RESULTS AND DISCUSSION
Volatile Constituents of the Extracts. The yields of
volatile chemicals were 0.36 ± 0.03% and 0.25 ± 0.03% from
Mulberry leaves and stems, respectively, 0.15 ± 0.02% and 0.24
± 0.03% from of Camellia green and fermented teas,
respectively, and 0.15 ± 0.02% and 0.24 ± 0.03% from Burea
plant stems and roots, respectively. Table 1 shows the volatile
constituents identified in the present study in the extracts from
Mulberry tea (leaves and stems), Camellia tea (green and
fermented), and Burea plant (stems and roots) along with their
Kovats index. A total of 101 compounds were positively
identified. In addition, 24 chemicals are listed as tentatively
identified because authentic samples were not available; of
these, however, over 90% matched with the MS library in the
NIST AMDIS version 2.1 software. The chemicals that were
found by DB-WAX but not by DB-1were also listed as
tentatively identified
