“…Therefore, its stability is more than that of the un-encapsulated extract. These results are in line with the previous reports of Han et al [32], Tang et al [33], and Jeon et al [34]. The stability of protease encapsulated into CNPs was evaluated by Tang et al [33] and they showed that the stability of protease encapsulated into CNPs increased when exposed to temperature and pH.…”

“…The stability of protease encapsulated into CNPs was evaluated by Tang et al [33] and they showed that the stability of protease encapsulated into CNPs increased when exposed to temperature and pH. Additionally, Han et al [32] encapsulated the extract of jujube seeds and pulp into CNPs and evaluated the stability of the extract via antioxidant assays. They revealed that the antioxidant activity of the extract encapsulated into CNPs did not change significantly after 12 days, while the antioxidant capacity of the un-encapsulated extract decreased significantly.…”

Physalis alkekengi-L is a medicinal herb with a high antioxidant capacity. It is used to treat various diseases. In this study, encapsulation of the hydro-alcoholic extract of P. alkekengi-L into chitosan nanoparticles (CNPs) was optimized by using response surface methodology, and its antioxidant capacity and anticancer activity were investigated. The results of the antioxidant capacity evaluation showed that the antioxidant activity of the chitosan nanoparticles containing extract did not significantly decrease by increasing the time of storage (over a 12 day period) as compared to that of un-encapsulated extracts. In conclusion, CNPs can be used to encapsulate and improve the stability of P. alkekengi-L extract and its antioxidant properties.

“…jujuba (Ziziphus jujuba; Miller) might be useful as a natural functional food ingredient with antioxidant activity and phenolic content. It is used as flavoring agent and additive because of the high nutrient content [21,35,54]. jujuba has considerable amount of ascorbic acid and contains compounds such as glycoside, sterol, alkaloid, tannin, saponin, organic acids, amino acids, triterpenoid, flavonoid, carbohydrate and minerals including potassium, iron, calcium, phosphorus and vitamins including A, B and C [32,41,56].…”

Influence of carboxy methyl cellulose (CMC) and pectin on rheological, physical stability and sensory properties of milk and concentrated jujuba mixture

As a functional component, jujuba concentrate can be added to foods with the aim of promoting nutritional value. This study was done to evaluate the rheological, physical stability and sensory properties of milk-jujuba concentrate (MJC) mixture. The rheological properties of MJC mixture affected by different concentrations of pectin and carboxy methyl cellulose (CMC) were investigated by rheometer and zetasizer. According to the results, the best rheological model to describe flow behavior of the samples was ''power law'' with the predominant behavior in most samples being Newtonian and some samples pseudo plastic. Treatment containing pectin-CMC and 2 % jujuba concentrate showed significantly higher qualitative properties (p \ 0.01). Viscosity increased as the amount of concentrate and hydrocolloid increased. Stabilized samples showed decreased f-potential compared to the control (without hydrocolloid).

“…Among them there is the possibility to provide drug sustained release in a way to decrease side effect and decrease dosage. Ziziphus jujuba fruits have a low shelf-life due to the fast oxidation of its phenolic compounds (Han et al, 2015). In this way, the encapsulation of previously optimized hydroethanolic extract (40-100% ethanol) in chitosan nanoparticles increased the stability of the phenolic compounds in respect to free extract (DPPH antioxidant activity).…”

In many cases, from a pharmacological point of view, it is interesting to work with crude extract or fractions instead of a single isolated compound. This could be due to multi-targeting effect of the extract, lack of knowledge of the active compounds, synergistic effect of the extract compounds, among others. In any case, in order to achieve a final product some issues must be overcome, including poor stability, solvent toxicity, and low solubility of the bioactive compound. Recently many nanotechnology-based strategies have been proposed as an alternative to solve these problems, especially liposomes, nanoemulsions and nanoparticles. In this sense, the present work aims to review the main nanotechnological approaches used for association of different plant extracts and the main achievements form using these technologies.
