isoboldine/inflammation

BACKGROUND Isoboldine is one of the major bioactive constituents in the total alkaloids from Radix Linderae (TARL) which could effectively alleviate inflammation and joints destruction in mouse collagen-induced arthritis. To better understand its pharmacological activities, we need to determine its

Four new sesquiterpenes (1-4), one new alkaloid (5), and one new benzenoid glycoside (6) were characterized from Lindera aggregata, and their structures were elucidated according to their spectrometric analytical data. Among these isolates, 3 and 4 were constructed as possessing unprecedented carbon

A phytochemical investigation on the roots and stems of Litsea cubeba led to the isolation of seven isoquinolone alkaloids. By spectroscopic analysis and comparison of their 1H and 13C-NMR data with those in literatures, these alkaloids were identified as (+)-norboldine (1), (+)-boldine (2),

The yellow hornpoppy, Glaucium flavum Cr. (Fam. Papaveraceae) is a perennial herb, distributed in the Mediterranean region, including Egypt. The plant contains many benzyl isoquinoline alkaloids from the aporphine type such as glaucine, isoboldine, 1-chelidonine, 1-norchelidonine and
