Neutral lipids, phospholipids, and biological activity of extracts from Zygophyllum oxianum

摘要

The chemical composition of lipid extracts from aerial parts of Zygophyllum oxianum was determined by GC and TLC. The yield of total lipids was 0.75% in leaves, 0.33% in stems, and 0.49% in fruit calculated for fresh plant mass. Phospholipids were represented by nine classes, of which phosphatidylcholine dominated (55.8% in leaves, 56.4% in stems, 63.7% in fruit of total PL). The n-BuOH extract from the plant aerial part exhibited noticeable antifungal activity. The CHCl _3:MeOH (2:1) extract from leaves and stems exhibited pronounced in vitro cytotoxicity against human bladder carcinoma cell line 5637 with IC _(50) 6.2 μg/mL.
