“…The high proportions of →4)-GalpA-(1→, →3,4)-GalpA-(1→ and Xylp-(1→ (Table 2), together with our earlier NMR analyses (Alba et al, 2020), was consistent with the presence of mostly (~ 62 %) xylogalacturonan (Figure 1A). Patova et al, (Patova et al, 2021) showed that baobab fruit xylogalacturonan had a low degree of methylesterification (~20 %) and our NMR data was consistent, also showing a similarly low proportion of the carboxyl groups of the →4)-GalpA-(1→ being methyl esterified (Alba et al, 2020). A small proportion of the carboxyl groups of the →4)-…”

“…4(b)). The fractions with lower Mw and high percentage of GalA (more than 70 mol%) were assembled into the same subgroup, which could consist of homogalacturonan (HG) regions in pectic polysaccharides possibly substituted with neutral monomers, such as T‐Xyl p 42 or T‐Rha p , as reported in AL‐I‐II 24 . T‐Fuc p could be the terminal sugar of AG side chains 41 …”

BackgroundAconitum carmichaelii is an industrially cultivated medicinal plant in China and its lateral and mother roots are used in Traditional Chinese Medicine due to the presence of alkaloids. However, the rootlets and aerial parts are discarded after collection of the roots, and the non‐toxic polysaccharides in this plant were less concerned than the alkaloids and poisonous features. In this study, five neutral and 14 acidic polysaccharide fractions were systematically isolated from different plant parts of A. carmichaelii, and their structural features and bioactivities were studied and compared.ResultsThe neutral fraction isolated from the rootlets was different from those isolated from the lateral and mother roots, consisting of less starch and more possible mannans, galactans, and/or xyloglucans, which was similar to those of the aerial parts. Pectic polysaccharides containing homogalacturonan and branched type‐I rhamnogalacturonan (RG‐I) were present in all plant parts of A. carmichaelii. However, more arabinogalactan (AG)‐II side chains in the RG‐I backbone were present in the aerial parts, while more arabinans followed by AG‐I/II were found in the roots. Various immunomodulatory effects determined by complement fixation activity and anti‐inflammatory effects on intestinal epithelial cells IPEC‐J2 of all polysaccharide fractions were observed.ConclusionThis study highlighted the diversity of polysaccharides present in A. carmichaelii, especially in the unutilized plant parts, and showed their potential medicinal values.This article is protected by copyright.

“…1,2,4‐linked Rha p was detected in ASP−I−I, which means that neutral side chains could be attached to O ‐4 of Rha p , such as arabinans (composed of terminal, 1,5‐ and 1,3,5‐linked Ara f ), type II arabinogalactans (AG‐II) (consisting of 1,3‐ and 1,3,6‐Gal p ), or minor amounts of β‐1,4‐galactans (1,4‐linked Gal p ) [33] . Branches at O ‐3 of GalA (1,3,4‐linked Gal p A) might be due to terminal Xyl p or methyl‐ or acetyl‐esterification [34] . The HG region in ASP−I−II seems to be longer than in ASP−I−I as it contains around 15 mol % more of 1,4‐linked Gal p A (Table 2), and more terminal Xyl p moieties could be attached to O ‐3 of Gal p A.…”

Aconitum septentrionale is known to contain toxic diterpene alkaloids, while other bioactive compounds in the plant remain unclear. The aim of this study was to explore the phenolic compounds and polysaccharides from the water extract of A. septentrionale roots. Fifteen phenolic compounds were isolated and identified by NMR and MS, including fourteen known and one new dianthramide glucoside (2‐[[2‐(β‐D‐glucopyranosyloxy)‐5‐hydroxybenzoyl]amino]‐4,5‐dihydroxybenzoic acid methyl ester, 14). One neutral (complex of glucans with minor amounts of mannans) and two acidic polysaccharide fractions (complexes of pectic polysaccharides and glucans) were also obtained. Hydroxytyrosol (1), hydroxytyrosol‐1‐O‐β‐glucoside (2) and bracteanolide A (7) inhibited the release of nitric oxide by dendritic cells. Magnoflorine (8) and 2‐[[2‐(β‐D‐glucopyranosyloxy)‐5‐hydroxybenzoyl]amino]‐5‐hydroxybenzoic acid methyl ester (12) inhibited 15‐lipoxygenase, and bracteanolide A (7) was a moderate inhibitor of xanthine oxidase. This study is the first to describe the diversity of phenolics and polysaccharides from A. septentrionale and their anti‐inflammatory and anti‐oxidant activities.
