“…This profile of flavonoid distribution has been shown also in other stingless bee-pollens as Melipona subnitida (Silva et al 2006), and Scaptotrigona bipunctata (Lins et al 2003). Dihydroquercetin (Strohl and Seikel 1965), isorhamnetin (Tomas-Lorente et al 1992), and luteolin (Campos et al 2002), have already been isolated from pollen. This is however the first report of isorhamnetin-3-O-(6"-O-E-p-coumaroyl) -β-D-glucopyranoside (4) in bee pollen.…”

“…However, it would appear from published work that it is very unusual for aglycones to occur naturally in pollen loads. The few accounts found are those of Wollenweber and Wiermann (1979) who reported the presence of the free chalcone aglycone, and Strohl and Seikel (1965) who found dihydroflavonols. More recently Campos et al (1997Campos et al ( , 2002 and Lins et al (2003) reported the presence of flavones and flavonols.…”

“…It is of interest therefore that all flavonoids found here in pollen loads of M. subnitida are aglycones. Furthermore, selagin is reported as a pollen constituent for the first time and the flavonoids: tricetin (Campos et al, 2002;Campos et al, 1997), isorhamnetin (Lins et al, 2003;Tomas-Lorente et al, 1992), 8-methoxyherbacetin (Campos, 1997;Dauguet et al, 1993), and naringenin (Strohl and Seikel, 1965) have been isolated previously from pollen loads. This is however the first report of D-mannitol as a constituent of pollen loads with a substantial proportion (34.9%).…”

“…Há séculos o pólen das abelhas vem sendo utilizado na medicina popular para aliviar e curar constipações, gripes, úlceras, envelhecimento precoce e outros 4,5 e atualmente existem diversos trabalhos de pesquisa sobre as potencialidades e interesse terapêutico do pólen de abelhas do gênero Apis, que vão desde o tratamento de rinites alérgicas 6,7 , hepatoprotetor 8 e antiteratogênico 9,10 . Este trabalho relata o resultado obtido da investigação química do pólen coletado pela abelha sem ferrão Scaptotrigona bipunctata.Os flavonóides encontrados no pólen são geralmente glicosilados, apenas alguns trabalhos citam os flavonóides do tipo aglicona 11,12,13,14 . O presente trabalho mostra a presença de quatro flavonóides agliconas, sendo o flavonóide diidromiricetina relatado pela primeira vez em pólen de abelhas.…”
