(Antidesma bunius) Cultivars, Harvested From Dipterocarp Forest
of Phupan Valley in Northeast Thailand |

Abstract:
This experiment was carried out in the rainy season (May-October)
of the 2006 at the Department of Biotechnology, Faculty of Technology,
Mahasarakham University, Mahasarakham 44000, Thailand to analyse organic
acids contents in ripe fruits of fifteen Mao Luang cultivars harvested
from dipterocarp forest, Phupan Valley, Sakon Nakhon, Northeast Thailand.
The experiment was laid in a Completely Randomised Design (CRD) with four
replications. The fifteen Mao Luang cultivars were used as treatments.
The results showed that there were two groups of organic acids contents
in ripe fruits of Mao Luang cultivars i.e., major and minor. The major
group of organic acids includes: tartaric acid (7.97-12.16 mg g-1
of fresh weight), ascorbic acid (10.01-16.55 mg g-1 of fresh
weight), citric acid (4.44-11.73 mg g-1 of fresh weight) and
benzoic acid (8.13-17.43 mg g-1 of fresh weight) and the minor
group includes malic acid (3.05-4.52 mg g-1 of fresh weight),
lactic acid (1.12-4.09 mg g-1 of fresh weight), oxalic acid
(1.00-1.45 mg g-1 of fresh weight) and acetic acid (0.19-0.69
mg g-1 of fresh weight). Khumlhai cultivar gave the highest
amount of ascorbic acid followed by Lompat, Phuchong, Sangkrow 2 and Maelookdog
cultivars. Sangkrow 2 and Phuchong cultivars gave the highest ratio between
tartaric and malic acids. Total soluble solid content (TSS%) was highest
with Sangkrow 5 cultivar, whilst Total Organic Acids (TOA) was highest
with Phuchong cultivar and ratio between TSS:TOA was highest with Sangkrow
2 cultivar. Juice % was highest with both Sangkrow 2 and 3 cultivars,
whilst Fapratan and Lompat cultivars ranked the second.
