“…Different types of biological activities such as anxiolytic (Sufka et al 2001), antimicrobial (Basbulbul et al 2008), antiviral, and expectorant (Kati et al 2001) have been reported for several species of Primula. Previous phytochemical studies on Primula species led to isolation of phenolic compounds and flavonoids (Vitalini et al 2011), saponins (Okrslar et al 2007), carotenoids (Yamamizo et al 2011) and essential oil (Nan et al 2002).…”

Primula heterochroma is indigenous to Caspian coast forests in the north of Iran. Total phenols, total flavnoids, total carotenoids and antioxidant capacity of 50 P. heterochroma accessions were investigated. The highest total phenol (1272.31 mg GA equivalent/100 g fresh weight) and total flavonoids (615 mg catechin/100 g fresh weight) were observed in G5 accession from Saravan. The highest antioxidant activity was observed in G14 accession (73.03 %) from Kacha, followed by G2 accession (69.75 %) and G5 accession (66.84 %) from Saravan. The results of HPLC analysis showed that quercetin-3-glucoside was the major phenolic compound widely found in these accessions followed by chlorogenic acid. There was a linear relationship between the antioxidant capacities and the total phenols and total flavonoid. Inversely, there was no statistically significant correlation between total carotenoid and antioxidant activity. Based on the path coefficient analysis, the maximum direct effect on antioxidant was observed in total phenols (0.908). In addition, the cluster analysis based on Euclidean distance with Unweighted pair-group method using arithmetic average (UPGMA) method separated the accessions into four main groups. Our results supported that Iranian wild primrose accessions possess valuable antioxidant properties for therapeutic and potential medicinal use.

“…The EOs and FAMEs of some Primula species have been mentioned in the literature [6][7][8]. Many studies have shown that the EOs and the components of the plants can be influenced by environmental factors such as soil, temperature, light and altitude.…”

“…The obtained crude EOs of Pvv and Pvs were analyzed by GC-MS with an HP-5 column. Identification of the compounds was made by a typical library search (NIST and Wiley 7NL) and literature comparison [6][7][8][9][10]20]. The general chemical profile of the EOs, the percentage content, and retention indices of the constituents are summarized in Tables 1 and 2.…”

In this study, the changes caused by variation of altitude to the essential oils (EOs), fatty acid methyl esters (FAMEs), and antimicrobial activities of Primula vulgaris Huds. subsp. vulgaris (Pvv) and P. vulgaris Huds. subsp. sibthorpii (Hoffmanns) W.W.Sm. & Forrest (Pvs)) grown in Turkey were investigated. Major fluctuations in the composition of Pvv and Pvs oils included methyl-4-methoxy salicylate (4.5-35.3%;

“…Recent research suggests that the presence of primin in P. obconica may be a result of cultivation: Na et al investigated the volatile oil of wild P. obconica collected from its origin in central China, and they concluded that the native plants seemed to be nonallergenic due to the absence of both primin and miconidin (12). Furthermore, it has been shown that the ability of P. obconica to make primin is controlled by one gene (13) and that it is possible to produce the so‐called primin‐free P. obconica cultivars by breeding (7).…”

Several chemical and clinical observations have suggested the presence of at least one more allergen in addition to primin in Primula obconica. The aim of this study was to investigate the allergenicity of the primin precursor miconidin and the related miconidin methyl ether, both isolated from P. obconica. 12 primin-positive persons were patch tested with miconidin 0.01% petrolatum (pet.), miconidin in 96% ethanol incorporated into 0.01% pet., and miconidin methyl ether 1.0% pet. All persons were positive to miconidin 0.01% pet., with the strength of reactions very similar to those of the individual primin reactions, and remained inexplicably negative while testing with miconidin in 96% ethanol and pet., while miconidin methyl ether elicited 7 positive reactions. Although both miconidin and miconidin methyl ether may be allergenic only due to their conversion to primin in the skin, the presence of these substances nevertheless has to be taken into account when assessing the allergenicity of new P. obconica cultivars.
