摘要:

Monolaurin alone and monolaurin with tert‐butylhydroxyanisole (BHA), methylparaben, or sorbic acid were tested for in vitro virucidal activity against 14 human RNA and DNA enveloped viruses in cell culture. At concentrations of 1% additive in the reaction mixture for 1 h at 23°C, all viruses were reduced in infectivity by>99.9%. Monolaurin with BHA was the most effective virucidal agent in that it removed all measurable infectivity from all of the viruses tested. The compounds acted similarly on all the viruses and reduced infectivity by disintegrating the virus envelo

摘要:

LauricidinR(monolaurin) and related compounds were tested against 16 fungi belonging to different groups and having different cell wall composition. Lauricidin Plus F (a combination of monolaurin, butylated hydroxy anisole and ethylenediaminetetraacetic acid) was the most effective agent and inhibited the growth of all fungi tested at a concentration of 0.1%. Lauribic (a combination of monolaurin and sorbic acid) also exhibited strong antifungal activity but was less effective than Lauricidin Plus F. In most cases Lauricidin showed antifungal activity at a concentration of 0.5%. Other commercial samples of monolaurin, e.g. Lauricidin 812 (A), Lauricidin 802 (B), and Lauricidin 112 (C), showed higher antifungal activity than Lauricidin. Tests comparing Lauricidin Plus F with sorbic acid, K sorbate and propionic acid, showed that Lauricidin Plus F has higher antifungal activity except when sclerotia of Sclerotium rolfsii were used for inoculation. Lauricidin Plus F was fungistatic and maintained its activity in a semi‐synthetic medium for at least 21 days at 26

摘要:

Results are presented for a limited survey performed in 1978 for residues of ethylenebisdithiocarbamate (EBDC) fungicides and ethylenethiourea (ETU) in raw and canned spinach and tomato samples (12 samples each of the raw and 12 each of the canned commodities). Correlated samples of each commodity were obtained by batch sampling the canned commodity and the corresponding raw commodity. Most of the tomato sample analyses were negative for EBDC and ETU. However, the 12 raw, unwashed spinach samples contained relatively high levels of EBDC residues (5.2 — 80 ppm calculated as zineb) and 0.12 — 2.3 ppm ETU; the ETU residue levels were somewhat proportional to the EBDC residue levels. It appears that washing the spinach before canning removes the EBDC residues, but not the ETU residues. Cooking the raw spinach samples in the laboratory to yield “cooked” or “total” ETU was found to be useful for identification and semiquantitative confirmation of EBDC residues. There was considerable variation between replicate ETU determinations for each spi
