From the commercial extract of the leaves of Stevia rebaudiana, a new diterpene glycoside was isolated besides the known steviol glycosides including stevioside, rebaudiosides A-F, rubusoside and dulcoside A. The new compound was identified as 13-[(2-O-β-D-glucopyranosyl-3-O-β-D-glucopyranosyl-β-D-glucopyranosyl)oxy] ent-kaur-16-en-19-oic acid-(2-O-α-L-rhamnopyranosyl-β-D-glucopyranosyl) ester (1) on the basis of extensive spectroscopic (NMR and MS) and chemical studies.
从甜叶菊（Stevia rebaudiana）的商业提取物中，除了已知的甜菊糖苷（包括甜菊苷、莱鲍迪苷 A-F、毛蕊花糖苷和杜尔可苷 A）外，还分离到一种新的二萜糖苷。该新化合物通过广泛的光谱（NMR 和 MS）和化学研究，被鉴定为 13-[(2-O-β-D-吡喃葡萄糖基-3-O-β-D-吡喃葡萄糖基-β-D-吡喃葡萄糖基)氧基] -ent-贝壳杉-16-烯-19-酸-(2-O-α-L-鼠李吡喃糖基-β-D-吡喃葡萄糖基)酯（1）。
