Abstract

The present invention is concerned with extracts of Asteraceae containing reduced levels of phototoxic thiophene derivatives. Novel methods that may result in about a fifty-fold to hundred-fold or more reduction of phototoxic thiophene levels in a commercially attractive process is described. The Asteraceae plant extracts comprising xanthophylls with reduced levels of thiophene derivatives may be used in applications that include nutritional supplements and cosmetics.

Claims (11)

1. A valve comprising:

a closure member including a longitudinal channel;

a first valve stem operably coupled to the closure member to effect movement of the closure member via movement of the first valve stem, the first valve stem including a first channel in communication with the longitudinal channel, the first valve stem including a first opening in communication with the first channel;

a first piston operably coupled to the first valve stem, such that movement of the first valve stem effects movement of the first piston, the first piston located between the first opening and the closure member;

a second valve stem operably coupled to the closure member to effect movement of the second valve stem via movement of the closure member, the second valve stem including a second channel in communication with the longitudinal channel, the second valve stem including a second opening in communication with the second channel; and a second piston operably coupled to the second valve stem, such that movement of the second valve stem effects movement of the second piston; the second piston located between the first opening and the closure member.
2. The valve of claim 1, wherein the closure member further includes a latitudinal channel in communication with the longitudinal channel.
3. The valve of claim 1, further comprising a valve body.
4. The valve of claim 3, further comprising a first bonnet operably coupled to the valve body, the first bonnet positioned, located, and configured to position the first valve stem.
5. The valve of claim 4, further comprising a first sleeve operably coupled to the first bonnet, an interior of the valve body, and the first piston, the first sleeve operable to allow movement of the first piston.
6. The valve of claim 5, wherein the first piston is configured to isolate a portion of an interior of the first sleeve from a remainder of the interior of the valve body.
7. The valve of claim 4, wherein the first piston is configured to isolate a portion of the first bonnet from a remainder of an interior of the valve body.
8. The valve of claim 4, further comprising a second bonnet operably coupled to the valve body, the second bonnet positioned, located, and configured to position the second valve stem.
9. The valve of claim 3, where in the second piston is configured to isolate a portion of an inner cavity of the valve body.
10. The valve of claim 1, further comprising a first plug stem operably coupling the first valve stem to the closure member, the first plug stem having another channel in communication with the longitudinal channel and the first channel.
11. The valve of claim 1, wherein at least one of the first valve stem and the second valve stem is configured for attachment to a valve actuator.
