Abstract:
A new triterpenoid saponin named esculentoside U(1), along with the five known compounds, was isolated and characterized from the roots of Phytolacca acinosa, a commonly used traditional Chinese medicine with anti-inflammatory and anti-rheumatoid activities. The structure of the new saponin was elucidated as 3-O-[β-D-glucopyranosyl-(1→4)]-β-D-xylopyranosyl]-2, 23-dihydroxyolean-11, 13(18)-diene-28, 29-dioic acid 29-methyl ester(1). The assignment of all NMR signals of 1 was performed by means of 2D-NMR experiments.

Properties of the Root Locus
To determine if a point lies on the root locus, the criterion involves the sum of angles contributed by all poles and zeros to that point. Specifically, this sum must be an odd multiple of 180 degrees. The gain at any point on...

Construction of Root Locus
For positive gain values, the root locus exists on the real axis to the left of an odd number of finite open-loop poles or zeros. The root locus starts at the open-loop poles and traces the paths of the closed-loop poles as the gain...
