39, and 0.58, respectively), whereas the lowest values (1.41, 0.29, and 0.46, respectively) were found in A. flammea species. The analysis of molecular variance revealed significant variance within the population (71%), whereas no significant genetic variation was observed among the different species (29%). Cluster analysis according to unweighted pair-group mean average (UPGMA) divided 62 Adonis ecotypes into four major clusters. According to the principal coordinate analysis, the first three principal coordinates accounted for 81.51% of total variation. Genetic structure analysis of the studied germplasm using the Bayesian method revealed four subpopulations with an average of 0.2634 for expected heterozygosity and 0.2154 for population differentiation measurements. The results of this study suggested that iPBS markers could be used in the identification of genetic diversity among the Adonis species.

Ultraviyole radyasyon içeriği, mevsim, tropik, gün uzunluğu, rakım ve belirli atmosferik koşullar gibi bazı faktörlere bağlıdır. Uzun süreli güneş ışığına (UV ışınlarına) maruz kalmanın, güneş çarpması, güneş yanığı ve cilt kanseri gelişimi ile ilişkili olduğu bilinmektedir. UV ışınlarının emilmesi, yansıması ve dağılımı için yaygın olarak kullanılan birçok sentetik ürün vardır, ancak kimyasal ilaçlar insan vücudunda irritan kontakt dermatit, fototoksisite ve fotoalerji gibi bazı yan etkilere neden olur. Bitkisel ilaçlar, birçok halk sağlığının tedavisinde veya önlenmesinde popülerlik kazanmıştır. Bu çalışma, zararlı UV ışınlarından kaynaklanan güneş çarpması ve güneş yanığı hastalıklarının tedavisinde ve önlenmesinde önemli çeşitli tıbbi ve aromatik bitkilere genel bir bakış sunmaktadır. Bu bitkilerin bilimsel isimleri ve kullanılan kısımları detaylı olarak listelenmiş ve 29 farklı bitki taksonu belirlenmiştir. En sık olarak kullanılan bitkiler şu şekildedir: Juglans regia, Teucrium polium, Arctium minus ve Cornus mas'dır. Son olarak, elde edilen bulgular, geleneksel tıbba ilişkin daha sonraki çalışmalara ve Türkiye'deki allopatik tıbba katkısı için bir temel olarak kullanılabilir.
