Clerodane glycosides and flavonoids in Dicranopteris pedata and three varieties of D. linearis were investigated. All the ferns contained a new glycoside, (6S,13S)-6-[6-O-acetyl-beta-D-glucopyranosyl-(1-->4)-alpha-L-rhamnopy - ranosyloxy]-13-[alpha-L-rhamnopyranosyl-(1-->4)-beta-D-fucopyra nosyloxy]- cleroda-3,14-diene, as a chemical marker of this group. Flavonoids were limited to flavonol 3-O-glycosides. The ferns and isolated flavonoids are as follows; D. pedata: afzelin, quercitrin. D. linearis var. brevis: afzelin, quercitrin. D. linearis var. tenuis: quercitrin, isoquercitrin. D. linearis var. sebastiana: astragarin, isoquercitrin, rutin, kaempferol 3-O-(4-O-p-coumaroyl-3-O-alpha-L-rhamnopyranosyl)-alpha-L-rhamn opy ranosyl- (1-->6)-beta-D-glucopyranoside.
对芒萁和线蕨三个变种中的克罗烷苷和黄酮类化合物进行了研究。所有蕨类植物都含有一种新的糖苷，(6S,13S)-6-[6-O-乙酰基-β-D-吡喃葡萄糖基-(1→4)-α-L-鼠李吡喃糖氧基]-13-[α-L-鼠李吡喃糖基-(1→4)-β-D-岩藻吡喃糖氧基]-克罗烷-3,14-二烯，作为该类群的化学标志物。黄酮类化合物仅限于黄酮醇3-O-糖苷。这些蕨类植物和分离出的黄酮类化合物如下：芒萁：阿夫泽林、槲皮苷。线蕨变种短叶线蕨：阿夫泽林、槲皮苷。线蕨变种细叶线蕨：槲皮苷、异槲皮苷。线蕨变种赛巴斯蒂安线蕨：紫云英苷、异槲皮苷、芦丁、山柰酚3-O-(4-O-对香豆酰基-3-O-α-L-鼠李吡喃糖基)-α-L-鼠李吡喃糖基-(1→6)-β-D-吡喃葡萄糖苷。
