Cinnamic Acid in Frankincense Sap as a Criterion for Determining the Best Mother Plant for Vegetative Propagation of Styrax benzoin (Sumatra Benzoin) in Sumatra, Indonesia

Table 3

Quantity of frankincense sap produced and composition of cinnamic acid in the sap of selected Styrax benzoin trees.

No.	Identity of tree	Production of sap (kg/year)	Quality of sap	Cinnamic acid (n = 3)

2	SBN-3	2.70	Super (Sidungkapi)	17.63 ± 2.93	18
3	SBN-4	2.60	Super (Sidungkapi)	14.61 ± 2.87	15
4	SBN-6	2.65	Super (Sidungkapi)	13.42 ± 2.36	13
5	SBN-7	2.70	Super (Sidungkapi)	20.70 ± 2.11	21
6	SBN-10	2.60	Super (Sidungkapi)	17.47 ± 1.53	17
Mean value		2.66 ± 0.05	Super quality	16.01 ± 2.31	16

Production of sap from tapping per tree (kg/year) in each harvest period. Quality category of frankincense sap is assessed based on the crystal size, shape, color, texture, and the selling price in traditional markets in North Sumatra Indonesia. Content of cinnamic acid (mg) contained in a gram of frankincense sap.
