  • Encapsulated structure for plant initiate material
    Patent number: 5250082
    Abstract: Disclosed is an encapsulated structure for plant initiate material. Plant initiate material is encapsulated in a waterproof membrane coating or waterproof capsule, onto which water swellable polymeric material particles are partly embedded. This structure provides the encapsulated plant initate material with sufficient pressure resistance to endure rough handling, and allows the plant initiate material to gerninate without difficulty since during imbibition the water swellable particles would swell after absorbing water and thus break the waterproof memebrane coating or the waterproof capsule.

  • Process for the isolation of antifungal agents (5-methoxy-7-hydroxyflavan) from dragon's blood resin and its use in agriculture
    Patent number: 5063244
    Abstract: 5-methoxy-7-hydroxyflavan compound (I) was isolated and purified from Dragon's Blood resin. The purification process involves 50% ethanol soxhletion overnight and then fraction through silica column with a series of solvent elution. The purified compound (I) was crystallized in benzene: hexane (1:1). The pure compound was identified by instruments including IR, NMR, FAB-MS, and GC-MS and acetylation reaction to confirm the structure. This compound was found to be a strong antifungal chemical with broad spectra against Fusarium oxysporium fsp. niveum, Phytophora capsici, Phoma asparagi, Pythium spinosum, Pythium aphanidermatum, Phthium sylvaticum, Sclerotium rolfsii, and Sclerotinia sclerotiorum . For whole plant in vivo testes, it was found that compound (I) significantly protected mung bean and cabbage from being infested and damaged by Sclerotium rolfsii and Pythium aphanidermatum respectively.
