Extract

Seno laiku civilizācijas kā ēģiptieši, grieķi un ķīnieši ieguva daudzas noderīgas ķimiskas vielas no augiem un dzīvniekiem.
Tā laika cilvēki pazina cukuru, kuru pielietoja vīna pagatavošanai.
No pagatavotā vīna tika iegūts etiķis.
Zilo krāsu Senajā ēģiptē ieguva no augu saknēm, bet purpura no retas molusku sugas.
Ziepes tika gatavotas sildot dzīvnieku taukus un sajaucot tos ar pelniem. Tāpat no augiem tika iegūtas arī dažādas ārstnieciskās vielas.
