Table 1.

Ratios of (R)- to (S)-1PE in the endogenous 1PE in different floral organs.

Floral Organs	(R)-1PE	(S)-1PE
Filaments	97.2 ± 0.3 a	2.8 ± 0.3 a
Anthers	92.6 ± 0.1 bc	7.4 ± 0.1 bc
Petals	90.1 ± 1.8 c	9.9 ± 1.8 c
Receptacles	86.0 ± 1.9 d	14.0 ± 1.9 d

The data are expressed as mean ± S.D. (n = 3). Three groups of floral organs were used for analysis. Each group contained floral organs from a mixture of 15 tea flowers. Different mean ± S.D. with different letters in the same column are significantly different from each other (p ≤0.05).
