Abstract

Objectives: The chemical composition of cactus pear seed oil (Opuntia ficus-indica [L.] Mill.) was analyzed in terms of its fatty acid composition, tocopherol content, phenolic identification, and the oil's phenolic-rich fraction antioxidant power was determined.

Methods: Fatty acid profiling was performed by gas chromatography coupled to an FI detector. Tocopherols and phenolic compounds were analyzed by LC-FLD/UV, and the oil's phenolic-rich fraction antioxidant power was determined by phosphomolybdenum, DPPH assay and β-carotene bleaching test.

Results: Fatty acid composition was marked by a high unsaturation level (83.22 ± 0.34%). The predominant fatty acid was linoleic acid (66.79 ± 0.78%), followed by oleic acid (15.16 ± 0.42%) and palmitic acid (12.70 ± 0.03%). The main tocopherol was γ-tocopherol (172.59 ± 7.59 mg/kg. In addition, Tyrosol, vanillic acid, vanillin, ferulic acid, pinoresinol, and cinnamic acid were identified as phenolic compounds in the analyzed seed oil. Moreover, the oil's phenolics-rich fraction showed a significant total antioxidant activity, scavenged DPPH up to 97.85%, and effectively protected β-carotene against bleaching (97.56%).

Conclusion: The results support the potential use of cactus pear seed oil as a functional food.

仙人掌梨籽油的化学成分：酚类物质的鉴定和抗氧化活性。

目的：分析仙人掌果籽油（Opuntia ficus-indica [L] Mill：分析仙人掌果籽油（Opuntia ficus-indica [L.] Mill：方法：采用气相色谱法和荧光检测器进行脂肪酸分析。方法：采用气相色谱-荧光检测器对脂肪酸进行分析，采用 LC-FLD/UV 对生育酚和酚类化合物进行分析，采用磷钼、DPPH 法和β-胡萝卜素漂白试验测定油中富含酚类成分的抗氧化能力：脂肪酸组成的特点是不饱和度高（83.22 ± 0.34%）。最主要的脂肪酸是亚油酸（66.79 ± 0.78%），其次是油酸（15.16 ± 0.42%）和棕榈酸（12.70 ± 0.03%）。主要的生育酚是γ-生育酚（172.59 ± 7.59 毫克/千克）。此外，酪醇、香草酸、香兰素、阿魏酸、松脂醇和肉桂酸被鉴定为分析籽油中的酚类化合物。此外，油中富含酚类的部分显示出显著的总抗氧化活性，对 DPPH 的清除率高达 97.85%，并能有效保护β-胡萝卜素免受漂白（97.56%）：结果支持仙人掌果籽油作为功能性食品的潜在用途。

期刊介绍： The Journal of Pharmacopuncture covers a wide range of basic and clinical science research relevant to all aspects of the biotechnology of integrated approaches using both pharmacology and acupuncture therapeutics, including research involving pharmacology, acupuncture studies and pharmacopuncture studies. The subjects are mainly divided into three categories: pharmacology (applied phytomedicine, plant sciences, pharmacology, toxicology, medicinal plants, traditional medicines, herbal medicine, Sasang constitutional medicine, herbal formulae, foods, agricultural technologies, naturopathy, etc.), acupuncture (acupressure, electroacupuncture, laser acupuncture, moxibustion, cupping, etc.), and pharmacopuncture (aqua-acupuncture, meridian pharmacopuncture, eight-principles pharmacopuncture, animal-based pharmacopuncture, mountain ginseng pharmacopuncture, bee venom therapy, needle embedding therapy, implant therapy, etc.). Other categories include chuna treatment, veterinary acupuncture and related animal studies, alternative medicines for treating cancer and cancer-related symptoms, etc. Broader topical coverage on the effects of acupuncture, the medical plants used in traditional and alternative medicine, pharmacological action and other related modalities, such as anthroposophy, homeopathy, ayurveda, bioelectromagnetic therapy, chiropractic, neural therapy and meditation, can be considered to be within the journal’s scope if based on acupoints and meridians. Submissions of original articles, review articles, systematic reviews, case reports, brief reports, opinions, commentaries, medical lectures, letters to the editor, photo-essays, technical notes, and book reviews are encouraged. Providing free access to the full text of all current and archived articles on its website (www.journal.ac), also searchable through a Google Scholar search.
