Abstract:
A new lignan, 4,4'-dihydroxy-3,3'-dimethoxy-6,9'-cycloligna-7,8'-dien-9'-al, was isolated from the stem of Syringa pinnatifolia Hems1. var. alashanensis MA. et S.Q. Zhou (S. pinnatifolia). This is the first report on the structure elucidation of a new compound based on spectroscopic methods including UV, IR, ESI-MS, 1D NMR and 2D NMR techniques.

Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
