Moderate effects of some plants with proven biological properties in the treatment of various diseases have increased the importance of them and the interest in alternative medicine. The members of the Lamiaceae family are one of the widely used in alternative medicine and agriculture due to their metabolite content. In order to gain valuable biological data for alternative medicine and new studies, Scutellaria albida subsp. Candensest a member of the Lamiaceae family was collected from a height of 1500 meters in Bitlis province in Turkey. Ethanol (EtOH) extract was prepared by using the aerial parts of the plant and used in all stages of the study. Firstly, the phenolic content of the extract was determined by HPLC. Myricetin and 4-Hydroxybenzoic acid at the highest concentrations were detected, but ascorbic acid, gallic acid, quercetin, and 3,4-Dihydroxybenzoic acid could not be determined in the extract. In order to test the antioxidant properties based on phenolic content, several in vitro antioxidant tests were performed and DNA protective properties were investigated. In the biological activity results, the extract was determined to have a similar antioxidant effect to standards or lower than them and exhibited relatively DNA protective activity at high concentration. Finally, the effects of the extract on some types of bacteria and fungi were investigated by the hollow agar method and 150 µL volume of the extract was shown to have better activity than ampicillin and Amikacin. Due to the limited studies on Scutellaria albida subsp Candensest, it is thought that this study will contribute to the literature.

In this research, the genera Asperula L., Galium L.; Asperula xylorrhiza Nábelek (siirt belumotu), Asperula orientalis Boiss. & Hohen. (gökçe belumotu), Asperula arvensis L. (tarla belumotu), Galium humifusum M.Bieb. (çimen iplikçiği), Galium consanguineum Boiss. (altın iplikçik), Galium incanum L. subsp. elatius (Boiss.) Ehrend.(gür iplikçik), Galium consanguineum Boiss. (altın iplikçik), Galium mite Boiss. & Hohen. (süpürge iplikçiği), Galium spurium L. subsp. spurium (arsız iplikçik) of the family Rubiaceae, have been studied in terms of palynological properties. Examples of these taxa were collected in the field studies. 9 taxa light microscopy (IM) and scanning electron microscopy (SEM) belonging to this family were studied. As a result of this study some common traits of the taxa found out such as pollen the tectum is perforated, apertures type is zonocolpate.

Bu çalışmada, Bitlis’te yetişen bazı bitkilerde doğal olarak bulunan radyo izotop konsantrasyon seviyeleri belirlendi. Numuneler, NaI(Tl) gama ışını spektrometresi kullanılarak analiz edildi. Bu bitkilerde, 226Ra radyo izotop aktivite konsantrasyon seviyelerinin 12,45 ± 2,53 Bq/kg ile 92,08 ± 5,34 Bq/kg arasında, 232Th radyo izotop konsantrasyon seviyelerinin 23,10 ± 4,42 Bq/kg ile 88,00 ± 6,68 Bq/kg arasında, 40K radyo izotop konsantrasyon seviyelerinin 42,57 ± Bq/kg ile 533 ± 7,78 Bq/kg arasında değiştiği görülmüştür.
