Table 4: Cont. The \(\beta\)-sitosterol share, among confirmed phytosterols, varied from 22% (coriander seed oil from plants grown in India) [74] to 95% (cucumber seed oil from plants grown in Thailand) [209]. In contrast, campesterol was the predominant compound in coriander seed oil from plants grown in India (78%) [74]. Stigmasted was a significant compound of phytosterols only in purple carrot [131] (34% of the total fraction). Bearing in mind these three main phytosterols in total share, the most variable were oils from blackcurrant, blueberry, fenugreek, onion, and tomato seeds. For these oils, the sum of \(\beta\)-sitosterol, campesterol, and stigmasted was often above 80% of the total fraction (specific and more detailed data in the cited references). The problem when comparing sterol content was giving different names for the same compound (for example, \(\Delta\)5-avenasterol = isofucosterol). To facilitate results comparison, both commonly used names for most phytosterols are used in Table 4.  
Considering the EPSA recommendation on phytosterol use in doses of 1.3 g of sterols or 3.5 g of stands, approximately 2-3 tablespoons of Japanese quince oil may meet this recommendation.
