Bu çalışmada Diospyros kaki L. (Trabzon hurması) meyvesinin kabukları ile hazırlanan metanol, etanol ve su ekstraktları kullanılarak antimikrobiyal, antioksidan kapasiteleri incelenmiştir. Çalışılan örneklerin katalitik aktivitesinin incelenmesi amacıyla sodyum borhidrür (NaBH4) varlığında Metilen Mavisi boyasının indirgenmesi değerlendirilmiştir sonuçlar UV-Visible Spektrofotometresinde (UV-Vi...

Nanopatterns have applications in many areas including sensors, optoelectronics, and crystallization screening. Particle lithography is a convenient method to manufacture nanoring nanopatterns based on organosilane surface chemistry. The pattern thickness is generally limited to the monolayer thickness. This work is focused on the chemical vapor deposition conditions that yield nanopatterns wit...

The phytochemical profile and anti-inflammatory activity of Gaultheria procumbens dry lipophilic leaf extracts were evaluated. Forty compounds were identified by GC-MS, representing 86.36% and 81.97% of the petroleum ether (PE) and chloroform (CHE) extracts, respectively, with ursolic acid (28.82%), oleanolic acid (10.11%), methyl benzoate (10.03%), and methyl salicylate (6.88%) dominating in C...

Lippia dulcis is a sweet-tasting, woody herb but the sweetness is often mixed with a camphorous taste. Lippia dulcis oil from Brazil was found to be low in camphor (trace), whereas the oil from Mexico had considerable camphor (33.9%). The Lippia oil from Brazil was high in 6-methyl-5-hepten-2-one (10.5%), α-copaene (8.6%), (E)-caryophyllene (10.6%), bicyclogermacrene (6.6%), δ-cadinene (7.2%), ...

BACKGROUND Lysimachia paridiformis Var. Stenophylla mainly contain flavonoid constituents. Flavonoids and benzoquinones are the main compounds in L. fortumei Maxim. The objective of this paper was to study the volatile compounds of leaves in L. paridiformis Var. Stenophylla, L. fortumei and L. chikungensis for the first time. MATERIALS AND METHODS Volatiles were extracted by the manual solid ...

Social arthropods such as termites, ants, and bees are among others the most successful animal groups on earth. However, social face an elevated risk of infections due to dense colony structure, which facilitates pathogen transmission. An interesting hypothesis is that protected by chemical compounds produced themselves, microbial symbionts, or plants they associate with. Stegodyphus dumicola A...

The genus Rhodococcus is gram positive bacterium which was classified into the family of Nocardiaceae.  The organism can be isolates from different sources, with capability to degrade diverse types of pollutant. Nowadays, scientists reported a few secondary metabolites which are produced by Rhodococci. Hence, the present study tried to isolate Rhodococci from different soil samples with the cap...
