“…The amounts of β-sitosterol in the leaf powders of HP cultivars corresponded to the quantitative pattern of ursolic acid, with the greatest amounts in ‘Avgustinka’ and ‘Voroblevskaja’ (373.81 ± 12.65 µg/g and 283.84 ± 9.54 µg/g, respectively) ( Table 2 ). Kukin et al, 2017 [ 27 ], determined β-sitosterol as the predominant compound in the profile of triterpenoids and sterols. The leaf powders of cultivar ‘Julia’ were distinguished by the greatest ( p < 0.05) amounts of corosolic acid—263.05 ± 8.82 µg/g.…”

“…Due to the specific attachments of fruits, the branches are pruned during harvesting. As the leaves are also a very promising raw material, no-waste technologies could be promoted [ 27 ]. The leaves contain similar phytochemical profiles as fruits, but have significantly higher amounts of phenolic compounds, especially hydrolysable and condensed tannins, triterpenic compounds, and flavonoids [ 10 , 19 , 20 , 21 ].…”

Sea Buckthorn Leaf Powders: The Impact of Cultivar and Drying Mode on Antioxidant, Phytochemical, and Chromatic Profile of Valuable Resource

et al. 2021

Sea buckthorn (Hippophae rhamnoides L. (HR)) leaf powders are the underutilized, promising resource of valuable compounds. Genotype and processing methods are key factors in the preparation of homogenous, stable, and quantified ingredients. The aim of this study was to evaluate the phenolic, triterpenic, antioxidant profiles, carotenoid and chlorophyll content, and chromatic characteristics of convection-dried and freeze-dried HR leaf powders obtained from ten different female cultivars, namely ‘Avgustinka’, ‘Botaniceskaja Liubitelskaja’, ‘Botaniceskaja’, ‘Hibrid Percika’, ‘Julia’, ‘Nivelena’, ‘Otradnaja’, ‘Podarok Sadu’, ‘Trofimovskaja’, and ‘Vorobjovskaja’. The chromatic characteristics were determined using the CIELAB scale. The phytochemical profiles were determined using HPLC-PDA (high performance liquid chromatography with photodiode array detector) analysis; spectrophotometric assays and antioxidant activities were investigated using ABTS (2,2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) and FRAP (ferric ion reducing antioxidant power) assays. The sea buckthorn leaf powders had a yellowish-green appearance. The drying mode had a significant impact on the total antioxidant activity, chlorophyll content, and chromatic characteristics of the samples; the freeze-dried samples were superior in antioxidant activity, chlorophyll, carotenoid content, and chromatic profile, compared to convection-dried leaf powder samples. The determined triterpenic and phenolic profiles strongly depend on the cultivar, and the drying technique had no impact on qualitative and quantitative composition. Catechin, epigallocatechin, procyanidin B3, ursolic acid, α-amyrin, and β-sitosterol could be used as quantitative markers in the phenolic and triterpenic profiles. The cultivars ‘Avgustinka’, ‘Nivelena’, and ‘Botaniceskaja’ were superior to other tested cultivars, with the phytochemical composition and antioxidant activity.

“…In sea buckthorn, carotenoids are not only the main components that contribute to the color of sea buckthorn but are also health-promoting compounds [4,5]. Carotenoids contribute to prevent or ameliorate chronic diseases in the body, such as cancer, cardiovascular disease and skin and eye diseases [6][7][8]. However, sea buckthorn juice has a mixed and unstable system due to its fatty acids content and fine pulp particles, resulting in unfavorable phase separation in the product.…”

The need to improve the physicochemical properties of sea buckthorn juice and the bioavailability of carotenoids is a major challenge for the field. The effects of different natural emulsifiers, such as medium-chain triglycerides (MCTs), tea saponins (TSs) and rhamnolipids (Rha), on the physical and chemical indexes of sea buckthorn juice were studied. The particle size of sea buckthorn juice and the carotenoids content were used as indicators for evaluation. The effects of different addition levels of MCT, Rha and TS on the bioavailability of carotenoids in sea buckthorn juice were investigated by simulating human in vitro digestion tests. The results showed that those emulsifiers, MCT, Rha and TS, can significantly reduce the particle size and particle size distribution of sea buckthorn juice, improve the color, increase the soluble solids content, turbidity and physical stability and protect the carotenoids from degradation. When the addition amount of Rha was 1.5%, the total carotenoids content (TCC) of sea buckthorn juice increased by 45.20%; when the addition amount of TS was 1.5%, the total carotenoids content (TCC) of sea buckthorn juice increased by 37.95%. Furthermore, the bioaccessibility of carotenoids was increased from 36.90 ± 2.57% to 54.23 ± 4.17% and 61.51 ± 4.65% through in vitro digestion by Rha and TS addition, respectively. However, the total carotenoids content (TCC) of sea buckthorn juice and bioaccessibility were not significantly different with the addition of MCT. In conclusion, the findings of this study demonstrate the potential of natural emulsifiers, such as MCT, Rha and TS, to significantly enhance the physicochemical properties and bioavailability of carotenoids in sea buckthorn juice, offering promising opportunities for the development of functional beverages with improved nutritional benefits.

“…Sea buckthorn branches are pruned when picking berries due to the specific attachment of fruits. Since the leaves, bark, shoots and woody part of sea buckthorn are also very promising raw materials, it is necessary to promote waste-free technologies [7]. In this regard, the issues of finding rational ways to isolate valuable components from the non-fruit part of sea buckthorn and obtaining an additional amount of valuable substances are undoubtedly relevant today [8].…”

Intensification of water extraction of non-fruit parts of sea buckthorn (Hippóphaë rhamnóides)

The healing properties of extracts from sea buckthorn fruits have been confirmed by numerous studies, however, the infertile parts remaining after harvesting or after pruning young trees also contain valuable components. Leaves, bark, shoots and woody parts of sea buckthorn are very promising raw materials for the extraction of biologically active substances. The introduction of non-waste technologies, issues of resource conservation, the search for rational ways to isolate valuable components from the non-fruit part of sea buckthorn determined the relevance of this study. The choice of the optimal method for the extraction of non-fruit parts of sea buckthorn is aimed at accelerating heat and mass transfer processes and increasing the rate of diffusion extraction of biologically active substances. The paper reflects the results of experimental studies of traditional aqueous extraction of non-fruit parts of sea buckthorn, namely leaves, bark, shoots and wood, and the results of intensification of extraction by preliminary freezing of the feedstock. The influence of the raw material freezing rate on the size of the formed ice crystals is analyzed. It has been established that at a freezing rate of 0.1-1 cm/ h, large ice crystals form in the intercellular space of plant raw materials, causing mechanical damage to cellular structures and contributing to better leaching of biologically active substances, which is confirmed by experimental studies.
