“…The M w of 809.12 g mol À1 for TS was similar to the literature value [23]. In the hydrolysate of TS, L-rhamnose, D-galactose, D-glucose, and D-glucuronic acid were determined, in accordance with the literature reports [24,25]. Glucose (55.98%) accounted the main part of the glycosides in TS, followed by glucuronic acid (9.73%), rhamnose (7.25%), and galactose (0.65%) in the percentage of weight.…”

“…The potential uses of this biosurfactant were suggested by studying its surface properties, including the surface tension, critical micelle concentration, foaming performance, and its synergistic interaction with different types of synthetic surfactants. Surfactants derived from tea seed cake have been reported by several literatures, but these researches focused on the structure and the functional activities [23,24,37]. On the other hand, the researches involving mixed surfactant systems generally based on synthetic surfactants [17,[38][39][40].…”

“…In addition, the bands in the vicinity of 1100 cm À1 were assigned to the weak antisymmetric (1131 cm À1 ) and symmetric (1053 cm À1 ) stretching of C-O-C linkage as a glycosidic bond, a bond attaching monosaccharide. The FT-IR absorbance bands of TS compare well with the glycosyl and triterpene structures [23][24][25].…”

“…The extract is mainly composed of flavonoid, saponin, polysaccharide, and cellulose in accord with the references Du et al 2011). Natural flavonoids and saponins generally exist in the form of glycosides, and different kinds of glycosides of flavonoid and saponin have been found in seeds of C. oleifera (Murakami et al 2000;Gao et al 2011). Flavonoid glycosides and saponin glycosides are soluble in water and other aqueous solvents.…”

The Camellia oleifera oil industry is the economic mainstay in many highpoverty mountain regions of China, but the defatted seeds are currently discarded, leading to a waste of bioresources. In this work, a costeffective technique was designed to isolate the flavonoid, saponins, and polysaccharides by ultrasonic-assisted acid-base alternative extraction. The activities of these compounds were evaluated by their DPPH and ABTS radical scavenging abilities in vitro and inflammatory inhibition in mice, and the economic efficiency was assessed. The optimal extraction conditions by response surface design were 1.6% HCl, water/seed ratio 16, extraction time 89 min, and ultrasonic power 310 W. The yields of the flavonoid, saponin, and polysaccharide were, respectively, 1.4 ± 0.2%, 6.7 ± 0.8%, and 22.5 ± 1.7%. The extracts could eliminate DPPH and ABTS radicals and alleviate inflammation with concentration dependence, and showed excellent capacity in the order of flavonoid ≥ saponin > polysaccharides. The residue after extraction was cellulose, with a yield of 63.0 ± 2.4%. The defatted seeds could produce a value of $11.35 per kilogram after production of the four valuable extracts, which would greatly increase the income in these high-poverty areas. This integrated extraction technique provides valuable recycling utilization of a typically discarded bioresource.

“…Four times more seed cake will be produced than tea oil. The defatted seed of Camellia oleifera is a substantial byproduct that is normally used as animal feed, organic fertilizer, or detergent due to its rich concentrations of polyphenols, saponins, proteins, and polysaccharides [14]. Although some studies have examined the antioxidant properties of Camellia oil, there are few reports on the efficiency of seed cake extract of Camellia oleifera in inhibiting corn oil peroxidation.…”

The defatted seed of Camellia oleifera Abel is an underexploited byproduct. In the present study, 3 solvents (isopropanol, hexane, and diethyl ether) were used to extract active compounds from defatted seeds of Camellia oleifera Abel. The qualitative and quantitative characterization of the main phenolic compounds were performed using the HPLC-DAD. In addition, the antioxidant efficacy of defatted seed extracts in the stabilization of the corn oil was estimated by monitoring its primary and secondary oxidation products. The results showed that isopropanolic extract (IE) exhibited the highest yield of total phenolic compounds (9.23 ± 0.33 mg/g) compared with other solvents. The predominant phenolic compounds identified by HPLC-DAD in defatted seed extracts were epicatechin, naringenin, and catechin. In addition, IE exhibited the best inhibition effect on both primary and secondary oxidation products. The results reveal that IE of defatted seed of Camellia oleifera Abel is a useful antioxidant for the stabilization of corn oil.
