I'm not familiar with the word: 'alkolides' but supposedly the questioneer was looking for 'alkoxides' or 'alkaloids', so here is the answer to them.
An alkoxide is the conjugate base of an alcohol and therefore consists of an organic group bonded to a negatively charged oxygen atom. They can be written as RO−, where R is the organic substituent. Alkoxides are strong bases.
Alkaloids are a group of naturally occurring chemical compounds that contain mostly basic nitrogen atoms. This group also includes some related compounds with neutral and even weakly acidic properties. Most of them are toxic and some are used as medical drug.
Examples are caffeine, theobromine, cyclopamine, strychnine.
