摘要

今后,有必要发现无毒性或副作用较小的自然资源,以取代合成药物。因此,识别、分离、测量和揭示自然资源结构中物质的生物活性至关重要。本研究考察了从植物(木槿)和昆虫(白头翁)中制备的两种提取物。使用气相色谱-质谱法(GC-MS)对释放的物质进行了取样。此外,还测定了衍生化样品的活力、凋亡和氧化应激。由于不同样品的生物学特性不同,在气相色谱-质谱分析中观察到的化学结构也不尽相同。据观察,石榴样品中含有豆甾醇及其衍生物,而胭脂虫样品中含有更多的萘酚及其衍生物。石榴花结构中含有大量的豆甾醇,细胞活力随着豆甾醇浓度的增加而增加。然而,胭脂虫样品中的细胞活力则有所下降。两种样品的细胞凋亡和氧化应激测试结果也不尽相同。因此,本研究提出了一种可用作抗病毒和抗癌剂的天然新来源。

Investigation of Sterol structures and biological activities in Cochineal and Hibiscus sabdariffa extracts
In the future, it is necessary to discover natural resources with no or less toxicity and side effects instead of synthetic drugs. Therefore, it is crucial to recognize, isolate, measure, and reveal the biological activities of substances in the structure of natural resources. In this study, the two extracts prepared from the plant (Hibiscus sabdariffa) and the insect (Dactylopius coccus) were examined. Sampling of the released substances was performed using Gas-Chromatography-Mass Spectrometry (GC-MS). In addition, viability, apoptosis, and oxidative stress of the derivatized samples were determined. Due to the biological differences between the samples, the chemical structures observed in the GC-MS analysis were not the same. It was observed that stigmasterol and its derivatives were found in the pomegranate sample, whereas naphthol and its derivatives were more abundant in the Cochineal insect sample. The cell viability increased with increasing concentrations of stigmasterol, which is present in large amounts in the structure of the pomegranate flower. However, the cell viability decreased with the Cochineal insect sample. Apoptosis and oxidative stress test results were also found to be different and contrasted for both samples. Therefore, the present study presents a new, natural, and different source that can be used as an antiviral and anticancer agent.
