Fourteen terpenoids, including six new compounds, have been isolated from the marinespongeAcanthellacavernosa collected off Hachijo-jima Island. They inhibit of larval attachment and metamorphosis of the barnacle Balanus amphitrite. Their structures were determined mainly by spectroscopic methods.

sesquiterpenoids of the skeletal types caryophyllane, cadinane, oplopane, eudesmane, allo-aromadendrane and 4-epi-guaiane, were isolated from Pulicaria paludosa. Their structures were established mainly by NMR techniques and chemical transformations. Four of them are new natural products. Three flavonoids and some simple phenolic derivatives were also isolated.
investigation of Pittosporum glabratum var. neriifolium EtOH extract led to four aromadendrane sesquiterpenoid glycosides, including one new, pitglabroside A (1), together with eight other kinds of constituents (5-12). Their structures were elucidated by comprehensive spectroscopic analysis, including 1D and 2D NMR, HRESIMS and ECD spectra. Four sesquiterpenoid glycosides (1-4) were evaluated for their inhibitory
A composition including a plurality of particles, wherein the particles include: about 30% to about 95% by weight of a carrier; about 0.1% to about 30% by weight of a perfume; and about 0.00025% to about 30% by weight of a malodor agent; wherein the malodor agent comprises one or more malodor reduction materials having a Blocker Index of less than 3 or a Blocker Index average of 3 to about 0.001; and wherein each of the particles has a mass between about 0.1 mg to about 5 g.

The present invention relates to hair care compositions comprising malodor reduction compositions and methods of using such hair care compositions. Such hair care compositions comprising the malodor control technologies disclosed herein provide malodor control without leaving an undesirable scent and when perfume is used to scent such compositions, such scent is not unduly altered by the malodor control technology.
