Based on the results of the phytochemical screening, in red betle leaf extract contained several classes of compounds such as saponins, polyphenols, quinones, tannins, steroids, monoterpenoid, sesquiterpenoids
, and flavonoids.
caryophyllene (c18), viridiflorol (c24) and spathulenol (c22), together with the non-identified compounds NI6 (c25) and NI5 (c17), provided a small contribution to PC 1 and 2 (see Figure 1).
Malvaceae: The first sesquiterpenoids
discovered to be nematotoxic were the aldehydes hemigossypol and 6-methoxyhemigossypol, in addition the dimmers gossypol, and 6-methoxygossypol.
Our results demonstrate that monoterpenoids (linalool) as well as sesquiterpenoids
([beta]-caryophyllene) may serve as an antifeedant against herbivorous insects.
Biologically active sesquiterpenoid
metabolites from the fungus Botrytis cinerea.
A novel eremophilane sesquiterpenoid
produced by a Xylaria sp.
At least eight different sesquiterpenoid
compounds including sesquiterpene aldehydes (Paul et al.
The active ingredient in gyrinidal is a sesquiterpenoid
aldehyde (Miller et al.
nigra) were tested for the presence of alkaloid, steroid/triterpenoid, saponin, polifenol, tanin, flavonoid, kuinon, monoterpenoid, and sesquiterpenoid
In contrast, the sesquiterpenoid
(-)-germacrene-D is present in the leaf and trunk volatiles of the host of M.
Known terpenoids from lichens are all shared with higher plants or marine organisms, including monoterpenoid (-)-carvone 45, sesquiterpenoid
bakkenolide A/fukinanolide A 46 from Cetraria islandica (Solberg 1986), triterpenoids [alpha]-amyrin 47, friedelan-3[beta]-ol/epifriedelinol 48, lupeol 49 and ursolic acid 50 from Flavocetraria nivalis (Bruun 1969) and zeorin 51 in the Vulpicida genus (Randlane et al.
