<p>Seabuckthorn plants (<em>Hippophae Linn</em>), belonging to the family Elaeagnaceae have shown diverse therapeutic potential and the adaptogenic activity of some of the species have also been established in our previous studies. The present study aims to characterize aqueous and alcoholic leaf extracts of three different varieties of seabuckthorn, namely, <em>Hippophae salicifolia</em>, <em>Hippophae rhamnoides mongolica </em>and <em>Hippophae rhamnoides turkestanica</em> and evaluate their antioxidant potential <em>in vitro. </em>An elaborate characterization of phytochemicals such as volatile organic compounds (VOC) and flavonoids occurring in the concerned extracts has been carried out by GC-MS and HPTLC respectively. GC-MS demonstrated the presence of 35 distinct VOCs in the seabuckthorn leaf extracts which are known to possess substantial pharmacological and antioxidant potential. The most abundant VOCs identified were trimethylsilyl palmitate, methyl octadec-9-enoate, methyl palmitate, methyl stearate and methyl (9E)-9-octadecenoate. HPTLC results revealed variable quantities of quercetin, gallic acid, ascorbic acid and rutin in all the seabuckthorn leaf extracts. HPTLC-centered chemometric analysis using R programming helped to distinguish among the various extracts based on pattern recognition and unsupervised clustering, thus, enabling grouping of the extracts for further studies.</p>

Hippophae rhamnoides L. is an important source of natural antioxidant and antimicrobial agents. Phytochemical compounds, antioxidant and antibacterial properties of berries, and leaf extracts from four Romanian sea buckthorn cultivars were investigated. Large differences in the content of total polyphenols and flavonoids between the varieties were observed. HPLC analysis of the polyphenolic compounds showed greater differences in content in leaves than in berries. This study confirmed that sea buckthorn leaves and berries are a rich source of phenolic compounds, especially quercetin derivatives and hydrocinnamic acid derivatives. Five carotenoid compounds were identified in the berries: lutein, zeaxanthin, β-cryptoxanthin, cis-β-carotene, and β-carotene. From the results obtained in this study, it can be stated that the varieties whose berries yielded the highest quantities of polyphenols, flavonoids, and antioxidant activity, can be ranked as follows: SF6 > Golden Abundant > Carmen > Colosal, and for leaf extracts the ranked order is SF6 > Golden Abundant > Colosal > Carmen. A strong correlation between the total flavonoid yield and antioxidant activity (r = 0.96), was observed. All extracts showed antibacterial activity against S. aureus, B. cereus, and P. aeruginosa, however extracts from berries were less potent than extracts from leaves.

Summary Introduction: Antioxidants, isolated from different plant parts, are widely used due to their ability to prevent the development of so-called oxidative stress. Sea buckthorn (Hippophae rhamnoides L.) is one of the plants with expected antioxidant properties. Objective: The aim of the study was to evaluate the antioxidant activity of ethanolic, methanolic and acetonic extracts of H. rhamnoides leaves, ripe and unripe fruits obtained by ultrasound-assisted extraction. Methods: To estimate the antioxidant potential of the extracts the DPPH, FRAP, ABTS and Folin-Ciocalteu methods were applied. Moreover, the influence of the extrahent, as well as extraction time, on this activity was evaluated. Results: Sea buckthorn leaf extracts showed higher activity, contrary to the fruit extracts. Moreover, higher activity of ripe fruit extracts compared to unripe material extracts was found. To obtain the highest content of antioxidants in the extracts, ultrasound-assisted extraction for 60 min with methanol should be applied. Conclusions: The presented in vitro results could lead to the conclusion that H. rhamnoides seems to be a valuable source of antioxidants to be applied in various branches of industry.
