A flavonoid compound in flavonol type namely kaemferol was isolated from the ethyl acetate fraction of the methanol extract of the fern Chingia sakayensis (Zeiller) Holtt's leaves. The DPPH free radical scavenger activity of kaemferol was stronger than buthyl hyroxy toluene (BHT) but it was weaker than ascorbic acid (vitamin C) and -tocopherol (vitamin E). Keywords: Chingia sakayensis, kaemferol, DPPH free radical scavenger activity

The larvicidal potential of extracts from Myxopyrum Serratulum was evaluated against larvae of Aedes aegypti. The results from the present study showed that the petroleum ether and methanolic extract from M. Serratulum exhibited significant toxic effects against Ae. aegypti larvae with LC50 value of 134.2 μg/ml and 172.47 μg/ml, respectively. Two compounds myxopyroside (1) and kaemferol (2) were isolated from methanolic extract. However, the synergetic effect of Kaemferol with Phenolic compound of methanolic extract shows higher larvicidal activity than petroleum ether extract.

Shallots can be used to compress, this is because onions contain organic sulfur compounds, namely allycysteine ??sulfoxide (aliin) which functions to destroy blood clots. Other ingredients of shallots that can lower body temperature are phlorogusin, cycloaliin, methylaliin, and kaemferol. The purpose of this study was the effect of compressing shallots (allin essential oil) on reducing fever in children under five in Hasik Jaya Village, Moswaren District, South Sorong Regency.
