This study investigates, the physicochemical characteristics of Sengmaksan (SM) prepared with Liriope platyphylla (LP) that had been roasted for different times (0, 30, 60, and 90 min, denoted as S-0, S-30, S-60, and S-90, respectively) The Hunter’s color values such as lightness (L), redness (a), and yellowness (b) were the highest in S-0, while the lowest was found in S-90. The amount of soluble solid and reducing sugar content of S-60 were higher than the others. None of the samples exhibit significant differences in, their pH and acidity. The total content of phenolic compounds increased with the LP roasting time, but the total flavonoid and total anthocyanin contents of the SM decreased at the same time. The total ginsenoside (Ro, Rb2, Re, Rf, Rg1, Rg2, Rg3, Rh1, and Rh2) content did not show significant differences. The DPPH and ABTS radical scavenging activities increased according to the concentration, as well as with the LP roasting time. The ferric reducing antioxidant power (FRAP) showed trends similar to the radical scavenging activity, but it was more sensitive to the LP roasting time. From these results, the active ingredient in S-60 was higher, and the antioxidant activities of SM increased along with the roasting time of LP.

A New Cymbidium variety "Yellow Evening" was developed from a cross between "Oji" and "Valley Flower Cherry Life" followed by seedling and line selections at the National Institute of Horticultural and Herbal Science (NIHHS), Rural Development Administration (RDA) in 2004. After investigation of the characteristics and selection for 9 years (1996-2004), it has been selected specifically pot orchid flower. "Yellow Evening" has medium plant height and semi-erect peduncle. It has medium flowering habit and brownish yellow flowers (RHS, Y11B: petal and sepal) with grayed purple GP183A) spot on lip, when fully opened. Each peduncle has 15.3 flowers with diameter of about 7.4 cm. It has adequate peduncle height, with some curved and spreading petal and sepals. Under optical culture conditions, it started to bloom early-winter (November).

A new Phalaenopsis hybrid “White Angel” was selected from the progenies derived from self-pollination of collection, “PN 3005 in 1995 at National Horticultural Research Institute (NHRI) Rural Development Administration. Final selection was applied in 2003 after the investigation of the characteristics for five years (1999-2003). “White Angel” has white flower with red rip and is a medium sized Phalaenopsis variety with semi-upright leaf and high PLBs (Protocorm ike bodies) formation ability of 70%. “White Angel” has white flower with red rip and is a medium sized (Flower width is 8.3 cm and leaf length is 25 cm) Phalaenopsis variety with semi-upright leaf and high PLBs (Protocorm like bodies) formation ability of 70%. Strong sunlight and over irrigation should be avoided for the appropriate growth.
