The first chemotaxonomic study based on volatile components of <i>Porella viridissima</i> (Mitt.) Grolle is reported. The GC-MS analysis of ether extract was performed; ten santalane and five pinguisane-type sesquiterpenes were identified together with perrottetianal A as major diterpene. Most of detected santalane-type sesquiterpenes are reported for the first time in liverwort. <i>P. viridissima</i> was found to belong to the chemotype III (pinguisane/sacculatane) and shared chemical similarities with <i>P. navicularis</i>. Perrotettianal A was isolated and has shown strong cytotoxicity against ovarian cancer.

Cytotoxic bibenzyls, and germacrane- and pinguisane-type sesquiterpenoids from Indonesian, Tahitian and Japanese liverworts2011 •
Cytotoxic bibenzyls, and germacrane- and pinguisane-type sesquiterpenoids have been isolated from unidentified Indonesian and Tahitian Frullania sp. and Japanese Porella perrottetiana by using a combination of chromatographic methods. The structure activity relationship (SAR) study showed that the presence of a phthalide group in bibenzyls, an alpha-methylene-gamma-lactone in germacrane-type sesquiterpenoids, and beta-hydroxycarbonyl in pinguisane-type sesquiterpenoids play an important role in providing cytotoxic activity against both human promyelocytic leukemia (HL-60) and human pharyngeal squamous carcinoma (KB) cell lines. The structure of each isolated compound was elucidated by using spectroscopic methods and the cytotoxicity was determined by using the WST-8 colorimetric assay.

Volatile Components of Selected Liverworts, and Cytotoxic, Radical Scavenging and Antimicrobial Activities of Their Crude Extracts2010 •
Crude extracts of the Tahitian liverworts Mastigophora Diclados and Frullania sp., the Indonesian Frullania sp., Dumortiera hirsuta and Marchantia sp., and the Japanese Porella perrottetiana were investigated chemically by using gas chromatography-mass spectrometry (GC-MS). All extracts contained various volatile sesqui- and diterpenoids and a few aromatic compounds. The Tahitian M. diclados and Frullania sp., and the Indonesian Frullania sp. exhibited cytotoxic activity against HL-60 and KB cell lines. The extracts of the Tahitian M. diclados and the Indonesian Marchantia sp. showed radical scavenging activity, whereas the crude extracts of the Tahitian M. diclados and Frullania sp., and the Indonesian Frullania and Marchantia sp. showed antimicrobial activity against Staphylococcus aureus and Bacillus subtilis.
