“…Echium plantagineum L., native to southern Europe, is known by its characteristic flower with a purple corolla and two protruding stamens and one stigma, thus being commonly known as purple viper's bugloss (Figure 1). This species is visited by bees especially at the end of the floral period and dark blue bee pollen pellets (Figure 1) are then collected and commercialized [1]. Furthermore, pollen from Echium species is commonly found in honeys [2].…”

Oxidative stress and inflammation play important roles in disease development. This study intended to evaluate the anti-inflammatory and antioxidant potential of Echium plantagineum L. bee pollen to support its claimed health beneficial effects. The hydromethanol extract efficiently scavenged nitric oxide (•NO) although against superoxide (O2 •−) it behaved as antioxidant at lower concentrations and as pro-oxidant at higher concentrations. The anti-inflammatory potential was evaluated in LPS-stimulated macrophages. The levels of •NO and L-citrulline decreased for all extract concentrations tested, while the levels of prostaglandins, their metabolites and isoprostanes, evaluated by UPLC-MS, decreased with low extract concentrations. So, E. plantagineum bee pollen extract can exert anti-inflammatory activity by reducing •NO and prostaglandins. The extract is able to scavenge the reactive species •NO and O2 •− and reduce markers of oxidative stress in cells at low concentrations.

“…However, the pigmentation of pollen may influence its resistance to abiotic stress. Pollen is pigmented with flavonoid compounds in many taxa (Mo et al ., ; Lunau, ), and anthocyanins have been detected in the pollen of some species (di Paola‐Naranjo et al ., ; Leja et al ., ). When disrupted, chalcone synthase, the first enzyme in the anthocyanin biosynthetic pathway, yields pollen‐sterile individuals in both Petunia and Maize (Coe et al ., ; Mo et al ., ; Napoli et al ., ).…”

Geographic variation in pollen color is associated with temperature stress

The evolution of flower color, especially petal pigmentation, has received substantial attention. Less understood is the evolutionary ecology of pollen pigmentation, though it varies among and within species and its biochemical properties affect pollen viability. We characterize the distribution of pollen color across 24 populations of the North American herb Campanula americana, and assess the degree to which this variation is genetically based. We identify abiotic factors that covary with pollen color and test whether germination of light and dark pollen is differentially affected by variable temperature and UV. Pollen color varies from white to deep purple in C. americana and is genetically determined. There was a longitudinal cline whereby pollen was darkest in western populations. Accounting for latitudinal variation, western populations experience elevated temperature and UV irradiance. Germination of light-colored pollen was reduced by 60% under high temperature, but dark pollen was unaffected. Exposure to UV reduced germination of light and dark pollen similarly. The cline in pollen color across the range may reflect adaptation to heat stress. This study supports thermal tolerance as a novel function of pollen pigmentation and contributes to growing evidence that abiotic factors can drive floral diversity.

“…It is considered to be a natural health food which constitutes a potential source of energy and functional components for human consumption (Silva et al, 2006). A number of bioactive substances in bee pollen such as phenolics, flavonoids, anthocyanin, phospholipids and proteins have been reported (Nagata et al, 2005;Napoli et al, 2006;Di Paola-Naranjo, Sánchez-Sánchez, González-Paramás, & Rivas-Gonzalo, 2004;Tomas-Lorente, Garcia-Grau, Nieto, & Tomas-Barberan, 1992;Ukiya et al, 2003). Recently, increasing evidences prove its potential therapeutic benefits, such as free radical scavenging activities (Campos, Webby, Markham, Mitchall, & Da Cunha, 2003;Leja, Mareczek, Wyżgolik, Klepacz-Baniak, & Czekońska, 2007;Nagai, Inoue, Inoue, & Suzuki, 2002;Silva et al, 2006), inhibition of lipid peroxidation (Almaraz-Abarca, Campos, Ávila-Reyes, Naranjo-Jiménez, Corral, & González-Valdez, 2007) and suppressing the cellular and humoral response (Qin & Sun, 2005;Yuan & Xu, 1996).…”
