from the tropical marine algae spatoglossum schmitti and Spatoglossum howleii (Dictyolaceae).
paniculata and is a natural diterpenoid
According to their chemical composition, this section is structured into three subdivisions: diterpenoid
, triterpenoid and not (exclusively) terpenoid-based resins.

lactones, sesquiterpenoid, glycosides, polysaccharides, and aliphatic compounds.
Andrographolide ([C.sub.20][H.sub.30][O.sub.5], Figure 1), a labdane diterpenoid
that is produced by Andrographis paniculata plant, has been reported to have several pharmacological properties, including antibacterial, antiviral, and antiplatelet properties, stimulation of cell differentiation, protection of the liver, being a cholagogue, antitumor properties, and immunoregulation .

Members of the family Poaceae produce mainly diterpenoid
 Stevioside, an abundant component of Stevia rebaudiana leaves, is a hydrophilic diterpenoid
glycoside with relatively high molecular weight; therefore, it is unlikely to be absorbed in the intestine unless with the help of bacterial intestinal.
