Chemical constituents and free radical scavenging activity of corn pollen collected from Apis mellifera hives compared to floral corn pollen at Nan, Thailand

Table 1 The weight and the character of the three crude solvent extracts from bee pollen and corn pollen

Crude extract^a	Yield^b (g)	Yield^c (% of pollen sample)	Appearance
Corn bee pollen extracts
CMEb	35.29	8.40	Dark brown sticky solid
CDEb	2.40	0.57	Dark brown solid
CHEb	18.13	4.32	Yellow solid
Floral corn pollen extracts
CMEp	9.02	2.15	Dark brown solid
CDEp	4.82	1.15	Brown solid
CHEp	7.87	1.87	Dark green oil/wax

^aCMEb, CDEb and CHEb stand for the crude methanol, DCM and hexane extracts of the bee pollen, while CMEp, CDEp and CHEp stand for the crude methanol, DCM and hexane extracts of the floral corn pollen.
^b,cThe yield of each crude extract as ^bthe net weight (g) and ^cthe proportion (% (w/w)) of the total starting pollen mass.
