[Effect of fertilization combinations of nitrogen, phosphorus, and potassium on four phenolic compounds of cultivated Rhodiola crenulata].

This study is aimed to explore the effect of nitrogen, phosphorus and potassium combined application on the active components of Rhodiola crenulata. R. crenulata was used as the research object, "3414" fertilization experiment were conducted with regular fertilization of NPK(N 60 kg·hm⁻², P₂O₅ 100 kg·hm⁻²,KCl 160 kg·hm⁻²) to study the effect of different rates of NPK fertilization on the total amount of 4 phenolic constituents of gallic acid, salidroside, tyrol and ethyl gallate through field test.

Ensuring equitable benefits: the falealupo covenant and the isolation of anti-viral drug prostratin from a samoan medicinal plant.

Equitable sharing of benefits from pharmacological development of biodiversity has been the topic of much discussion, but few concrete examples of recent plant-derived pharmaceuticals exist. The discovery of prostratin as an anti-viral phorbol isolated from healer preparations of the rain forest tree Homalanthus nutans in Samoa illustrates the importance of careful liaison between western scientists and indigenous leaders. Development of prostratin as an anti-AIDS drug candidate was based on a carefully negotiated covenant between the chiefs and orators of Falealupo village and western researchers, with the concurrence of the Samoan Prime Minister and members of parliament.
