(L.) Hovenkamp & S. Linds is an extensively used species in traditional medicinal systems in several areas of the world due to some important medicinal properties such as antioxidant, antibacterial, analgesic, and anti-inflammatory activities. In East Timor, different parts of this fern are used either as remedies or as food. The ingestion of a broth made from its rhizome improves lactation, and young fronds of this fern are boiled and eaten with rice by the locals. Nevertheless, its chemical profile is far from being established. The present work aims to establish the chemical profile of both rhizomes and leaves -hexane extracts by Gas Chromatography- Mass Spectrometry (GC-MS). The results showed the leaves richness in fatty acids with interesting nutritional values (ω-6/ω-3 = 0.68, AI = 0.59, TI = 0.30), being linolenic acid (253.71 ± 0.93 mg/g dry leaves) and palmitic acid (237.27 ± 0.59 mg/g dry leaves) the significant compounds in the extract. Whereas the rhizome extract is mostly rich in terpenoids, such as steroid, cycloartane, and hopanoid derivatives, being hop-16-ene (166.45 ± 0.53 mg/g dry rhizome) and β-sitosterol (50.76 ± 0.11 mg/g dry rhizome) the major compounds. Several compounds are reported for the first time in the species, and the data herein reported contributes to confirming the species nutritional value.
(L.)霍文坎普蕨和林氏蕨是世界上几个地区传统医学系统中广泛使用的物种，因其具有抗氧化、抗菌、止痛和抗炎等一些重要药用特性。在东帝汶，这种蕨类植物的不同部位被用作药物或食物。食用由其根茎制成的汤可促进乳汁分泌，当地人会将这种蕨类植物的嫩蕨叶煮熟后与米饭一起食用。然而，其化学组成远未明确。本研究旨在通过气相色谱 - 质谱联用仪（GC-MS）确定根茎和叶片己烷提取物的化学组成。结果表明，叶片富含具有有趣营养价值的脂肪酸（ω-6/ω-3 = 0.68，AI = 0.59，TI = 0.30），提取物中的主要化合物是亚麻酸（253.71±0.93毫克/克干叶）和棕榈酸（237.27±0.59毫克/克干叶）。而根茎提取物主要富含萜类化合物，如类固醇、环阿尔廷烷和藿烷类衍生物，主要化合物是藿-16-烯（166.45±0.53毫克/克干根茎）和β-谷甾醇（50.76±0.11毫克/克干根茎）。该物种中首次报道了几种化合物，本文报道的数据有助于证实该物种的营养价值。
