Phytochemistry Letters, 2017 Two new hemiterpene glycosides, named as securiterpenoside B (1), and securiterpenoside C (2), and one new phenolic glycoside, named as securiphenoside A (3) were isolated from the roots of Securidaca inappendiculata Hassk. Their structures were elucidated on the basis of 1D and 2D NMR data and HRESIMS and comparisons with published data.

Hepatoprotective hemiterpene glycosides from the rhizome of Cibotium barometz (L.) J. Sm
Phytochemistry, 2017 Five previously undescribed hemiterpene glycosides, cibotiumbarosides E-I, and two known hemiterpene glucosides, were isolated from the rhizome of Cibotium barometz (L.) J. Sm. The structures of cibotiumbarosides E-I were established by 1D and 2D NMR spectroscopic analyses and HRMS.

Two new hemiterpene glycosides from the leaves of Ilex rotunda. thunb
Archives of Pharmacal Research, 2012 Chromatographic separation of the 80% MeOH extract of the leaves of Ilex rotunda (IR) led to isolation of two new hemiterpene glycosides, tentatively named as rotundarpenoside A (1) and rotundarpenoside B (2), along with five known caffeoyl derivatives (3-7).

Bacterial Degradation of tert-Amyl Alcohol Proceeds via Hemiterpene 2-Methyl-3-Buten-2-ol by Employing the Tertiary Alcohol Desaturase Function of the Rieske Nonheme Mononuclear Iron Oxygenase MdpJ [PDF]
Journal of Bacteriology, 2011 Tertiary alcohols, such as tert-butyl alcohol (TBA) and tert-amyl alcohol (TAA) and higher homologues, are only slowly degraded microbially. The conversion of TBA seems to proceed via hydroxylation to 2-methylpropan-1,2-diol, which is further oxidized to 2-hydroxyisobutyric acid. By analogy, a branched pathway is expected for the degradation of TAA, as
