The invention provides a method for quickly adding different types of compounds to an electronic experimental notebook. The method comprises the following steps of inputting the different types of the compounds needed to be recorded in a writing region or a description region, identifying the compounds and obtaining compound related data; performing addition according to compound information, and performing matching with a compound database firstly during the addition: when the matching succeeds, automatically adding the compounds to a display unit and performing display in a display region; when the matching fails, in response to selective addition, adding the compounds to the display unit in a user-defined manner and performing display in the display region; and obtaining a list of the compound information added to the display region, and adding the list to an operation unit. Through the step of quickly adding the different types of the compounds to the electronic experimental notebook, the supported compounds can be quickly added and obtained; the types of the compound information can be automatically obtained; and the different types of the added compounds can be subjected to type adjustment.
