Pihlajanmarjasta (S. aucuparia) tieteellistä tietoa

Ensinnäkin nimestä

  1.  Tavallinen pihlaja, Sorbus aucuparia,  vanlig rönn. 

  2.  Sorbus aria, Saksanpihlaja, jättevitoxel 

  3. Sorbus intermedia, S. suecica , Ruotsinpihlaja, oxel   

Ruotsinpihlaja (Sorbus intermedia) on Etelä-Ruotsissa ja lounaisimmassa Suomessa kasvava, muuallakin puistopuuna yleinen pihlajalaji. Alkujaan Linné antoi sille tieteellisen nimen S. suecica. Ruotsinpihlaja on saanut alkunsa kotipihlajan, etelänpihlajan ja saksanpihlajan[2] tai jonkin sen läheisen sukulaislajin risteymänä.

Sorbus aucuparia and Sorbus aria as a Source of Antioxidant Phenolics, Tocopherols, and Pigments. Šavikin KP et al. Chem Biodivers. (2017)
 Abstract
Due to its nutritive and medicinal properties, berries of some Sorbus species are used for the preparation of jams and jelly as well as in traditional medicine. On the other hand, their chemical composition is not much studied especially of those grown in Balkan Peninsula. We have analyzed individual phenolics, tocopherols, carotenoids and chlorophylls using HPLC in berries from Sorbus aucuparia and Sorbus aria collected in different localities in Serbia and Montenegro together with the amounts of total phenolics and proanthocyanidins as well as their radical scavenging activity against DPPH radical.
Berries of S. aucuparia were richer source of polyphenolics in comparision with S. aria and, regardless the species and locality, caffeoylquinic acids such as neochlorogenic and chlorogenic acid were the most abundant compounds.
 Among analyzed tocopherols the most abundant in all samples was α-tocopherol (0.48 - 19.85 μg/g dw) as it was β-carotene among carotenoids (mean concentration of 0.98 μg/g dw in S. aucuparia and 0.40 μg/g dw in S. aria, respectively). Correlation between total phenolics and DPPH radical scavenging activity was noticed. Our study represents comprehensive report on chemical composition of S. aucuparia and S. aria which could contribute to a better understanding of their quality.

Research in the chemical composition of the bark of Sorbus aucuparia. Krivoruchko E et al. Ceska Slov Farm. (Wint)Abstract
The quantitative contents of 40 carboxylic acids, with the prevalence of hexadecanedioic, lignocerinic, behenic, azelaic, palmitic and benzoic acids, and 39 components of essential oil were determined in the extracts of the bark of Sorbus aucuparia by the GC-MS method. The quantitative contents of 6 phenolic compounds, i.e., chlorogenic, caffeic, and gallic acids, catechin, quercetin, and apigenin-7-glucoside were determined by the HPLC method in the ethanolic extract of the bark of Sorbus aucuparia. Key words: Sorbus aucuparia bark, carboxylic acids, phenolic compounds, essential oil, GC-MS, HPLC.

 
Antitumor Effects of Sorbus aucuparia L. Extract Highly Saturated with Anthocyans and Their Mechanisms. Razina TG et al. Bull Exp Biol Med. (2016) Abstract
The effects of Fructus Sorbi aucupariae extract, originally saturated with anthocyans, on the development of Lewis lung carcinoma and B-16 melanoma in C57Bl/6 mice and the efficiency of cyclophosphamide treatment were studied. Antitumor activity of the extract and potentiation of the antimetastatic activity of the cytostatic were demonstrated. Studies on melanoma B-16 model revealed an increase in the counts of stromal progenitor cells in the tumor node and their accelerated maturation after treatment with the extract. No effects towards the tumor stem and committed cells were detected.KEYWORDS:B-16 melanoma; Fructus Sorbi aucupariae; Lewis lung carcinoma; anthocyans; tumor stem cells PMID: 27878717 DOI: 10.1007/s10517-016-3554-4
