**2.2 Aporphines and benzylisoquinolines, and furoquinolines**

Aporphines and benzylisoquinolines, and furoquinolines (**52**–**75**) were reported from *Zanthoxylum* species. Magnoflorine (**52**), lauriforine (**55**), skimmianine (**69**), *γ*-fagarine (**70**), and dictamnine (**71**) were found in *Zanthoxylum* species such as *Z. americanum*, *Z. bouetense*, *Z. budrunga*, *Z. caribaeum*, *Z. clava-herculis*, *Z. cuspidatum*, *Z. dimoncillo*, *Z. fagara*, *Z. monophyllum*, *Z. nitidum*, *Z. ovalifolium*, *Z. rubescens*, *Z. schinifolium*, *Z. simulans*, *Z. usambarense*, and *Z. williamsii* (**Figure 3** and **Table 2**)*.*

#### **2.3 Quinolines, quinolones, and quinazolines**

There were 19 quinolines, quinolones, and quinazolines (**79**–**97**) isolated from *Zanthoxylum* species. They are mainly found in *Z. simulans* and *Z. nitidum* (**Figure 4** and **Table 3**)*.*

#### **2.4 Indolopyridoquinazolines, acridones, and canthinones**

There are 10 indolopyridoquinazolines, acridones, and canthinones (**98**–**107**) isolated from *Zanthoxylum* plants (*Z. atchoum*, *Z. simulans*, and *Z. ovalfolium*).
