A new pregnane steroid, jasminanthoside (), together with three known compounds, telosmoside A7 (), syringaresinol (), and methyl 6-deoxy-3--methyl--D-allopyranosyl-(1→4)--D-oleandropyranoside () were isolated from the ethyl acetate extract of roots collected in Vietnam. Their chemical structures were elucidated by NMR and MS spectroscopic data analysis along with the comparison of their data with the published ones in the literature. Although was a known compound, its full NMR data were reported for the first time.

An intensely sweet polyoxypregnane glycoside, telosmoside A15 (15), was isolated from an Asian Asclepiadaceae plant, Telosma procumbens, collected in Vietnam. This is the first time a sweet pregnane glycoside has been found, and its sweetness intensity is 1000 times greater than that of sucrose. From the same plant, 17 other new glycosides were isolated, having the same aglycone; they are named telosmosides A1-A14 (1-14) and A16-A18 (16-18).
