Abstract

Epidemiological evidence indicates that plant antioxidants activity can treat or help to prevent the development of various diseases. One species with great potential as an antioxidant is Curcuma longa. However, different extraction techniques can influence isolated chemical compounds. This study investigated chemical composition and antioxidant activity of two rhizome extracts of C. longa: hydroethanolic, obtained by exhaustion (HECLex); and dried by a spray dryer (HECLsd). The phytochemical composition was evaluated by GC/MS. Antioxidant activity was evaluated using DPPH and FRAP assays. Total phenolic compounds and soil analyses were performed. The main components of HECLex were ar-turmerone, γ-curcumene, α-turmerone, and β-sesquiphellandrene. The main components of HECLsd were 9,12,15-octadecatrienoic acid, 2,3-bis([trimethylsilyl]oxy)propyl ester, verrucarol, and 1-monolinoleoylglycerol trimethylsilyl ether. HECLsd had significantly higher levels of phenolic compounds and higher antioxidant capacity compared with HECLex. In conclusion, processes of the preparation of C. longa rhizomes alter the chemical components and consequently their biological activity.

不同制备工艺对姜黄素和姜黄素组成及抗氧化作用的影响

流行病学证据表明，植物抗氧化剂活性可以治疗或帮助预防各种疾病的发展。姜黄是一种极具抗氧化潜力的植物。然而，不同的提取技术会影响分离的化合物。本文研究了龙骨根两种提取物的化学成分和抗氧化活性:氢乙醇;用喷雾干燥机(HECLsd)干燥。采用气相色谱/质谱法测定其植物化学成分。采用DPPH和FRAP测定抗氧化活性。进行了总酚类化合物和土壤分析。HECLex的主要成分为ar-姜黄酮、γ-姜黄烯、α-姜黄酮和β-倍半黄烯。HECLsd的主要成分为9,12,15-十八碳三烯酸、2,3-二([三甲基硅基]氧)丙酯、疣芦醇和1-单油酸油基甘油三甲基硅基醚。与HECLex相比，HECLsd具有更高的酚类化合物水平和抗氧化能力。综上所述，龙骨根的制备过程改变了其化学成分，从而改变了其生物活性。

期刊介绍： The Boletín Latinoamericano y del Caribe de Plantas Medicinales y Aromáticas (BLACPMA), [Latin American and Caribbean Bulletin of Medicinal and Aromatic Plants]; currently edited by the publishing house MS-Editions, is a bi-monthly international publication that publishes original peerreviewed research in the field of medicinal and aromatic plants, with nearly 20 years of experience. BLACPMA is a scientific journal that publishes two types of articles: Reviews (only in English) and Original Articles (Spanish or English), its main lines of action being agronomy, anthropology and ethnobotany, industrial applications, botany, quality and standardization, ecology and biodiversity, pharmacology, phytochemistry, pharmacognosy, regulatory and legislative aspects. While all areas of medicinal plants are welcome and the experimental approaches used can be broad and interdisciplinary; other areas of research that are not mentioned depend on the Editorial Committee for their acceptance.
