Pure, food grade sunflower lecithin is widely available here in the U.S., I'm assuming it's not so easy to acquire in Nigeria and that's why you are asking. You didn't mention whether you needed a special grade and I have not seen lab grade sunflower lecithin. Try this source: http://www.pipingrock.com/sunflower-lecithin/sunflower-lecithin-powder-non-gmo-40317. They are one of the few companies that mentions international shipping on their website. I hope that helps.

Lecithin is easy extracted as phosphatidyl cholein and some modification if agree let me know and send to you and help you in all thinks
