- Observation Eight labdane diterpenoids and one sesquiterpene were isolated from N. glutinosa.
- Observation Three named diterpenoids were identified from tobacco for the first time.
- Observation Labdane diterpenoids were most abundant in flowers and upper-middle leaves at 1260–1457 μg/g FW.
- Observation Sclareol accounted for 50% of total labdane diterpenoids.
- Observation N. glutinosa crude extract and fractions Fr.3/Fr.4 inhibited TMV, gray mold, and apple valsa canker.
- Observation Sclareol inactivated TMV at 66.37% at 200 μg/mL.
- Observation Labdenediol inactivated TMV at 55.28% at 200 μg/mL.
- Observation Sclareol, 2α/2β-hydroxymanool, and labdenediol inhibited Botrytis cinerea growth by 72.37–80.20% in vitro at 20 μg/mL.
- Observation Sclareol, 2α/2β-hydroxymanool, and labdenediol inhibited Botrytis cinerea growth by 68.14–83.60% in vivo at 100 μg/mL.
- Observation 13-epimanoyl oxide inhibited Valsa mali growth by 94.60%, similar to carbendazim.
- Association Anti-TMV activity may correlate with C−8 hydroxylation.
- Mechanism Antifungal activity depended on amphiphilic balance between the parent nucleus and polar groups.
