Structures of the novel diterpene glycosides from Stevia rebaudiana

Carbohydrate Research, 2011
From the commercial extract of the leaves of Stevia rebaudiana, two new diterpenoid glycosides were isolated besides the known steviol glycosides including stevioside, rebaudiosides A-F, rubusoside, and dulcoside A. The structures of the two new compounds were identified as 13-[(2-O-6-deoxy-β-d-glucopyranosyl-β-d-glucopyranosyl)oxy] ent-kaur-16-en-19 ...

Minor Diterpene Glycosides from the Leaves of Stevia rebaudiana

Journal of Natural Products, 2014
Two new diterpene glycosides in addition to five known glycosides have been isolated from a commercial extract of the leaves of Stevia rebaudiana. Compound 1 (rebaudioside KA) was shown to be 13-[(O-β-d-glucopyranosyl)oxy]ent-kaur-16-en-19-oic acid 2-O-β-d-glucopyranosyl-β-d-glucopyranosyl ester and compound 2, 12-α-[(2-O-β-d-glucopyranosyl-β-d ...

Amarisolide, a neo-clerodane diterpene glycoside from Salvia amarissima

Phytochemistry, 1996
A new neo-clerodane glycoside, amarisolide, has been isolated from the aerial parts of Salvia amarissima. Its structure was established as 2β-O-β-D-glucopyranosyl neo-cleroda-3,13(16),14-trien-15,16-epoxy-18,19-olide by chemical and spectroscopic means.
