Research on stingless bee products has increased in recent years, and of particular interest is propolis because of its biological activities such as antioxidant and antimicrobial.However, there is paucity of information regarding intra-hive variations in the biochemical composition and biofunctional properties of this propolis.In this study, we investigated galaxy n54 the phytochemicals and radical scavenging activity (RSA) of Meliponula ferruginea propolis from 10 wooden hives (n = 49).

The samples were collected from five different locations comprising the entrance, involucrum, pillars, pots and sealant.Principal component analysis showed that there is an intra-hive variation in phytochemical content and RSA.Phenolic content constituted the highest phytochemical content in all the locations.

The sealant and entrance had the highest amounts of phytochemicals compared to the involucrum, pillars and pots.Further analysis of propolis extracts by gas chromatography-mass spectrometry revealed occurrence of different compounds such as monoterpenoids, hydrocarbons, triterpenoids and alkaloids.Hydrocarbons were common in all parts while monoterpenes and triterpenes were present in the entrance.

The findings of our study indicates that there is an intra-hive variation in 2010 chevy malibu exhaust manifold propolis of M.ferruginea and hence this information will provide further insight into better understanding of stingless bee propolis.
