Sterols and triterpenoids as potential anti-inflammatories: Molecular docking studies for binding to some enzymes involved in inflammatory pathways

Cebulak

et al. 2018

The activity of polyphenolic compounds, triterpenoids, carotenoids, chlorophylls and antioxidants in leaves and rhizomes of Fallopia japonica Houtt and Fallopia sachalinensis (F.Schmidt) grown in Poland was investigated. Leaves and rhizomes were assessed for the presence of bioactive compounds with the ultra-performance liquid chromatography photodiode detector-quadrupole/time-of-flight mass spectrometry (UPLC-PDA-Q/TOF-MS) method, and for antioxidant activity with the on-line UPLC-ABTS screening. Forty-six polyphenolic compounds (15 phenolic acids, 12 flavones and flavonols, 11 flavan-3-ols and 8 stilbenes), were identified in Fallopia japonica and Fallopia sachalinensis. Furthermore, accurate mass measurement technique was for the first time in Fallopia japonica Houtt and Fallopia sachalinensis (F.Schmidt) in leaves and rhizomes it identified 25 new compounds belonging to carotenoids (9), chlorophylls (13) and triterpenoids (3) as well as rated the antioxidant properties of each polyphenolic compound. Major qualitative differences were found in the profiles. The leaves and rhizomes were found to be a good source not only of (average 20408.18 and 2716.42 mg/100 g dm), but also chlorophylls (average 179.97 and 43.82 mg/100 g dm), carotenoids (average 100.23 and 53.25 mg/100 g dm) and triterpenoids (average 580.87 and 434.05 mg/100 g dm). The content of bioactive compounds in Fallopia japonica Houtt was around 8.0, 4.0, 2.0 and 1.3 times higher than the content of polyphenols, chlorophylls, carotenoids and triterpenoids in Fallopia sachalinensis (F.Schmidt). The accurate identification of Fallopia bioactive compounds is an indispensable detailed knowledge of the profile and step toward better understanding of the medicinal properties of the species and also potentially more extensive use of the plant.

“…Triterpenoids exhibit many biological activities such as antifungal, antibacterial, antiviral, antiprotozoal, and anti-inflammatory [4]. Triterpenoids-derivatives of triterpenes such as oleanolic, ursolic, or betulinic acids-are mainly located in cuticular waxes [8].…”

Determination of triterpenoids, carotenoids, chlorophylls, and antioxidant capacity in Allium ursinum L. at different times of harvesting and anatomical parts

2018

Triterpenoids, carotenoids, chlorophylls, and antioxidant capacity of individual parts of wild garlic at different times of harvesting were studied. Leaves, flowers, bulbs, and stems of Allium ursinum were used in this study. The contents of triterpenoids, carotenoids, and chlorophylls were determined by UPLC-PDA-Q/TOF-MS, and the antioxidant capacity was determined by ABTS and FRAP assay. A total of 21 compounds including 3 triterpenoids, 11 carotenoids, and 7 chlorophylls were identified in anatomical parts of A. ursinum in March and June 2016. These compounds present in individual anatomical parts of wild garlic were determination in this study for the first time ever. The average content of total triterpenoids ranged from 750.7 to 4159.5 mg/kg dry matter (dm) and that of carotenoids and chlorophylls ranged from 14.4 to 14,424.5 mg/kg dm for bulbs and leaves. The average level of the antioxidant capacity ranged from 37.1 to 91.7 µmol Trolox/g dm in bulbs and leaves, respectively. The leaves, flowers, and stems of wild garlic are a good source of health-promoting compounds. They can be used as functional food ingredients, dietary supplements, and additives.

“…They are widespread in the world of plants and are the subject of numerous phytochemical and pharmacological studies. Plants with high levels of triterpenes are often used in phytotherapy because of their valuable anticancer, antioxidative, anti-inflammatory, antibacterial, antifungal, and antiprotozoal properties [11][12][13].…”
