  • Patent number: 7374784
    Abstract: In a method for the production of tablets from plant extracts such as St. John's wort extract with an extract content of 80%, the extract treated on a conveyor dryer is compacted after adding 1% of silicon dioxide, and a granulate with a defined particle size distribution and therefore a defined surface area is produced from the compactate. To achieve a high rate of decomposition and active agent release with a low adjuvant content and high extract content, a combination of blasting agents including sodium hydrogencarbonate and two other, lower-dosed blasting agents such as croscarmellose sodium and sodium carboxymethyl starch—among other adjuvants—is added. The method results in a tablet suitable for oral administration containing 900 mg of St. John's wort extract.

  • Patent number: 6680072
    Abstract: A dry extract is reduced in volume by compacting to produce a solid form of pharmaceutical such as a tablet or capsule containing plant extracts. The particles of compacted matter are subsequently screened to a uniform grain size, masked with titanium dioxide, talc, and highly dispersed silicon dioxide in a first mixing process, and treated with additional adjuvants in two more mixing steps. The masked compacted matter has the flowability required for making tablets and is protected against moisture absorption. The extract portion is a minimum of 65 percent by weight, which allows for producing relatively small tablets that have low disintegration times due to masking.
