One of the habitats for ferns in the upper reaches of the river in Bengkulu is the Pasmah River. The Pasmah River is a source of water for the people of Bengkulu and its surroundings. To maximize the role of the river, it is necessary to make an inventory of plants around the river, one of which is ferns. This study aims to determine the diversity of types and variations of pteridophyta sorus. A sampling of ferns was carried out on the banks of the Pasmah River, Central Bengkulu. Purposive sampling was used in this study to pinpoint the location, and the cruising (cruise method) was used to collect sample data. The results showed that there were 15 types of ferns where 12 types of ferns were found with sorus, 6 types of ferns were round, 4 were elongated, 1 was in line, 1 was strobili and 3 species had no sorus.

Tuber extracts. The content of secondary metabolites is determined by using phytochemical tests, and toxicity tests are carried out by the Brine Shrimp Lethality Test (BSLT) method. Hydnophytum bulbs from Jukung Village, Lubuklinggau City, South Sumatra were macerated using 96% ethanol and then evaporated until thick extracts were obtained. This thick extract was then tested for secondary metabolite content, fractionated using n-hexane, and ethyl acetate. The results of the fractionation were then carried out a toxicity test using the BSLT method. Secondary metabolite test results showed ethanol extract containing flavonoids, alkaloids, tannins, saponins, terpenoids, and phenolics. The result of fractionation was obtained by the tuber extract of Hydnophytum n-hexane fraction, ethyl acetate fraction, and ethanol fraction. Toxicity test results obtained LC50 values of n-hexane fraction of 52.3 ppm, LC50 of ethyl acetate fraction of 45.9 ppm, and LC50 of ethanol fraction of 99 ppm. All Hydnophytum tuber extract fractions were categorized as toxic and have potential as anti-bacterial or anti-oxidant. The fraction that has the lowest LC50 price is the most toxic fraction. The most toxic fraction is the most active fraction. The ethyl acetate fraction was the most active fraction because it has the lowest LC50.
