F. Their structures were elucidated by spectroscopic methods. The mixture of scyphiphin B 1 and scyphiphin B2 showed moderate cytotoxicity against human hepatoma SMMC-7721 cell line in vitro by MTT method.展开更多

Metro Manila was once a part of a tropical mangrove forest dominatedby small trees locally called nilad (Scyphiphora hydrophyllaceae). The fast-paced urbanization transformedthe original ecosystem into a bustling metropolis subjected to environmental decay. The establishment ofurban forestry is one of the interventions sought by the government to mitigate the environmental conditions.Thus, the concept of participatory urban forestry was formalized in 1988 by the national government.However, it was during the early years of the 1970s that the idea of exerting collective effort in greeningMetro Manila started through the Green Revolution, with the primary motive of uplifting the economiccondition of the people rather than on ecological enhancement. The project was forced on the people to plantvegetables and fruit trees with less emphasis on forest trees species. Although the project was not successful,the government realized that the citizenry could be a great partner for a collective worthwhile undertaking.展开更多
