“…Olive pulp (OP) is the remainder of olive cake (raw material resulting from olive oil extraction) after the cake is dried. It is also one of the most interesting by-products of olive tree farming, being a good source of several biologically active compounds with antioxidant, antifungal, and antibacterial properties [1][2][3][4][5] with a great nutraceutical potential [6][7][8][9][10][11][12][13][14]. The use of by-products from different vegetal origins to supplement feed is, on the other hand, attracting growing interest due to environmentally friendly use, efficacy, and sustainability, other than avoiding the necessity to dump potentially useful and valuable by-products of the agro food system [15,16].…”

Nowadays, there is an increasing interest in the exploitation and valorization of agricultural food waste and by-products. At the same time, the growing demand by markets worldwide, especially in Africa and Southeast Asia, can justify the growing interest in the use of by-products for the poultry industry. Olive pulp is one of the most interesting by-products of olive tree farming (typical of the Mediterranean area), being a good source of many biologically active compounds with antioxidant, antifungal, and antibacterial properties. The presence of processed olive pulp in the diet showed to be effective in increasing the weight of specific carcass and offal traits. This work aims at studying olive pulp as a feed supplement in poultry nutrition, by focusing on the effects on broiler carcass and offal. Olive pulp (OP) is one of the by-products of olive tree farming, being the residue of olive cake after it is dried. To evaluate the effects of OP in a diet supplemented with different levels of a commercial enzyme (ENZ) blend on broiler carcass and offal traits, three hundred male broiler chicks (Ross 308 lineage; one-day-old) were divided into ten treatment groups according to a completely randomized design. The treatments diets contained: unprocessed OP (50 g/kg, 100 g/kg, 50 g/kg with ENZ, 100 g/kg with ENZ), processed OP (50 g/kg, 100 g/kg, 50 g/kg with ENZ, 100 g/kg with ENZ), and control groups (without OP, and without OP with ENZ). The OP processing increased breast percentages in broilers. Supplementation with ENZ did not change any of the studied carcass or offal trait values. The presence of OP (50 g/kg) in broiler diets increased the eviscerated carcass, leg, and neck percentage values. The presence of processed OP (50 g/kg) in the diet showed to be effective in increasing the weight of specific carcass and offal traits.

The roots of Dipsacus asper Wall as a commonly used traditional Chinese medicine are used for tonifying liver and kidney and strengthening bones and muscles. However, an effective separation strategy for comprehensive and rapid separation of the main active compounds from the roots of D. asper is nonexistent. This investigation provided an effective separation method based on AB-8 macroporous resin column chromatography using different ratios of ethanol in water and two different modes of high-speed countercurrent chromatography with salt-containing solvent system for rapid enrichment and separation from the roots of D. asper. The macroporous resin column chromatography was performed on AB-8 resin using ethanol in water ratios of 10, 30, 40, 50, and 80% as the optimized enrichment conditions for iridoid glycosides and triterpenoid saponins with different polarities. For high-speed countercurrent chromatography separation, the conventional and recycling modes were combined together to develop a strategy for 12 compounds (1-12) from the enriched parts of 30, 40, and 80% ethanol, including six high-polarity iridoid glycosides (1-6) using inorganic salt-containing solvent system and six triterpenoid saponins (7-12). Recycling high-speed countercurrent chromatography separation was successfully applied to separate two isomers (9 and 10) after 11 cycles.

“…Huang et al [21] developed a continuous CCC method based on the elution‐extrusion mode, and successfully applied the method for the separation of maslinic acid (MA) and oleanolic acid (OA) from olive pulp extract for the first time. In this study, they chose a n ‐hexane/ethyl acetate/methanol/water solvent system with a wide polarity range and high stationary phase retention.…”

Elution‐extrusion counter current chromatography extrudes the most solute retained in the column with the highest possible peak resolution. It can greatly improve the hydrophobic window. In recent years, elution‐extrusion counter current chromatography has received extensive attention in the separation of complex samples. This article first reviews the development and application of elution‐extrusion counter current chromatography, including its origin, mechanism, advantages and disadvantages, and some representative applications. At the same time, this review also shared our visions and ideas on how to improve the elution‐extrusion mode. This article aims to provide certain reference for the research of this technology.
