Investigation of the Biochemical and Nutrient Content of Microgreens of Some Salvia L. Species

Abstract

Objective: This study was conducted to determine some biochemical parameters and macro-nutrient contents of Salvia species. The absence of a previous study on the subject adds a unique value to this research, making it the first of its kind. Therefore, it is anticipated to contribute significantly to the literature. Materials and Methods: In this study, the potential for evaluating microphylls of Salvia hispanica L. (Chia), Salvia sclarea (Clary sage), Salvia dichroantha Stapf., Salvia officinalis L. (Common sage), Salvia microstegia Boiss. & Bal., and Salvia verticulata ssp. verticulata species was investigated. A growth medium consisting of sterilized peat, coconut coir (cocopeat), and perlite obtained from a commercial company was placed into 500 cc plastic pots, lightly pressed, and then seeds were sown. The soil was covered with a layer twice the diameter of the seed, and watering was done by spraying. The experiment was arranged in a Randomized Complete Block Design with 4 replications and placed in a fully controlled climate chamber with a 16/8 light/dark period. Results: As a result of the study, the highest total chlorophyll content (23.61 µg/g FW) was obtained from Salvia hispanica species, while the total antioxidant activity capacity (285.8 µmol TE/g), flavonoid content (16.62 mg QE/100g), and ascorbic acid amount (63.85 mg LAA/100g) were found in Salvia dichroantha Stapf. The phenolic content (210.3 mg GAE/g) was highest in Salvia sclarea species. Regarding macro-nutrients, the highest accumulation of Ca, Mg, and Na was observed in Salvia sclarea, while the highest accumulation of K was found in Salvia dichroantha Stapf. species. Conclusion: This study has revealed the potential for consumption of the investigated Salvia species as microgreens, providing an additional consumption area particularly for sage, which is rich in polyphenols.

Bazı Salvia L. Türlerine Ait Mikroyeşillerin Biyokimyasal ve Besin Elementi İçeriklerinin Araştırılması

Öz

Amaç: Bu çalışma, Salvia türlerinin bazı biyokimyasal parametreleri ile makro besin elementi içeriklerini tespit etmek amacıyla yürütülmüştür. Konu ile ilgili daha önceden yapılmış bir çalışmanın olmaması, ilk olma özelliği taşıması bu çalışmaya ayrı bir özgün değer katmaktadır. Dolayısıyla, literatüre katkı sağlayacağı öngörülmektedir. Materyal ve Yöntem: Çalışmada, materyal olarak Salvia hispanica L. (Chia), Salvia sclarea (Misk adaçayı), Salvia dichroantha Stapf. (Kutnu), Salvia officinalis L. (Tıbbi adaçayı), Salvia microstegia Boiss. & Bal. (Yağlambaç) ve Salvia verticulata ssp. verticulata (Dadırak) türlerinin mikrofiliz olarak değerlendirilme potansiyeli araştırılmıştır. Ticari bir şirketten temin edilen steril torf, hindistan cevizi kabuğu (cocopeat) ve perlit karışımından oluşan büyüme ortamı 500 cc’lik plastik şalelerin içerisine konulmuş hafif bastırıldıktan sonra tohum ekimleri yapılmıştır. Tohumların üzeri tohum çapının 2 katı olacak şekilde toprak ile kapatılmış ve spreyleme şeklinde sulama yapılmıştır. Deneme, Tesadüf Parselleri Deneme Deseni’ ne göre 4 tekrarlamalı olarak düzenlenmiş ve tam kontrollü iklim kabinine 16/8, aydınlık/ karanlık periyotta kalacak şekilde yerleştirilmiştir. Araştırma Bulguları: Çalışma sonucunda; en yüksek toplam klorofil içeriği (23.61 µg/g TA), Salvia hispanica türünden, toplam antioksidan aktivite kapasite (285.8 µmol TE/g), flavonoid madde (16.62 mg QE/100g) ve askorbik asit miktarı (63.85 mg LAA/100g) Salvia dichroantha Stapf. türünden, fenolik madde miktarı (210.3 mg GAE/ g) Salvia sclarea türünden elde edilmiştir. Makro besinler bakımından en yüksek Ca, Mg ve Na birikimi Salvia sclarea, en fazla K birikimi Salvia dichroantha Stapf. türünden elde edilmiştir. Sonuç: Bu çalışma ile incelenen Salvia türlerinin mikroyeşillik olarak tüketilebilme potansiyelleri ortaya konulmuş polifenoller bakımdan zengin içeriğe sahip olan adaçayına obsiyonel bir tüketim alanı kazandırılmıştır.
