Primula Dermatitis

Primula allergic dermatitis simulating occupational contact dermatitis induced by metals, oils and greases.

A case of the hands and face dermatitis in a patient employed in a store with motor-car spare parts is presented. Both the patient and her doctor were convinced that skin lesions were caused by the contact with metals, oils and greases. After detecting allergy to primine (after 48 and 96 h, + +), the patient recalled that two months earlier she had started to grow primrose (Primula obconica) at...

Primula Culture and Production

The name Primula or primrose is derived from the word primary or first, referring to the early growth and flowering in spring (Liberty Hyde Bailey Hortorium, 1976). More than 400 species of primula exist in the family Primulaceae (Griffiths, 1994). Other important horticultural genera in this family, besides primula, include pimpernel (Anagallis), rock jasmine (Androsace), persian violet, alpin...

Farinose alpine Primula species: phytochemical and morphological investigations.

This work investigated the epicuticular and tissue flavonoids, the volatiles and the glandular trichome structure of the leaves of four species of Primula L. that grow in the Italian Eastern Alps. Primula albenensis Banfi and Ferlinghetti, P. auricula L., P. farinosa L., P. halleri Gmelin produce farinose exudates that are deposited on the leaf surface as filamentous crystalloids. In addition t...

Genetic Variation in Natural and Cultivated Populations of Primula Veris

Primula veris, a well-known pharmaceutical plant, is a long-lived perennial protected by law in Poland, so its rhizomes and roots can be collected as pharmaceutical stock only from cultivation. Genetic variation of three natural P. veris populations numbering 500–1200 individuals and of three cultivated populations derived from seeds collected from natural sites was investigated in respect of t...
