“…Locally, it has an acceptable flavor and of highly nutritive seasonal food. Akyüz M. (2013) found that desert truffle (DT) is rich in linoleic, oleic and palmitic acids, and rich in flavonoids that make it showing a high free radical scavenging activity. In a different study, there was a correlation between antioxidant and antiradical activities of dried desert truffles from four different Middle Eastern countries and phenolic contents (Al-Laith, 2010).…”

Different kinds of natural food ingredients could be in making yoghurt to produce palatable and more healthy fermented milk. Desert truffle is a popular nutritious food that showed a work was to produce healthy yoghurt supplemented with dessert truffle powder (DTP). Stirred yoghurt was prepared from cow's milk standardized to 3% fat and supplemented with dried DTP at levels of 1, 3 and 5% prior to inoculation with yoghurt culture. Resultant stirred yoghurt was analyzed when fresh and after 3, 6, and 9 days of the cold storage. Chemical composition of yoghurt milk showed an increased protein and total solids contents. Stirred yoghurt with DTP showed a reduction in both apparent viscosity as well as syneresis during storage period. Sensory evaluation revealed that 1% DTP is the most acceptable stirred yoghurt compared to 3 and 5% DTP treatments. There was a correlation between content of phenolic compounds in stirred yoghurt and both quantity of DTP and antioxidant activity. In sum, a healthy stirred yoghurt can be produced by addition of DTP which increased content of phenolic compounds and antioxidant activity of the stirred yoghurt. The highest sensory scores were accounted for 1% DTP.

“…When the groups were compared in terms of concentration, the highest level of free radical scavenging effect at the group, to which we added a 100 μL sample, was seen at T. boudieri with 8.00% (Table 2). It seems that the radical scanvenging activity of T. boudieri might be different than what was expressed in an earlier published report [9,12,17,23,[37][38]. Bioactive compounds and antioxidant activity of mushrooms depend on its relation with the strain/type, the ascocarp size, harvest time, host plant, and the ecocystems.…”

Trichophyton sp.'nin gelişmelerini değişik oranlarda (8-22 mm çap) inhibe ettiği ve DPPH radikalini giderme etkisinin ise 25 μL (% 1.22-2.58), 50 μL (% 2.31-3.28) ve 100 μL (% 5.24-8.00) örnek eklenen gruplarda daha etkili olduğu tespit edilmiştir. Terfezia türlerinden elde edilen metil alkol özütlerinin, test mikroorganizmalarına karşı Picoa türlerinden daha etkili olduğu tespit edilmiştir. Derişime bağlı olarak gruplar karşılaştırıldığında ise 100 μL örnek eklediğimiz grupta en fazla serbest radikal giderme etkisi % 8.00 ile T. boudieri'de görülmektedir. Anahtar Kelimeler Antimikrobiyal aktivite, antioksidant özellik, kurak-yarı kurak trüfler, yenen mantar, Terfezia, Picoa.

Desert truffles have high nutritional value and grow wild in the Mediterranean basin and Western Asia. Although, many studies were performed to evaluate truffles nutritious values and phytochemical composition, studies are limited to evaluate their anticancer and/ or immunomodulatory effects. Our study was conducted to evaluate the anticancer and immunomodulatory effects of Terfezia boudieri (desert truffle). Different solvent extracts were prepared from the truffle and MTT assay was used to measure their anticancer activity against cancer cell lines (T47D, MCF-7, MDA-MB231, HCT-116, and Hela). Total phenolic content in each extract was determined by using Folin-Ciocalteu reagent and qualitative phytochemical screening was performed using standard methods. The degree of apoptosis induction (using caspase 3 assay) and vascular endothelial growth factor expression were detected using standard kits. Also, ELISA was used to measure levels of IFN-γ, IL-2, IL-4, and IL-10 secreted by splenocytes after treatment with the extracts. The effect of the extracts on splenocytes proliferation was measured using MTT assay. Macrophage function was evaluated using nitro blue tetrazolium assay and pinocytosis function was evaluated using neutral red method. Terpenoids, phytosterols, and carbohydrates were present in all the solvent extracts, while tannins, alkaloids and flavonoids were detected only in aqueous/methanol and aqueous extracts. The highest total phenolic content was observed in aqueous and aqueous methanol extracts. The growth of cancer cell lines was inhibited by T. boudieri extracts in a dose dependent manner. N-hexane extract was the most potent against most cell lines. Aqueous/methanol extract showed high apoptosis induction and angiogenesis suppression effects. An increase in TH1 cytokines (IFN-γ, IL-2) level and a decrease in TH2 cytokine (IL-4) level were evident after lymphocytes stimulation by aqueous/methanol, n-hexane and ethyl acetate extracts of T. boudieri. Ethyl acetate extract of T. boudieri were the most potent extracts to stimulate lymphocytes proliferation while all other extracts showed moderate stimulation. Aqueous/methanol extract was the most active extract to stimulate phagocytosis. Ethyl acetate extract was the most active extract to stimulate pinocytosis. The use of T. boudieri provides variable health benefits. N-hexane, ethyl acetate, and aqueous/methanol extracts exhibited anticancer activities and are potent stimulators of innate and acquired immunity. Further testing is needed to identify the biologically active compounds and detect them quantitatively using GC-MS analysis.
